Between December 1911 and January 1912, both Roald Amundsen (leading his South Pole expedition) and Robert Falcon Scott (leading the Terra Nova Expedition) reached the South Pole within five weeks of each other. But while Scott and his four companions died on the return journey, Amundsen's party managed to reach the geographic south pole first and subsequently return to their base camp at Framheim without loss of human life, suggesting that they were better prepared for the expedition. The contrasting fates of the two teams seeking the same prize at the same time invites comparison.

Overview

The outcomes of the two expeditions were as follows.

  • Priority at the South Pole: Amundsen beat Scott to the South Pole by 34 days.
  • Fatalities: Scott lost five men including himself returning from the pole, out of a team of 65. Amundsen's entire team of 19 returned to Norway safely.
  • Some authors (including Huntford and Fiennes) associate up to two further deaths (the drowning of Robert Brissenden and the suicide of Hjalmar Johansen) with the two expeditions, but these happened outside the Antarctic Circle.

Historically, several factors have been discussed and many contributing factors claimed, including:

  • Priority at the pole: Scott wrote that Amundsen's dogs seriously threatened his own polar aspirations, because dogs, being more cold-tolerant than ponies, would be able to start earlier in the season than Scott's mixed transport of dogs, ponies, and motors.
  • Cherry-Garrard in The Worst Journey in the World agreed but added that in his experience, dogs would not have been able to ascend the Beardmore Glacier.
  • With regards to the causes of the deaths of Scott and his companions, Cherry-Garrard devotes chapter 19 in his book to examine the causes. Among several other factors, he surmised that the rations of Scott's team were inadequate and did not provide enough energy for the men.
  • Much of Scott's hauling was to be done by ponies, which are ill-suited to work on snow and ice without snow-shoes. Their relatively small hooves and large weight caused them to sink into anything other than very firm snow or ice. Oates was opposed to snow-shoes and had left most of them at base camp.
  • Ponies' coats easily became soaked with perspiration during exertion, thus necessitating constant attention with blankets to avoid hypothermia through evaporation. Dogs in contrast do not have sweat glands—they cool themselves via panting, making them less vulnerable to the cold. With ponies, Scott acknowledged he could not depart until 1 November 1911 when the weather would be warmer, leaving him less time to complete the journey.
  • The loss of ponies, several of which had drowned on disintegrating sea-ice, limited the supplies that could be hauled to the depots. Of 19 ponies brought south to aid in laying depots on the Ross Ice Shelf (traversed during the first and final quarters of the trek) nine were lost before the journey began. Further, unlike dogs which could eat the abundant seal and penguin meat found in Antarctica, the ponies' food had to be carried forward from the ship, vastly increasing the stores that had to be transported as Scott's expedition moved towards the pole.
  • Had the one-ton depot been placed at latitude 80° S., as planned, Scott and his two surviving companions could have reached it on their return march. Instead, because Scott refused to drive the ponies to their deaths, despite Oates' urgent advice to do so, the depot was placed some 31 miles short of there. Scott's party died 11 miles south of the depot.
  • The last-minute addition of Lieutenant Henry R. Bowers to the planned four-man pole party may have strained the rationing plan, although the death of Petty Officer Evans weeks later reduced the party to four again.
  • The rations were deficient in B and C vitamins. The party became weaker a few weeks after reaching the pole, despite Scott's racing ambitions before the return march, writing "Now for a desperate struggle to get the news through first [before Amundsen reaches the cablehead in Australia]. I wonder if we can do it."
  • The tins of cooking fuel cached along the return route were found to be partly empty, which forced the men to eat frozen food. Shortage of fuel to melt water likely caused the men to become dehydrated. Apparently the heat of the sun had vaporised part of the fuel, enabling it to escape past the cork stoppers. Amundsen knew about this "creep", and had had the fuel tins soldered shut on the voyage to Antarctica, see below.
  • The weather on the return march seems to have been unusually bad. In particular, when the party reached the Great Ice Barrier, the temperature was much lower than expected for the season, making the surface much less suitable for the sledge runners. Furthermore, the tailwind which they had expected to aid them home did not appear. Scott wrote, in his final "Message to the Public": "...our wreck is certainly due to this sudden advent of severe weather...."
  • The complexity of the transportation plan made it vulnerable. It depended in part on motor-sledges, ponies, dogs, and southerly winds to assist the sledges (which were fitted with sails). Half of the distance was intended to be covered by man-hauling (and sails whenever conditions permitted). Scott's daily marches were limited to the endurance of the slowest team, the man-haulers who were instructed to advance 15 miles a day. The ponies marched by night and rested when the sun was warmer, Meares remained idle in camp with the much faster dogs for many hours, before catching up at the end of the day.

Sullivan states that it was the last factor that probably was decisive. He states:

Man is a poor beast of burden, as was shown in the terrible experience of Scott, Shackleton, and Wilson in their thrust to the south of 1902–3. However, Scott relied chiefly on man-hauling in 1911–12 because ponies could not ascend the glacier midway to the Pole. The Norwegians correctly guessed that dog teams could go all the way. Furthermore, they used a simple plan, based on their native skill with skis and on dog-driving methods that were tried and true. The moon will be reached by burning up a succession of rocket stages and casting them off. This, in effect, is what the Norwegians did with their dogs, the weaker animals being sacrificed to feed the other animals and the men themselves.

Objectives of the expeditions

Scott and his financial backers saw the expedition as having a scientific basis, while also wishing to reach the pole. However, it was recognised by all involved that the South Pole was the primary objective ("The Southern Journey involves the most important object of the Expedition" – Scott), and had priority in terms of resources, such as the best ponies and all the dogs and motor sledges as well as involvement of the vast majority of the expedition personnel. Scott and his team knew the expedition would be judged on his attainment of the pole ("The ... public will gauge the result of the scientific work of the expedition largely in accordance with the success or failure of the main object" – Scott). He was prepared to make a second attempt the following year (1912–13) if this attempt failed and had Indian Army mules and additional dogs delivered in anticipation. In fact the mules were used by the team that discovered the dead bodies of Scott, Henry Robertson Bowers, and Edward Adrian Wilson in November 1912, but proved even less useful than the ponies, according to Cherry-Garrard.

Amundsen's expedition was planned to reach the South Pole. This was a plan he conceived in 1909.

Amundsen's expedition did conduct geographical work under Kristian Prestrud who conducted an expedition to King Edward VII Land while Amundsen was undertaking his attempt at the pole.

Base camps

Amundsen camped on the Ross Ice Shelf at the Bay of Whales at approx. 78°30′S, which is 52 nautical miles (96 km) closer to the pole than Scott's camp (at 77°38′S) which was 350 nautical miles west of Amundsen, on Ross Island. Amundsen had deduced that, as the Trans-Antarctic Mountains ran northwest to southeast then if he were to meet a mountain range on his route then the time spent at the high altitude of the Antarctic plateau would be less than Scott's. Scott's base was at Cape Evans on Ross Island, with access to the Trans-Antarctic mountain range to the west, and was a better base for geological exploration. He had based his previous expedition in the same area. However, he knew it to be poor as a route to the pole as he had to start before sea ice melted and had suffered delay in returning while waiting for the sea ice to freeze. They also had to make detours around Ross Island and its known crevassed areas which meant a longer journey. The crossing of the Ross Ice Shelf was an onerous task for the ponies. Scott had advanced considerable stores across the ice shelf the year before to allow the ponies to carry lighter loads over the early passage across the ice. Even so, he had to delay the departure of the ponies until 1 November rather than 24 October when the dogs and motor sledges set off.

Consequently, the Motor Party spent 6 days at the Mount Hooper Depot waiting for Scott to arrive.

Methods of transport

Motor sledges

The major comparison between Scott and Amundsen has focused on the choice of draft transport —dog versus pony/man-hauling. In fact Scott took dogs, ponies and three "motor sledges". Scott spent nearly seven times the amount of money on his motor sledges than on the dogs and horses combined. They were therefore a vital part of the expedition. Unfortunately, Scott decided to leave behind the engineer, Lieutenant Commander Reginald William Skelton who had created and trialled the motor sledges. This was due to the selection of Lieutenant E.R.G.R. "Teddy" Evans as the expedition's second in command. As Evans was junior in rank to Skelton, he insisted that Skelton could not come on the expedition. Scott agreed to this request and Skelton's experience and knowledge were lost. One of the original three motor sledges was a failure even before the expedition set out; the heavy sledge was lost through thin ice on unloading it from the ship. The two remaining motor sledges failed relatively early in the main expedition because of repeated faults. Skelton's experience might have been valuable in overcoming the failures.

Ponies vs dogs

Scott had used dogs on his first (Discovery) expedition and felt they had failed. On that journey, Scott, Shackleton, and Wilson started with three sledges and 13 dogs. But on that expedition, the men had not properly understood how to travel on snow with the use of dogs. The party had skis but were too inexperienced to make good use of them. As a result, the dogs travelled so fast that the men could not keep up with them. The Discovery expedition had to increase their loads to slow the dogs down. Additionally, the dogs were fed Norwegian dried fish, which did not agree with them and soon they began to deteriorate. The whole team of dogs eventually died (and were eaten), and the men took over hauling the sleds.

Scott's opinion was reinforced by Shackleton's experience on the Nimrod expedition, which got to within 97.5 nautical miles (180.6 km; 112.2 mi) of the pole. Shackleton used ponies. Scott planned to use ponies only to the base of the Beardmore Glacier (one-quarter of the total journey) and man-haul the rest of the journey. Scott's team had developed snow shoes for his ponies, and trials showed they could significantly increase daily progress. However, Lawrence Oates, whom Scott had made responsible for the ponies, was reluctant to use the snow shoes and Scott failed to insist on their use.

There was plenty of evidence that dogs could succeed in the achievements of William Speirs Bruce in his Arctic, Antarctic, and Scottish National Antarctic Expedition, Amundsen in the Gjøa North West passage expedition, Fridtjof Nansen's crossing of Greenland, Robert Peary's three attempts at the North Pole, Eivind Astrup's work supporting Peary, Frederick Cook's discredited North Pole expedition, and Otto Sverdrup's explorations of Ellesmere Island. Moreover, Scott ignored the direct advice he received (while attending trials of the motor sledges in Norway) from Nansen, the most famous explorer of the day, who told Scott to take "dogs, dogs and more dogs".

At the time of the events, the expert view in England had been that dogs were of dubious value as a means of Antarctic transport. Broadly speaking, Scott saw two ways in which dogs may be used—they may be taken with the idea of bringing them all back safe and sound, or they may be treated as pawns in the game, from which the best value is to be got regardless of their lives. He stated that if, and only if, the comparison was made with a dog sledge journey which aimed to preserve the dogs' lives, 'I am inclined to state my belief that in the polar regions properly organised parties of men will perform as extended journeys as teams of dogs.' On the other hand, if the lives of the dogs were to be sacrificed, then 'the dog-team is invested with a capacity for work which is beyond the emulation of men. To appreciate this is a matter of simple arithmetic'. But efficiency notwithstanding, he expressed "reluctance" to use dogs in this way: "One cannot calmly contemplate the murder of animals which possess such intelligence and individuality, which have frequently such endearing qualities, and which very possibly one has learnt to regard as friends and companions."

Amundsen, by contrast, took an entirely utilitarian approach. Amundsen planned from the start to have weaker animals killed to feed the other animals and the men themselves. He expressed the opinion that it was less cruel to feed and work dogs correctly before shooting them, than it would be to starve and overwork them to the point of collapse. Amundsen and his team had similar affection for their dogs as those expressed above by the English, but they "also had agreed to shrink from nothing in order to achieve our goal". The British thought such a procedure was distasteful, though they were willing to eat their ponies.

Amundsen had used the opportunity of learning from the Inuit while on his Gjøa North West passage expedition of 1905. He recruited experienced dog drivers. To make the most of the dogs he paced them and deliberately kept daily mileages shorter than he need have for 75 percent of the journey, and his team spent up to 16 hours a day resting. His dogs could eat seals and penguins hunted in the Antarctic while Scott's pony fodder had to be brought all the way from England in their ship. It has been later shown that seal meat with the blubber attached is the ideal food for a sledge dog. Amundsen went with 52 dogs, and came back with 11.

What Scott did not realise is a sledge dog, if it is to do the same work as a man, will require the same amount of food. Furthermore, when sledge dogs are given insufficient food they become difficult to handle. The advantage of the sledge dog is its greater mobility. Not only were the Norwegians accustomed to skiing, which enabled them to keep up with their dogs, but they also understood how to feed them and not overwork them.

Walking vs skiing on snow

Scott took the Norwegian pilot and skier Tryggve Gran to the Antarctic on the recommendation of Nansen to train his expedition to ski, but although a few of his party began to learn, he made no arrangements for compulsory training for the full party. Gran (possibly because he was Norwegian) was not included in the South Pole party, which could have made a difference. Gran was, one year later, the first to locate the deceased Scott and his remaining companions in their tent just some 18 km (11 miles) short of One Ton depot, that might have saved their lives had they reached it.

Scott would subsequently complain in his diary, while well into his journey and therefore too late to take any corrective action and after over 10 years since the Discovery expedition, that "Skis are the thing, and here are my tiresome fellow countrymen too prejudiced to have prepared themselves for the event".

Amundsen, on his side, recruited a team of well experienced skiers, all Norwegians who had skied from an early age. He also recruited a champion skier, Olav Bjaaland, as the front runner. The Amundsen party gained weight on their return travel from the South Pole.

Weather conditions

Scott and Shackleton's experience in 1903 and 1907 gave them first-hand experience of average conditions in Antarctica. Simpson, Scott's meteorologist 1910–1912, charted the weather during their expedition, often taking two readings a day. On their return to the Ross Ice Shelf, Scott's group experienced prolonged low temperatures from 27 February until 10 March which have only been matched once in 15 years of current records. The exceptional severity of the weather meant they failed to make the daily distances they needed to get to the next depot. This was a serious position as they were short of fuel and food. When Scott, Wilson, and Bowers died (Petty Officer Edgar Evans and Lawrence Oates had died earlier during the return from the South Pole) they were 18 kilometres (11 mi) short of One-Ton Depot, which was 230 kilometres (140 mi) from Corner Camp, where they would have been safe.

On the other hand, Cherry-Garrard had travelled nearly 500 kilometres (300 mi) in the same area, during the same time period and same temperatures, using a dog team. Scott also blamed "a prolonged blizzard". But while there is evidence to support the low temperatures, there is only evidence for a "normal" two- to four-day blizzard, and not the ten days that Scott claims.

Route marking and depot laying

One of Amundsen's depots.

During depot laying in February 1911, Roald Amundsen had his first (and last) 290 kilometres (180 mi) of his route marked like a Norwegian ski course using marker flags initially every eight miles. He added to this by using food containers painted black, resulting in a marker every mile. From 82 degrees on, Amundsen built a 6 ft (1.8 m) cairn every three miles with a note inside recording the cairn's position, the distance to the next depot, and direction to the next cairn. In order not to miss a depot considering the snow and great distances, Amundsen took precautions. Each depot laid out up to 85 degrees (laid out every degree of latitude) had a line of bamboo flags laid out transversely every half-mile for five miles on either side of the depot, ensuring that the returning party could locate the designated depot.

Scott relied on depots much less frequently laid out. For one distance where Amundsen laid seven depots, Scott laid only two. Routes were marked by the walls made at lunch and evening stops to protect the ponies. Depots had a single flag. As a result, Scott has much concern recorded in his diaries over route finding, and experienced close calls about finding depots. It is also clear that Scott's team did not travel on several days, because the swirling snow hid their three-month-old outward tracks. With better depot and route marking they would have been able to travel on more days with a following wind which would have filled the sail attached to their sledge, and so travel further, and might have reached safety.

Food and fuel

Evans, Bower, Wilson and Scott have a meal.

By the time they arrived at the pole, the health of Scott's team had significantly deteriorated, whereas Amundsen's team actually gained weight during the expedition. Although Scott's team managed to maintain the scheduled pace for most of the return leg, and hence was virtually always on full rations, their condition continued to worsen rapidly. (The only delay occurred when they were held for four days by a blizzard, and had to open their summit rations early as a consequence.)

Apsley Cherry-Garrard in his analysis of the expedition estimated that even under optimistic assumptions the summit rations contained only a little more than half the calories actually required for the man-hauling of sledges. A carefully planned 2006 re-enactment of both Amundsen's and Scott's travels, sponsored by the BBC, confirmed Cherry-Garrard's theory. The British team had to abort their tour due to the severe weight loss of all members. The experts hinted that Scott's reports of unusually bad surfaces and weather conditions might in part have been due to their exhausted state which made them feel the sledge weights and the chill more severely.

Scott's calculations for the supply requirements were based on a number of expeditions, both by members of his team (e.g., Wilson's trip with Cherry-Garrard and Bowers to the Emperor penguin colony which had each man on a different type of experimental ration), and by Shackleton. Apparently, Scott didn't take the strain of prolonged man-hauling at high altitudes sufficiently into account.

Since the rations contained no B and C vitamins, the only source of these vitamins during the trek was from the slaughter of ponies or dogs. This made the men progressively malnourished, manifested most clearly in the form of scurvy.

Scott also had to fight with a shortage of fuel due to leakage from stored fuel cans which used leather washers. This was a phenomenon that had been noticed previously by other expeditions, but Scott took no measures to prevent it. Amundsen, in contrast, had learned the lesson and had his fuel cans soldered closed. A fuel depot he left on Betty's Knoll was found 50 years later still full.

Dehydration may also have been a factor. Amundsen's team had plenty of fuel due to better planning and soldered fuel cans. Scott had a shortage of fuel and was unable to melt as much water as Amundsen. At the same time Scott's team were more physically active in man-hauling the sledges.

Clothing and goggles

Present-day explorer Ranulph Fiennes and others have asserted that Scott's team was appropriately dressed for man-hauling in their woolen and wind-proof clothing and that Amundsen's, because they were skiing, was appropriately dressed in furs. Skiing at the pace of a dog team is a strenuous activity, yet Amundsen never complained about the clothing being too hot. That is because the furs are worn loosely so air circulates and sweat evaporates. Scott's team, on the other hand, made regular complaints about the cold.

Amundsen's team did initially have problems with their boots. However, the depot-laying trips of January and February 1911 and an abortive departure to the South Pole on 8 September 1911 allowed changes to be made before it was too late.

Scott's team suffered regularly from snow blindness and sometimes this affected over half the team at any one time. By contrast, there was no recorded case of snow blindness during the whole of Amundsen's expedition. On the return journey, Amundsen's team rested during the "day" (when the sun was in front of them) and travelled during the "night" (when the sun was behind them) to minimise the effects of snow blindness.

Delay in meeting Scott's returning party

In 1921, 'Teddy' Evans wrote in his book South with Scott that Scott had left the following written orders at Cape Evans.

About the first week of February I should like you to start your third journey to the South, the object being to hasten the return of the third Southern unit [the polar party] and give it a chance to catch the ship. The date of your departure must depend on news received from returning units, the extent of the depot of dog food you have been able to leave at One Ton Camp, the state of the dogs, etc ...It looks at present as though you should aim at meeting the returning party about March 1 in Latitude 82 or 82.30.

He did however place a lesser importance upon this journey than that of replenishing the food rations at One Ton Depot.

He continued his instructions in the next paragraph "You will of course understand that whilst the object of your third journey is important, that of the second is vital. At all hazards three X.S. units of provision must be got to One Ton Camp by the date named (19th January), and if the dogs are unable to perform this task, a man party must be organised." with that qualification he closed his notes regarding his instructions for the dogs.

Expedition member Apsley Cherry-Garrard did not mention Scott's order in his 1922 book The Worst Journey in the World. However, in the 1948 preface to his book, he discusses Scott's order. Cherry-Garrard writes that he and Edward Atkinson reached Cape Evans on 28 January. Scott had estimated Atkinson would reach camp by 13 January. Atkinson, now the senior officer discovered that the dog handler Cecil Meares had resigned from the expedition and that neither Meares nor anyone else had resupplied dog food to the depots. Cherry-Garrard also wrote "In my opinion he [Atkinson] would not have been fit to take out the dogs in the first week of February".

On 13 February, Atkinson set off on the first lap southwards to Hut Point with the dog assistant, Dimitri Gerov, and the dogs to avoid being cut off by disintegrating sea ice. Atkinson and Gerov were still at Hut Point when, on 19 February, Tom Crean arrived on foot from the Barrier and reported that Lt Edward Evans was lying seriously ill in a tent some 55 kilometres (35 mi) to the south, and in urgent need of rescue. Atkinson decided that this mission was his priority, and set out with the dogs to bring Evans back. This was achieved; the party was back at Hut Point on 22 February.

Atkinson sent a note back to the Cape Evans base camp requesting either the meteorologist Wright or Cherry-Garrard to take over the task of meeting Scott with the dogs. Chief meteorologist Simpson was unwilling to release Wright from his scientific work, and Atkinson therefore selected Apsley Cherry-Garrard. It was still not in Atkinson's mind that Cherry-Garrard's was a relief mission, and according to Cherry-Garrard's account, told him to "use his judgement" as to what to do in the event of not meeting the polar party by One Ton, and that Scott's orders were that the dogs must not be risked. Cherry-Garrard left with Gerov and the dogs on 26 February, carrying extra rations for the polar party to be added to the depot and 24 days' of dog food. They arrived at One Ton Depot on 4 March and did not proceed further south. Instead, he and Gerov, after waiting there for Scott for several days, apparently mostly in blizzard conditions (although no blizzard was recorded by Scott some 100 miles further south until 10 March), they returned to Hut Point on 16 March, in poor physical condition and without news of the polar party.

On the return journey from the pole, Scott reached the 82.30°S meeting point for the dog teams three days ahead of schedule, around 27 February 1912. Scott's diary for that day notes "We are naturally always discussing possibility of meeting dogs, where and when, etc. It is a critical position. We may find ourselves in safety at the next depot, but there is a horrid element of doubt." By 10 March it became clear that the dog teams were not coming: "The dogs which would have been our salvation have evidently failed. Meares [the dog-driver] had a bad trip home I suppose. It's a miserable jumble."

Around 25 March, awaiting death in his tent at latitude 79.40°S, Scott speculated, in a farewell letter to his expedition treasurer Sir Edgar Speyer, that he had overshot the meeting point with the dog relief teams, writing "We very nearly came through, and it's a pity to have missed it, but lately I have felt that we have overshot our mark. No-one is to blame and I hope no attempt will be made to suggest that we had lacked support." (Farewell letter to Sir Edgar Speyer, cited from Karen May 2012.)

Other reasons for Scott's failure

Geology samples

Scott's team continued to haul over 14 kg (30 lb) of rock samples. This would appear to be a major handicap when pulling a sledge in a race against the weather and a shortage of food and fuel. Scott could have left the samples at one of the cairns along the way to be picked up later. However, Ranulph Fiennes has suggested that the extra weight would not have been a major handicap. Tryggve Gran on the other hand thought "they might have saved themselves the bother".

Final five-man team

Scott's planning, equipment and rations had been based on three sledge teams of four men ascending the Beardmore, with a team turning back every 10 days or so as rations required finally leaving one four-man team to attempt the pole. At the last moment when down to two teams (Scott's and Evans's) Scott decided to send a returning party of three, and take on five. This increased the cooking time for the team of five and affected the fuel supply. It also meant the Evans party of three had to try to split the ration pack (at a time when they were cold and tired and later when one member was suffering from scurvy) to leave an allowance for the fifth man in Scott's party. This also will have affected the seepage of fuel from cans which were opened and then re-closed and left for several weeks before Scott's team got to them. Moreover, for some unexplained reason Scott had ordered Evans's team to cache their skis a week before so Bowers (the fifth man) walked to the pole and back to the cached skis (360 miles) while the rest of Scott's team skied.

Misuse of the dog team

For no clear reason Scott took the dogs on 140 miles further than originally planned. This meant killing the ponies early (and starting man-hauling earlier) to feed the dogs for no obvious benefit to the overall expedition. Scott also gave conflicting and changing orders for their use to each returning party. It was only in late February 1912 that it was discovered that the final supplies needed by Scott's returning party had not been delivered to One Ton Depot. Cherry-Garrard was sent with these supplies on 25 February 1912 and he was relieved to discover that he had beaten Scott's team to the depot. He also found that promised supplies of dog food were not in place. Cherry-Garrard remained at the depot, within 100 kilometres (60 mi) of Scott, 4–10 March 1912 when he could possibly have saved Scott, Wilson, Bowers, and Oates if the management of the dog team had been better.

Navigation

Amundsen used prepared navigation sheets that simplified the calculations for his team when they were tired and cold. Four out of his team of five were qualified navigators. Amundsen's expedition also used a sextant during the journey, which is a relatively light and simple piece of equipment. He also attended a symposium that reviewed how to fix position at high latitudes. Scott used a theodolite which is heavier and requires more mental arithmetic. Scott also lacked navigators having only one per team. Scott dismissed Cherry-Garrard's request for navigational training and Wilson only attempted to learn how to read latitudes at the last moment.

Camp routine

Amundsen used canisters that left his sledges permanently lashed and loaded. Scott's team had to unload, and load and relash their sledge at every camp, no matter what the weather.

Roald Engelbregt Gravning Amundsen (UK: /ˈɑːmʊndsən/, US: /-məns-/; Norwegian: [ˈruːɑɫ ˈɑmʉnsən] (About this soundlisten); 16 July 1872 – c. 18 June 1928) was a Norwegian explorer of polar regions and a key figure of the Heroic Age of Antarctic Exploration. He led the first expedition to traverse the Northwest Passage by sea, from 1903 to 1906, and the first expedition to the South Pole in 1911. He led the first expedition proven to have reached the North Pole in a dirigible in 1926. He disappeared while taking part in a rescue mission for the airship Italia in 1928.

Early life

Amundsen was born into a family of Norwegian shipowners and captains in Borge, between the towns Fredrikstad and Sarpsborg. His parents were Jens Amundsen and Hanna Sahlqvist. Roald was the fourth son in the family. His mother wanted him to avoid the family maritime trade and encouraged him to become a doctor, a promise that Amundsen kept until his mother died when he was aged 21. He promptly quit university for a life at sea.

When he was fifteen years old, Amundsen was enthralled by reading Sir John Franklin's narratives of his overland Arctic expeditions. Amundsen wrote "I read them with a fervid fascination which has shaped the whole course of my life".

Polar treks

Belgian Antarctic Expedition

RV Belgica frozen in the ice, 1898

Amundsen joined the Belgian Antarctic Expedition as first mate. This expedition, led by Adrien de Gerlache using the ship the RV Belgica, became the first expedition to overwinter in Antarctica. The Belgica, whether by mistake or design, became locked in the sea ice at 70°30′S off Alexander Island, west of the Antarctic Peninsula. The crew endured a winter for which they were poorly prepared.

By Amundsen's own estimation, the doctor for the expedition, the American Frederick Cook, probably saved the crew from scurvy by hunting for animals and feeding the crew fresh meat. In cases where citrus fruits are lacking, fresh meat from animals that make their own vitamin C contains enough of the vitamin to prevent scurvy, and even partly treat it. This was an important lesson for Amundsen's future expeditions.

Northwest Passage

Roald Amundsen, around 1908.

In 1903, Amundsen led the first expedition to successfully traverse Canada's Northwest Passage between the Atlantic and Pacific oceans. He planned a small expedition of six men in a 45-ton fishing vessel, Gjøa, in order to have flexibility. His ship had relatively shallow draft. His technique was to use a small ship and hug the coast. Amundsen had the ship outfitted with a small 13 horsepower single-screw paraffin engine.

They traveled via Baffin Bay, the Parry Channel and then south through Peel Sound, James Ross Strait, Simpson Strait and Rae Strait. They spent two winters at King William Island, in the harbor of what is today Gjoa Haven. During this time, Amundsen and the crew learned from the local Netsilik Inuit about Arctic survival skills, which he found invaluable in his later expedition to the South Pole. For example, he learned to use sled dogs for transportation of goods and to wear animal skins in lieu of heavy, woolen parkas, which could not keep out the cold when wet.

Leaving Gjoa Haven, he sailed west and passed Cambridge Bay, which had been reached from the west by Richard Collinson in 1852. Continuing to the south of Victoria Island, the ship cleared the Canadian Arctic Archipelago on 17 August 1905. It had to stop for the winter before going on to Nome on Alaska's Pacific coast. The nearest telegraph station was 500 miles (800 km) away in Eagle. Amundsen traveled there overland to wire a success message on 5 December, then returned to Nome in 1906. Later that year he was elected to the American Antiquarian Society.

At this time, Amundsen learned of the dissolution of the union between Norway and Sweden, and that he had a new king. The explorer sent the new king, Haakon VII, news that his traversing the Northwest Passage "was a great achievement for Norway". He said he hoped to do more and signed it "Your loyal subject, Roald Amundsen." The crew returned to Oslo in November 1906, after almost three-and-a-half years abroad. Gjøa was returned to Norway in 1972. After a 45-day trip from San Francisco on a bulk carrier, she was placed on land outside the Fram Museum in Oslo, where she is now situated inside her own dedicated building at the museum.

South Pole Expedition

Amundsen next planned to take an expedition to the North Pole and explore the Arctic Basin. Finding it difficult to raise funds, when he heard in 1909 that the Americans Frederick Cook and Robert Peary had claimed to reach the North Pole as a result of two different expeditions, he decided to reroute to Antarctica. He was not clear about his intentions, and Robert F. Scott and the Norwegian supporters felt misled. Scott was planning his own expedition to the South Pole that year. Using the ship Fram, earlier used by Fridtjof Nansen, Amundsen left Oslo for the south on 3 June 1910. At Madeira, Amundsen alerted his men that they would be heading to Antarctica, and sent a telegram to Scott: "Beg to inform you Fram proceeding Antarctic – Amundsen."

Nearly six months later, the expedition arrived at the eastern edge of the Ross Ice Shelf (then known as "the Great Ice Barrier"), at a large inlet called the Bay of Whales, on 14 January 1911. Amundsen established his base camp there, calling it Framheim. Amundsen eschewed the heavy wool clothing worn on earlier Antarctic attempts in favour of adopting Inuit-style furred skins.

Using skis and dog sleds for transportation, Amundsen and his men created supply depots at 80°, 81° and 82° South on the Barrier, along a line directly south to the Pole. Amundsen also planned to kill some of his dogs on the way and use them as a source for fresh meat. A small group, including Hjalmar Johansen, Kristian Prestrud and Jørgen Stubberud, set out on 8 September, but had to abandon their trek due to extreme temperatures. The painful retreat caused a quarrel within the group, and Amundsen sent Johansen and the other two men to explore King Edward VII Land.

A second attempt, with a team of five made up of Olav Bjaaland, Helmer Hanssen, Sverre Hassel, Oscar Wisting and Amundsen, departed base camp on 19 October. They took four sledges and 52 dogs. Using a route along the previously unknown Axel Heiberg Glacier, they arrived at the edge of the Polar Plateau on 21 November after a four-day climb. The team and 16 dogs arrived at the pole on 14 December, a month before Scott's group. Amundsen named their South Pole camp Polheim. Amundsen renamed the Antarctic Plateau as King Haakon VII's Plateau. They left a small tent and letter stating their accomplishment, in case they did not return safely to Framheim.

The team arrived at Framheim on 25 January 1912, with 11 surviving dogs. They made their way off the continent and to Hobart, Australia, where Amundsen publicly announced his success on 7 March 1912. He telegraphed news to backers.

Amundsen's expedition benefited from his careful preparation, good equipment, appropriate clothing, a simple primary task, an understanding of dogs and their handling, and the effective use of skis. In contrast to the misfortunes of Scott's team, Amundsen's trek proved relatively smooth and uneventful.

North Polar Expeditions and Northeast Passage

Northeast Passage

Maud in June 1918

In 1918, an expedition Amundsen began with a new ship, Maud, lasted until 1925. Maud was carefully navigated through the ice west to east through the Northeast Passage. With him on this expedition were Oscar Wisting and Helmer Hanssen, both of whom had been part of the team to reach the South Pole. In addition, Henrik Lindstrøm was included as a cook. He suffered a stroke and was so physically reduced that he could not participate.

The goal of the expedition was to explore the unknown areas of the Arctic Ocean, strongly inspired by Fridtjof Nansen's earlier expedition with Fram. The plan was to sail along the coast of Siberia and go into the ice farther to the north and east than Nansen had. In contrast to Amundsen's earlier expeditions, this was expected to yield more material for academic research, and he carried the geophysicist Harald Sverdrup on board.

The voyage was to the northeasterly direction over the Kara Sea. Amundsen planned to freeze the Maud into the polar ice cap and drift towards the North Pole – as Nansen had done with the Fram – and he did so off Cape Chelyuskin. But, the ice became so thick that the ship was unable to break free, although it was designed for such a journey in heavy ice. In September 1919, the crew got the ship loose from the ice, but it froze again after eleven days somewhere between the New Siberian Islands and Wrangel Island.

During this time, Amundsen suffered a broken arm and was attacked by polar bears. As a result, he participated little in the work outdoors, such as sleigh rides and hunting. He, Hanssen, and Wisting, along with two other men, embarked on an expedition by dog sled to Nome, Alaska, more than 1,000 kilometres (620 mi) away. But they found that the ice was not frozen solid in the Bering Strait, and it could not be crossed. They sent a telegram from Anadyr to signal their location.

After two winters frozen in the ice, without having achieved the goal of drifting over the North Pole, Amundsen decided to go to Nome to repair the ship and buy provisions. Several of the crew ashore there, including Hanssen, did not return on time to the ship. Amundsen considered Hanssen to be in breach of contract, and dismissed him from the crew.

During the third winter, Maud was frozen in the western Bering Strait. She finally became free and the expedition sailed south, reaching Seattle, in the American Pacific Northwest in 1921 for repairs. Amundsen returned to Norway, needing to put his finances in order. He took with him two young indigenous girls, a four-year-old he adopted, Kakonita, and her companion Camilla. When Amundsen went bankrupt two years later, however, he sent the girls to be cared for by Camilla's father, who lived in eastern Russia.

In June 1922, Amundsen returned to Maud, which had been sailed to Nome. He decided to shift from the planned naval expedition to aerial ones, and arranged to charter a plane. He divided the expedition team in two: one part, led by him, was to winter over and prepare for an attempt to fly over the pole in 1923. The second team on Maud, under the command of Wisting, was to resume the original plan to drift over the North Pole in the ice. The ship drifted in the ice for three years east of the New Siberian Islands, never reaching the North Pole. It was finally seized by Amundsen's creditors as collateral for his mounting debt.

Aerial Expeditions to the North Pole

Roald Amundsen in Svalbard (1925)

The 1923 attempt to fly over the Pole failed. Amundsen and Oskar Omdal, of the Royal Norwegian Navy, tried to fly from Wainwright, Alaska, to Spitsbergen across the North Pole. When their aircraft was damaged, they abandoned the journey. To raise additional funds, Amundsen traveled around the United States in 1924 on a lecture tour. Although he was unable to reach the North Pole, the scientific results of the expedition, mainly the work of Sverdrup, have proven to be of considerable value. Much of the carefully collected scientific data was lost during the ill-fated journey of Peter Tessem and Paul Knutsen, two crew members sent on a mission by Amundsen. The scientific materials were later retrieved by Russian scientist Nikolay Urvantsev from where they had been abandoned on the shores of the Kara Sea.

In 1925, accompanied by Lincoln Ellsworth, pilot Hjalmar Riiser-Larsen, flight mechanic Karl Feucht and two other team members, Amundsen took two Dornier Do J flying boats, the N-24 and N-25, to 87° 44′ north. It was the northernmost latitude reached by plane up to that time. The aircraft landed a few miles apart without radio contact, yet the crews managed to reunite. The N-24 was damaged. Amundsen and his crew worked for more than three weeks to clean up an airstrip to take off from ice. They shovelled 600 tons of ice while consuming only one pound (400 g) of daily food rations. In the end, the six crew members were packed into the N-25. In a remarkable feat, Riiser-Larsen took off, and they barely became airborne over the cracking ice. They returned triumphant when everyone thought they had been lost forever.

In 1926, Amundsen and 15 other men (including Ellsworth, Riiser-Larsen, Oscar Wisting, and the Italian air crew led by aeronautical engineer Umberto Nobile made the first crossing of the Arctic in the airship Norge, designed by Nobile. They left Spitsbergen on 11 May 1926, flew over the North Pole on 12 May, and landed in Alaska the following day.

Controversy over Polar Priority

The three previous claims to have arrived at the North Pole: Frederick Cook in 1908; Robert Peary in 1909; and Richard E. Byrd in 1926 (just a few days before the Norge) are disputed by some, as being either of dubious accuracy or outright fraud. If these other claims are false, the crew of the Norge would be the first explorers verified to have reached the North Pole, floated over it in the Norge in 1926. If the Norge expedition was the first to the North Pole, Amundsen and Oscar Wisting were the first men to have reached both geographical poles, by ground or by air.

Disappearance and death

Amundsen's Latham 47 flying boat

Amundsen disappeared on 18 June 1928 while flying on a rescue mission in the Arctic. His team included Norwegian pilot Leif Dietrichson, French pilot René Guilbaud, and three more Frenchmen. They were seeking missing members of Nobile's crew, whose new airship Italia had crashed while returning from the North Pole. Amundsen's French Latham 47 flying boat never returned.

Later, a wing-float and bottom gasoline tank from the plane, which had been adapted as a replacement wing-float, were found near the Tromsø coast. It is believed that the plane crashed in fog in the Barents Sea, and that Amundsen and his crew were killed in the wreck, or died shortly afterward. The search for Amundsen and team was called off in September 1928 by the Norwegian government, and the bodies were never found.

In 2004 and in late August 2009, the Royal Norwegian Navy used the unmanned submarine Hugin 1000 to search for the wreckage of Amundsen's plane. The searches focused on a 40-square-mile (100 km2) area of the sea floor, and were documented by the German production company ContextTV. They found nothing from the Amundsen flight.

Honours

In 1925, Amundsen was awarded the Hans Egede Medal by the Royal Danish Geographical Society.

Legacy

Owing to Amundsen's numerous significant accomplishments in polar exploration, many places in both the Arctic and Antarctic are named after him. The Amundsen–Scott South Pole Station, operated by the United States Antarctic Program, was jointly named in honour of Amundsen and his rival. British novelist Roald Dahl was named after Amundsen, as was Nobel Prize laureate Roald Hoffmann.

The 1969 film The Red Tent tells the story of the Nobile expedition and Amundsen's disappearance. Sean Connery plays the role of Amundsen.

Huntford's book was adapted into the TV serial The Last Place on Earth. It aired in 1985 and featured Sverre Anker Ousdal as Amundsen.

On 15 February 2019, a biographic Norwegian film titled Amundsen, directed by Espen Sandberg, was released.

European-Inuit descendant claims

At least two Inuit people in Gjøa Haven with European ancestry have claimed to be descendants of Amundsen, from the period of their extended winter stay on King Williams Island from 1903 to 1905. Accounts by members of the expedition told of their relations with Inuit women, and historians have speculated that Amundsen might also have taken a partner, although he wrote a warning against this.

Specifically, half-brothers Bob Konona and Paul Ikuallaq say that their father Luke Ikuallaq told them on his deathbed that he was the son of Amundsen. Konona said that their father Ikuallaq was left out on the ice to die after his birth, as his European ancestry made him illegitimate to the Inuit, threatening their community. His Inuit grandparents saved him.

In 2012, Y-DNA analysis, with the families' permission, showed that Ikuallaq was not a match to the direct male line of Amundsen. Not all descendants claiming European ancestry have been tested for a match to Amundsen, nor has there been a comparison of Ikuallaq's DNA to that of other European members of Amundsen's crew.

History of Antarctica

From Wikipedia, the free encyclopedia

The history of Antarctica emerges from early Western theories of a vast continent, known as Terra Australis, believed to exist in the far south of the globe. The term Antarctic, referring to the opposite of the Arctic Circle, was coined by Marinus of Tyre in the 2nd century AD.

The rounding of the Cape of Good Hope and Cape Horn in the 15th and 16th centuries proved that Terra Australis Incognita ("Unknown Southern Land"), if it existed, was a continent in its own right. In 1773 James Cook and his crew crossed the Antarctic Circle for the first time but although they discovered nearby islands, they did not catch sight of Antarctica itself. It is believed he was as close as 240 km (150 mi) from the mainland.

On 27 January 1820, a Russian expedition led by Fabian Gottlieb von Bellingshausen and Mikhail Lazarev discovered an ice shelf at Princess Martha Coast that later became known as the Fimbul Ice Shelf. Bellingshausen and Lazarev became the first explorers to see and officially discover the land of the continent of Antarctica. Three days later, on 30 January 1820, a British expedition captained by Irishman Edward Bransfield sighted Trinity Peninsula, and ten months later an American sealer Nathaniel Palmer sighted Antarctica on 17 November 1820. The first landing was probably just over a year later when American Captain John Davis, a sealer, set foot on the ice.

Several expeditions attempted to reach the South Pole in the early 20th century, during the "Heroic Age of Antarctic Exploration". Many resulted in injury and death. Norwegian Roald Amundsen finally reached the Pole on 13 December 1911, following a dramatic race with the Briton Robert Falcon Scott.

Early exploration

The search for Terra Australis Incognita

In 1570 a rudimentary map by Ortelius showed the imagined link between the proposed continent of Antarctica and South America. Note also the proposed landmasses surrounding the North Pole.

Aristotle speculated, "Now since there must be a region bearing the same relation to the southern pole as the place we live in bears to our pole...".

It was not until Prince Henry the Navigator began in 1418 to encourage the penetration of the torrid zone in the effort to reach India by circumnavigating Africa that European exploration of the southern hemisphere began. In 1473 Portuguese navigator Lopes Gonçalves proved that the equator could be crossed, and cartographers and sailors began to assume the existence of another, temperate continent to the south of the known world.

The doubling of the Cape of Good Hope in 1487 by Bartolomeu Dias first brought explorers within touch of the Antarctic cold, and proved that there was an ocean separating Africa from any Antarctic land that might exist.

Ferdinand Magellan, who passed through the Straits of Magellan in 1520, assumed that the islands of Tierra del Fuego to the south were an extension of this unknown southern land, and it appeared as such on a map by Ortelius: Terra australis recenter inventa sed nondum plene cognita ("Southern land recently discovered but not yet fully known").

Map from 1771, showing "Terres Australes" label without any charted landmass.

European geographers connected the coast of Tierra del Fuego with the coast of New Guinea on their globes, and allowing their imaginations to run riot in the vast unknown spaces of the south Atlantic, south Indian and Pacific oceans they sketched the outlines of the Terra Australis Incognita ("Unknown Southern Land"), a vast continent stretching in parts into the tropics. The search for this great south land or Third World was a leading motive of explorers in the 16th and the early part of the 17th centuries. In 1599, according to the account of Jacob le Maire, the Dutch Dirck Gerritsz Pomp observed mountainous land at latitude (64°). If so, these were the South Shetland Islands, and possibly the first European sighting of Antarctica (or offshore-lying islands belonging to it). Other accounts, however, do not note this observation, casting doubt on their accuracy. It has been argued that the Spaniard Gabriel de Castilla claimed to have sighted "snow-covered mountains" beyond the 64° S in 1603, but this claim is not generally recognized.

Quirós in 1606 took possession for the king of Spain all of the lands he had discovered in Australia del Espiritu Santo (the New Hebrides) and those he would discover "even to the Pole".

Francis Drake like Spanish explorers before him had speculated that there might be an open channel south of Tierra del Fuego. Indeed, when Schouten and Le Maire discovered the southern extremity of Tierra del Fuego and named it Cape Horn in 1615, they proved that the Tierra del Fuego archipelago was of small extent and not connected to the southern land.

Finally, in 1642 Tasman showed that even New Holland (Australia) was separated by sea from any continuous southern continent. Voyagers round the Horn frequently met with contrary winds and were driven southward into snowy skies and ice-encumbered seas; but so far as can be ascertained none of them before 1770 reached the Antarctic Circle, or knew it, if they did.

The Dutch expedition to Valdivia of 1643 intended to round Cape Horn sailing through Le Maire Strait but strong winds made it instead drift south and east. Northerly winds pushed the expedition as far south as 61°59 S where icebergs were abundant before a southerly wind that begun on April 7 allowed the fleet to advance west. The small fleet led by Hendrik Brouwer managed to enter the Pacific Ocean sailing south of Isla de los Estados disproving earlier beliefs that it was part of Terra Australis.

South of the Antarctic Convergence

The visit to South Georgia by the English merchant Anthony de la Roché in 1675 was the first ever discovery of land south of the Antarctic Convergence. Soon after the voyage cartographers started to depict ‘Roché Island’, honouring the discoverer.

James Cook was aware of la Roché's discovery when surveying and mapping the island in 1775.

Edmond Halley's voyage in HMS Paramour for magnetic investigations in the South Atlantic met the pack ice in 52° S in January 1700, but that latitude (he reached 140 mi off the north coast of South Georgia) was his farthest south. A determined effort on the part of the French naval officer Jean-Baptiste Charles Bouvet de Lozier to discover the "South Land" – described by a half legendary "sieur de Gonneyville" – resulted in the discovery of Bouvet Island in 54°10′ S, and in the navigation of 48° of longitude of ice-cumbered sea nearly in 55° S in 1739.

In 1771, Yves Joseph Kerguelen sailed from France with instructions to proceed south from Mauritius in search of "a very large continent." He lighted upon a land in 50° S which he called South France, and believed to be the central mass of the southern continent. He was sent out again to complete the exploration of the new land, and found it to be only an inhospitable island which he renamed the Isle of Desolation, but which was ultimately named after him.

The Antarctic Circle

James Cook's 1777 south-up map of South Georgia.

The obsession of the undiscovered continent culminated in the brain of Alexander Dalrymple, the brilliant and erratic hydrographer who was nominated by the Royal Society to command the Transit of Venus expedition to Tahiti in 1769. The command of the expedition was given by the admiralty to Captain James Cook. Sailing in 1772 with the Resolution, a vessel of 462 tons under his own command and the Adventure of 336 tons under Captain Tobias Furneaux, Cook first searched in vain for Bouvet Island, then sailed for 20 degrees of longitude to the westward in latitude 58° S, and then 30° eastward for the most part south of 60° S, a higher southern latitude than had ever been voluntarily entered before by any vessel. On 17 January 1773 the Antarctic Circle was crossed for the first time in history and the two ships reached 67° 15' S by 39° 35' E, where their course was stopped by ice.

Cook then turned northward to look for French Southern and Antarctic Lands, of the discovery of which he had received news at Cape Town, but from the rough determination of his longitude by Kerguelen, Cook reached the assigned latitude 10° too far east and did not see it. He turned south again and was stopped by ice in 61° 52′ S by 95° E and continued eastward nearly on the parallel of 60° S to 147° E. On 16 March, the approaching winter drove him northward for rest to New Zealand and the tropical islands of the Pacific. In November 1773, Cook left New Zealand, having parted company with the Adventure, and reached 60° S by 177° W, whence he sailed eastward keeping as far south as the floating ice allowed. The Antarctic Circle was crossed on 20 December and Cook remained south of it for three days, being compelled after reaching 67° 31′ S to stand north again in 135° W.

A long detour to 47° 50′ S served to show that there was no land connection between New Zealand and Tierra del Fuego. Turning south again, Cook crossed the Antarctic Circle for the third time at 109° 30′ W before his progress was once again blocked by ice four days later at 71° 10′ S by 106° 54′ W. This point, reached on 30 January 1774, was the farthest south attained in the 18th century. With a great detour to the east, almost to the coast of South America, the expedition regained Tahiti for refreshment. In November 1774, Cook started from New Zealand and crossed the South Pacific without sighting land between 53° and 57° S to Tierra del Fuego; then, passing Cape Horn on 29 December, he rediscovered Roché Island renaming it Isle of Georgia, and discovered the South Sandwich Islands (named Sandwich Land by him), the only ice-clad land he had seen, before crossing the South Atlantic to the Cape of Good Hope between 55° and 60°. He thereby laid open the way for future Antarctic exploration by exploding the myth of a habitable southern continent. Cook's most southerly discovery of land lay on the temperate side of the 60th parallel, and he convinced himself that if land lay farther south it was practically inaccessible and of no economic value.

First sighting

Admiral Fabian Gottlieb von Bellingshausen was one of the first to spot the continent of Antarctica.

The first land south of the parallel 60° south latitude was discovered by the Englishman William Smith, who sighted Livingston Island on 19 February 1819. He found some remnants and signs of the wreckage of the Spanish ship San Telmo, but to the date it is unknown if any surviving crew members of the San Telmo was landed there. A few months later Smith returned to explore the other islands of the South Shetlands archipelago, landed on King George Island, and claimed the new territories for Britain.

The first confirmed sighting of mainland Antarctica, on 27 January 1820, is attributed to the Russian expedition led by Fabian Gottlieb von Bellingshausen and Mikhail Lazarev, discovering an ice shelf at Princess Martha Coast that later became known as the Fimbul Ice Shelf. Bellingshausen and Lazarev became the first explorers to see and officially discover the land of the continent of Antarctica.

It is certain that the expedition, led by von Bellingshausen and Lazarev on the ships Vostok and Mirny, reached on 28 January 1820 a point within 32 km (20 mi) from Princess Martha Coast and recorded the sight of an ice shelf at 69°21′28″S 2°14′50″W that became known as the Fimbul ice shelf. On 30 January 1820, Edward Bransfield sighted Trinity Peninsula, the northernmost point of the Antarctic mainland. Von Bellingshausen's expedition also discovered Peter I Island and Alexander I Island, the first islands to be discovered south of the circle.

Early exploration

The first landing on the Antarctic mainland is thought to have been made by the American Captain John Davis, a sealer, who claimed to have set foot there on 7 February 1821, though this is not accepted by all historians.

In November 1820, Nathaniel Palmer, an American sealer looking for seal breeding grounds, using maps made by the Loper whaling family, sighted what is now known as the Antarctic Peninsula, located between 55 and 80 degrees west. In 1823, James Weddell, a British sealer, sailed into what is now known as the Weddell Sea. Until the twentieth century, most expeditions were for commercial purpose, to look for the prospects of seal and whale hunting. A piece of wood, from the South Shetland Islands, was the first fossil ever recorded from Antarctica, obtained during a private United States expedition during 1829–31, commanded by Captain Benjamin Pendleton.

Charles Wilkes, as commander of a United States Navy expedition in 1840, discovered what is now known as Wilkes Land, a section of the continent around 120 degrees East.

After the North Magnetic Pole was located in 1831, explorers and scientists began looking for the South Magnetic Pole. One of the explorers, James Clark Ross, a British naval officer, identified its approximate location, but was unable to reach it on his 4 year-expedition from 1839 to 1843. 

Commanding the British ships Erebus and Terror, he braved the pack ice and approached what is now known as the Ross Ice Shelf, a massive floating ice shelf over 100 feet (30 m) high. His expedition sailed eastward along the southern Antarctic coast discovering mountains which were since named after his ships: Mount Erebus, the most active volcano on Antarctica, and Mount Terror.

Map of exploration routes, 1911.

The first documented landing on the mainland of East Antarctica was at Victoria Land by the American sealer Mercator Cooper on 26 January 1853.

These explorers, despite their impressive contributions to South Polar exploration, were unable to penetrate the interior of the continent and, rather, formed a broken line of discovered lands along the coastline of Antarctica. Following the expedition South by the ships Erebus and Terror under James Clark Ross (January, 1841), he suggested that there were no scientific discoveries, or 'problems', worth exploration in the far South. What followed is what historian H.R. Mill called 'the age of averted interest' and in the following twenty years after Ross' return, there was a general lull internationally in Antarctic exploration.

Heroic Age of Antarctic Exploration

The Heroic Age of Antarctic Exploration began at the end of the 19th century and closed with Ernest Shackleton's Imperial Trans-Antarctic Expedition in 1917.

During this period the Antarctic continent became the focus of an international effort that resulted in intensive scientific and geographical exploration and in which 17 major Antarctic expeditions were launched from ten countries.

Origins

Dr. John Murray was the driving force behind the renewal of interest in Antarctic exploration at the beginning of the 20th century.

The initial impetus for the Heroic Age of Antarctic Exploration was a lecture given by Dr. John Murray entitled "The Renewal of Antarctic Exploration", given to the Royal Geographical Society in London, 27 November 1893. Murray advocated that research into the Antarctic should be organised to "resolve the outstanding geographical questions still posed in the south". Furthermore, the Royal Geographical Society instated an Antarctic Committee shortly prior to this, in 1887, which successfully encouraged many whalers to explore the Southern regions of the world and laid the groundwork for the lecture given by Murray.

The Norwegian ship Antarctic was put ashore at Cape Adare, on 24 January 1895.

In August 1895 the Sixth International Geographical Congress in London passed a general resolution calling on scientific societies throughout the world to promote the cause of Antarctic exploration "in whatever ways seem to them most effective". Such work would "bring additions to almost every branch of science". The Congress had been addressed by the Norwegian Carsten Borchgrevink, who had just returned from a whaling expedition during which he had become one of the first to set foot on the Antarctic mainland. During his address, Borchgrevink outlined plans for a full-scale pioneering Antarctic expedition, to be based at Cape Adare.

Adrien de Gerlache, leader of the Belgian expedition.

The Heroic Age was inaugurated by an expedition launched by the Belgian Geographical Society in 1897; Borchgrevink followed a year later with a privately sponsored British expedition. (Some histories consider the Discovery expedition, which departed in 1901, as the first proper expedition of the Heroic Age.)

The Belgian Antarctic Expedition was led by Belgian Adrian de Gerlache. In 1898, they became the first men to spend winter on Antarctica, when their ship Belgica became trapped in the ice. They became stuck on 28 February 1898, and only managed to get out of the ice on 14 March 1899.

During their forced stay, several men lost their sanity, not only because of the Antarctic winter night and the endured hardship, but also because of the language problems between the different nationalities. This was the first expedition to overwinter within the Antarctic Circle, and they visited the South Shetland Islands.

Early British expeditions

RRS Discovery carried an expedition led by Robert Falcon Scott in 1901.

The Southern Cross Expedition began in 1898 and lasted for two years. This was the first expedition to overwinter on the Antarctic mainland (Cape Adare) and was the first to make use of dogs and sledges. It made the first ascent of The Great Ice Barrier, (The Great Ice Barrier later became formally known as the Ross Ice Shelf). The expedition set a Farthest South record at 78°30'S. It also calculated the location of the South Magnetic Pole.

The Discovery Expedition was then launched, from 1901–04 and was led by Robert Falcon Scott. It made the first ascent of the Western Mountains in Victoria Land, and discovered the polar plateau. Its southern journey set a new Farthest South record, 82°17'S. Many other geographical features were discovered, mapped and named. This was the first of several expeditions based in McMurdo Sound.

Jameson Adams, Frank Wild and Eric Marshall (left to right) of the Nimrod Expedition plant the Union flag at their southernmost position.

A year later, the Scottish National Antarctic Expedition was launched, headed by William Speirs Bruce. 'Ormond House' was established as a meteorological observatory on Laurie Island in the South Orkneys and was the first permanent base in Antarctica. The Weddell Sea was penetrated to 74°01'S, and the coastline of Coats Land was discovered, defining the sea's eastern limits.

Ernest Shackleton, who had been a member of Scott's expedition, organized and led the Nimrod Expedition from 1907 to 1909. The expedition's primary objective was of reaching the South Pole. Based in McMurdo Sound, the expedition pioneered the Beardmore Glacier route to the South Pole, and the (limited) use of motorised transport. Its southern march reached 88°23'S, a new Farthest South record 97 geographical miles from the Pole before having to turn back. During the expedition, Shackleton was the first to reach the polar plateau. Parties led by T. W. Edgeworth David also became the first to climb Mount Erebus and to reach the South Magnetic Pole.

Expeditions from other countries

The First German Antarctic Expedition was sent to investigate eastern Antarctica in 1901. It discovered the coast of Kaiser Wilhelm II Land, and Mount Gauss. The expedition's ship became trapped in ice, however, which prevented more extensive exploration.

The Swedish Antarctic Expedition, operating at the same time worked in the east coastal area of Graham Land, and was marooned on Snow Hill Island and Paulet Island in the Weddell Sea, after the sinking of its expedition ship. It was rescued by the Argentinian naval vessel Uruguay.

The French organized their first expedition in 1903 under the leadership of Jean-Baptiste Charcot. Originally intended as a relief expedition for the stranded Nordenskiöld party, the main work of this expedition was the mapping and charting of islands and the western coasts of Graham Land, on the Antarctic peninsula. A section of the coast was explored, and named Loubet Land after the President of France.

A follow up trip was organized from 1908–1910 which continued the earlier work of the French expedition with a general exploration of the Bellingshausen Sea, and the discovery of islands and other features, including Marguerite Bay, Charcot Island, Renaud Island, Mikkelsen Bay, Rothschild Island.

Race to the Pole

Terra Nova bore Robert Falcon Scott and his team on their ill-fated expedition to the South Pole.

The prize of the Heroic age was to reach the South Pole. Two expeditions set off in 1910 to attain this goal; a party led by Norwegian polar explorer Roald Amundsen from the ship Fram and Robert Falcon Scott's British group from the Terra Nova.

Amundsen succeeded in reaching the Pole on 14 December 1911 using a route from the Bay of Whales to the polar plateau via the Axel Heiberg Glacier.

Scott and his four companions reached the South Pole via the Beardmore route on 17 January 1912, 33 days after Amundsen. All five died on the return journey from the Pole, through a combination of starvation and cold. The Amundsen–Scott South Pole Station was later named after these two men.

Further expeditions

The Main Base Hut of the Australasian Antarctic Expedition

The Australasian Antarctic Expedition took place between 1911–1914 and was led by Sir Douglas Mawson. It concentrated on the stretch of Antarctic coastline between Cape Adare and Mount Gauss, carrying out mapping and survey work on coastal and inland territories.

Discoveries included Commonwealth Bay, Ninnis Glacier, Mertz Glacier, and Queen Mary Land. Major accomplishments were made in geology, glaciology and terrestrial biology.

As time wore on it became more and more evident that the ship was doomed by Frank Hurley. (The Endurance trapped in pack ice.)

The Imperial Trans-Antarctic Expedition of 1914–1917 was led by Ernest Shackleton and set out to cross the continent via the South pole. However, their ship, the Endurance, was trapped and crushed by pack ice in the Weddell Sea before they were able to land. The expedition members survived after a journey on sledges over pack ice, a prolonged drift on an ice-floe, and a voyage in three small boats to Elephant Island. Then Shackleton and five others crossed the Southern Ocean in an open boat called James Caird and made the first crossing of South Georgia to raise the alarm at the whaling station Grytviken.

A related component of the Trans-Antarctic Expedition was the Ross Sea party, led by Aeneas Mackintosh. Its objective was to lay depots across the Great Ice Barrier, in order to supply Shackleton's party crossing from the Weddell Sea. All the required depots were laid, but in the process three men, including the leader Mackintosh, lost their lives.

Shackleton's last expedition and the one that brought the 'Heroic Age' to a close, was the Shackleton–Rowett Expedition from 1921–22 on board the ship Quest. Its vaguely defined objectives included coastal mapping, a possible continental circumnavigation, the investigation of sub-Antarctic islands, and oceanographic work. After Shackleton's death on 5 January 1922, Quest completed a shortened programme before returning home.| 

Further exploration

By air

Sir Hubert Wilkins pioneered the exploration of the Arctic regions by aircraft. Pictured, his plane and encampment as part of the Detroit Arctic Expedition, 1926.

After Shackleton's last expedition, there was a hiatus in Antarctic exploration for about seven years. From 1929, aircraft and mechanized transportation were increasingly used, earning this period the sobriquet of the 'Mechanical Age'. Hubert Wilkins first visited Antarctica in 1921–1922 as an ornithologist attached to the Shackleton-Rowett Expedition. From 1927, Wilkins and pilot Carl Ben Eielson began exploring the Arctic by aircraft.

On 15 April 1928, only a year after Charles Lindbergh's flight across the Atlantic, Wilkins and Eielson made a trans-Arctic crossing from Point Barrow, Alaska, to Spitsbergen, arriving about 20 hours later on 16 April, touching along the way at Grant Land on Ellesmere Island. For this feat and his prior work, Wilkins was knighted.

With financial backing from William Randolph Hearst, Wilkins returned to the South Pole and flew over Antarctica in the San Francisco. He named the island of Hearst Land after his sponsor.

US Navy Rear Admiral Richard Evelyn Byrd led five expeditions to Antarctica during the 1930s, 1940s, and 1950s. He overflew the South Pole with pilot Bernt Balchen on 28 and 29 November 1929, to match his overflight of the North Pole in 1926. Byrd's explorations had science as a major objective and extensively used the aircraft to explore the continent.

Captain Finn Ronne, Byrd's executive officer, returned to Antarctica with his own expedition in 1947–1948, with Navy support, three planes, and dogs. Ronne disproved the notion that the continent was divided in two and established that East and West Antarctica was one single continent, i.e. that the Weddell Sea and the Ross Sea are not connected. The expedition explored and mapped large parts of Palmer Land and the Weddell Sea coastline, and identified the Ronne Ice Shelf, named by Ronne after his wife Edith Ronne. Ronne covered 3,600 miles by ski and dog sled—more than any other explorer in history.

Overland crossing

The 1955–58 Commonwealth Trans-Antarctic Expedition successfully completed the first overland crossing of Antarctica, via the South Pole. Although supported by the British and other Commonwealth governments, most of the funding came from corporate and individual donations.

It was headed by British explorer Dr Vivian Fuchs, with New Zealander Sir Edmund Hillary leading the New Zealand Ross Sea Support team. After spending the winter of 1957 at Shackleton Base, Fuchs finally set out on the transcontinental journey in November 1957, with a twelve-man team travelling in six vehicles; three Sno-Cats, two Weasels and one specially adapted Muskeg tractor. En route, the team were also tasked with carrying out scientific research including seismic soundings and gravimetric readings.

In parallel Hillary's team had set up Scott Base – which was to be Fuchs' final destination – on the opposite side of the continent at McMurdo Sound on the Ross Sea. Using three converted Massey Ferguson TE20 tractors and one Weasel (abandoned part-way), Hillary and his three men (Ron Balham, Peter Mulgrew and Murray Ellis), were responsible for route-finding and laying a line of supply depots up the Skelton Glacier and across the Polar Plateau on towards the South Pole, for the use of Fuchs on the final leg of his journey. Other members of Hillary's team carried out geological surveys around the Ross Sea and Victoria Land areas.

Hillary's party reached the South Pole on 3 January 1958, and was just the third (preceded by Amundsen in 1911 and Scott in 1912) to reach the Pole overland. Fuchs' team reached the Pole from the opposite direction on 19 January 1958, where they met up with Hillary. Fuchs then continued overland, following the route that Hillary had laid and on 2 March succeeded in reaching Scott Base, completing the first overland crossing of the continent by land via the South Pole.

Political history

British claims

The United Kingdom reasserted sovereignty over the Falkland Islands in the far South Atlantic in 1833 and maintained a continuous presence there. In 1908, the British government extended its territorial claim by declaring sovereignty over "South Georgia, the South Orkneys, the South Shetlands, and the Sandwich Islands, and Graham's Land, situated in the South Atlantic Ocean and on the Antarctic continent to the south of the 50th parallel of south latitude, and lying between the 20th and the 80th degrees of west longitude". All these territories were administered as Falkland Islands Dependencies from Stanley by the Governor of the Falkland Islands. The motivation for this declaration lay in the need for regulating and taxing the whaling industry effectively. Commercial operators would hunt whales in areas outside of the official boundaries of the Falkland Islands and its dependencies and there was a need to close this loophole.

In 1917, the wording of the claim was modified, so as to, among other things, unambiguously include all the territory in the sector stretching to the South Pole (thus encompassing all of the present-day British Antarctic Territory). The new claim covered "all islands and territories whatsoever between the 20th degree of west longitude and the 50th degree of west longitude which are situated south of the 50th parallel of south latitude; and all islands and territories whatsoever between the 50th degree of west longitude and the 80th degree of west longitude which are situated south of the 58th parallel of south latitude".

Under the ambition of Leopold Amery, the Under-Secretary of State for the Colonies, Britain attempted to incorporate the entire continent into the Empire. In a memorandum to the governor-generals for Australia and New Zealand, he wrote that 'with the exception of Chile and Argentina and some barren islands belonging to France... it is desirable that the whole of the Antarctic should ultimately be included in the British Empire.'

The first step was taken on 30 July 1923, when the British government passed an Order in Council under the British Settlements Act 1887, defining the new borders for the Ross Dependency - "that part of His Majesty's Dominions in the Antarctic Seas, which comprises all the islands and territories between the 160th degree of East Longitude and the 150th degree of West Longitude which are situated south of the 60th degree of South Latitude shall be named the Ross Dependency."

The Order in Council then went on to appoint the Governor-General and Commander-in Chief of New Zealand as the Governor of the territory.

In 1930, the United Kingdom claimed Enderby Land. In 1933, a British imperial order transferred territory south of 60° S and between meridians 160° E and 45° E to Australia as the Australian Antarctic Territory.

Following the passing of the Statute of Westminster in 1931, the government of the United Kingdom relinquished all control over the government of New Zealand and Australia. This however had no bearing on the obligations of the Governor-General of both countries in their capacity as Governor of the Antarctic territories.

Other European claims

Discovery by Jules Dumont d'Urville of Adélie Land in 1840. This served as a basis for the French claim to this region in 1924.

Meanwhile, alarmed by these unilateral declarations, the French government laid claim to a strip of the continent in 1924. The basis for their claim to Adélie Land lay on the discovery of the coastline in 1840 by the French explorer Jules Dumont d'Urville, who named it after his wife, Adèle. The British eventually decided to recognize this claim and the border between Adélie Land and Australian Antarctic Territory was fixed definitively in 1938.

These developments also concerned Norwegian whaling interests, who wished to avoid the British taxation of whaling stations in the Antarctic and were concerned that they would be commercially excluded from the continent. The whale-ship owner Lars Christensen financed several expeditions to the Antarctic with the view to claim land for Norway and establish stations on Norwegian territory to gain better privileges. The first expedition, led by Nils Larsen and Ola Olstad, landed on Peter I Island in 1929 and claimed the island for Norway. On 6 March 1931, a Norwegian royal proclamation declared the island under Norwegian sovereignty and on 23 March 1933 the island was declared a dependency.

The 1929 expedition led by Hjalmar Riiser-Larsen and Finn Lützow-Holm named the continental land mass near the island as Queen Maud Land, named after the Norwegian queen Maud of Wales. The territory was explored further during the Norvegia expedition of 1930–31. Negotiations with the British government in 1938 resulted in the western border of Queen Maud Land being set at 20°W.

Norwegian expedition landing on the Peter I Island in 1929.

Norway's claim was disputed by Nazi Germany, which in 1938 dispatched the German Antarctic Expedition, led by Alfred Ritscher, to fly over as much of it as possible. The ship Schwabenland reached the pack ice off Antarctica on 19 January 1939. During the expedition, an area of about 350,000 square kilometres (140,000 sq mi) was photographed from the air by Ritscher, who dropped darts inscribed with swastikas every 26 kilometres (16 mi). Germany eventually attempted to claim the territory surveyed by Ritscher under the name New Swabia, but lost any claim to the land following its defeat in the Second World War.

On 14 January 1939, five days prior to the German arrival, Queen Maud Land was annexed by Norway, after a royal decree announced that the land bordering the Falkland Islands Dependencies in the west and the Australian Antarctic Dependency in the east was to be brought under Norwegian sovereignty. The primary basis for the annexation was to secure the Norwegian whaling industry's access to the region. In 1948, Norway and the United Kingdom agreed to limit Queen Maud Land to from 20°W to 45°E, and that the Bruce Coast and Coats Land were to be incorporated into Norwegian territory.

South American involvement

Omond House was built in 1904 by the Scottish National Antarctic Expedition as the first permanent base in Antarctica. It was later sold to Argentina.

This encroachment of foreign powers was a matter of immense disquiet to the nearby South American countries, Argentina and Chile. Taking advantage of a European continent plunged into turmoil with the onset of the Second World War, Chile's president, Pedro Aguirre Cerda declared the establishment of a Chilean Antarctic Territory in areas already claimed by Britain.

Argentina had an even longer history of involvement in the Continent. Already in 1904 the Argentine government began a permanent occupation in the area with the purchase of a meteorological station on Laurie Island established in 1903 by Dr William S. Bruce's Scottish National Antarctic Expedition. Bruce offered to transfer the station and instruments for the sum of 5.000 pesos, on the condition that the government committed itself to the continuation of the scientific mission. British officer William Haggard also sent a note to the Argentine Foreign Minister, Jose Terry, ratifying the terms of Bruce proposition.

In 1906, Argentina communicated to the international community the establishment of a permanent base on South Orkney Islands. However, Haggard responded by reminding Argentina that the South Orkneys were British. The British position was that Argentine personnel was granted permission only for the period of one year. The Argentine government entered into negotiations with the British in 1913 over the possible transfer of the island. Although these talks were unsuccessful, Argentina attempted to unilaterally establish their sovereignty with the erection of markers, national flags and other symbols.  Finally, with British attention elsewhere, Argentina declared the establishment of Argentine Antarctica in 1943, claiming territory that overlapped with British ( 20°W to 80°W) and the earlier Chilean (53°W to 90°W) claims.

In response to this and earlier German explorations, the British Admiralty and Colonial Office launched Operation Tabarin in 1943 to reassert British territorial claims against Argentine and Chilean incursion and establish a permanent British presence in the Antarctic. The move was also motivated by concerns within the Foreign Office about the direction of United States post-war activity in the region.

A suitable cover story was the need to deny use of the area to the enemy. The Kriegsmarine was known to use remote islands as rendezvous points and as shelters for commerce raiders, U-boats and supply ships. Also, in 1941, there existed a fear that Japan might attempt to seize the Falkland Islands, either as a base or to hand them over to Argentina, thus gaining political advantage for the Axis and denying their use to Britain.

In 1943, British personnel from HMS Carnarvon Castle removed Argentine flags from Deception Island. The expedition was led by Lieutenant James Marr and left the Falkland Islands in two ships, HMS William Scoresby (a minesweeping trawler) and Fitzroy, on Saturday 29 January 1944.

Bases were established during February near the abandoned Norwegian whaling station on Deception Island, where the Union Flag was hoisted in place of Argentine flags, and at Port Lockroy (on February 11) on the coast of Graham Land. A further base was founded at Hope Bay on 13 February 1945, after a failed attempt to unload stores on 7 February 1944. Symbols of British sovereignty, including post offices, signposts and plaques were also constructed and postage stamps were issued.

Operation Tabarin provoked Chile to organize its First Chilean Antarctic Expedition in 1947–48, where the Chilean president Gabriel González Videla personally inaugurated one of its bases.

Following the end of the war in 1945, the British bases were handed over to civilian members of the newly created Falkland Islands Dependencies Survey (subsequently the British Antarctic Survey) the first such national scientific body to be established in Antarctica.

Post war developments

Hut built at Hope Bay in 1903. It was there that the only instance of shots fired in anger on the Continent occurred in 1952.

Friction between Britain and the Latin American states continued into the post war period. Royal Navy warships were despatched in 1948 to prevent naval incursions and in 1952, an Argentine shore party at Hope Bay (the British Base "D", established there in 1945, came up against the Argentine Esperanza Base, est. 1952) fired a machine gun over the heads of a British Antarctic Survey team unloading supplies from the John Biscoe. The Argentines later extended a diplomatic apology, saying that there had been a misunderstanding and that the Argentine military commander on the ground had exceeded his authority.

The United States became politically interested in the Antarctic continent before and during WWII. The United States Antarctic Service Expedition, from 1939–1941, was sponsored by the government with additional support came from donations and gifts by private citizens, corporations and institutions. The objectives of the Expedition, outlined by President Franklin D. Roosevelt, was to establish two bases: East Base, in the vicinity of Charcot Island, and West Base, in the vicinity of King Edward VII Land. After operating successfully for two years, but with international tensions on the rise, it was considered wise to evacuate the two bases.

However, immediately after the war, American interest was rekindled with an explicitly geopolitical motive. Operation Highjump, from 1946–1947 was organized by Rear Admiral Richard E. Byrd Jr. and included 4,700 men, 13 ships, and multiple aircraft. The primary mission of Operation Highjump was to establish the Antarctic research base Little America IV, for the purpose of training personnel and testing equipment in frigid conditions and amplifying existing stores of knowledge of hydrographic, geographic, geological, meteorological and electromagnetic propagation conditions in the area. The mission was also aimed at consolidating and extending United States sovereignty over the largest practicable area of the Antarctic continent, although this was publicly denied as a goal even before the expedition ended.

Towards an international treaty

The International Geophysical Year was pivotal in establishing a cooperative international framework in Antarctica, and led on to the Antarctic Treaty System in 1959.

Meanwhile, in an attempt at ending the impasse, Britain submitted an application to the International Court of Justice in 1955 to adjudicate between the territorial claims of Britain, Argentina and Chile. This proposal failed, as both Latin American countries rejected submitting to an international arbitration procedure.

Negotiations towards the establishment of an international condominium over the continent first began in 1948, involving the 7 claimant powers (Britain, Australia, New Zealand, France, Norway, Chile and Argentina) and the US. This attempt was aimed at excluding the Soviet Union from the affairs of the continent and rapidly fell apart when the USSR declared an interest in the region, refused to recognize any claims of sovereignty and reserved the right to make its own claims in 1950.

An important impetus toward the formation of the Antarctic Treaty System in 1959, was the International Geophysical Year, 1957–1958. This year of international scientific cooperation triggered an 18-month period of intense Antarctic science. More than 70 existing national scientific organizations then formed IGY committees, and participated in the cooperative effort. The British established Halley Research Station in 1956 by an expedition from the Royal Society. Sir Vivian Fuchs headed the Commonwealth Trans-Antarctic Expedition, which completed the first overland crossing of Antarctica in 1958. In Japan, the Japan Maritime Safety Agency offered ice breaker Sōya as the South Pole observation ship and Showa Station was built as the first Japanese observation base on Antarctica.

France contributed with Dumont d'Urville Station and Charcot Station in Adélie Land. The ship Commandant Charcot of the French Navy spent nine months of 1949/50 at the coast of Adelie Land, performing ionospheric soundings. The US erected the Amundsen–Scott South Pole Station as the first permanent structure directly over the South Pole in January 1957.

Finally, to prevent the possibility of military conflict in the region, the United States, United Kingdom, the Soviet Union and 9 other countries with significant interests negotiated and signed the Antarctic Treaty in 1959. The treaty entered into force in 1961 and sets aside Antarctica as a scientific preserve, established freedom of scientific investigation and banned military activity on that continent. The treaty was the first arms control agreement established during the Cold War.

Recent history

MV Explorer in Antarctica in January 1999. She sank on 23 November 2007 after hitting an iceberg.

A baby, named Emilio Marcos de Palma, was born near Hope Bay on 7 January 1978, becoming the first baby born on the continent. He also was born farther south than anyone in history.

On 28 November 1979, an Air New Zealand DC-10 on a sightseeing trip crashed into Mount Erebus on Ross Island, killing all 257 people on board.

In 1991 a convention among member nations of the Antarctic Treaty on how to regulate mining and drilling was proposed. Australian Prime Minister Bob Hawke and French Prime Minister Michel Rocard led a response to this convention that resulted in the adoption of the Protocol on Environmental Protection to the Antarctic Treaty, now known as the Madrid Protocol. All mineral extraction was banned for 50 years and the Antarctic was set aside as a "natural reserve, devoted to peace and science".

Børge Ousland, a Norwegian explorer, finished the first unassisted Antarctic solo crossing on 18 January 1997.

On 23 November 2007, the MV Explorer struck an iceberg and sank, but all on board were rescued by nearby ships, including a passing Norwegian cruise ship, the MS Nordnorge.

Women in Antarctica

First women at the South Pole are Pam Young, Jean Pearson, Lois Jones, Eileen McSaveney, Kay Lindsay and Terry Tickhill.

Women were originally kept from exploring Antarctica until well into the 1950s. A few pioneering women visited the Antarctic land and waters prior to the 1950s and many women requested to go on early expeditions, but were turned away. Early pioneers such as Louise Séguin and Ingrid Christensen were some of the first women to see Antarctic waters. Christensen was the first woman to set foot on the mainland of Antarctica. The first women to have any fanfare about their Antarctic journeys were Caroline Mikkelsen who set foot on an island of Antarctica in 1935, and Jackie Ronne and Jennie Darlington who were the first women to over-winter in Antarctica in 1947. The first woman scientist to work in Antarctica was Maria Klenova in 1956. Silvia Morella de Palma was the first woman to give birth in Antarctica, delivering 3.4 kg (7 lb 8 oz) Emilio Palma at the Argentine Esperanza base 7 January 1978.

Women faced legal barriers and sexism that prevented most from visiting Antarctica and doing research until the late 1960s. The United States Congress banned American women from traveling to Antarctica until 1969. Women were often excluded because it was thought that they could not handle the extreme temperatures or crisis situations. The first woman from the British Antarctic Survey to go to Antarctica was Janet Thomson in 1983 who described the ban on women as a "rather improper segregation."

Once women were allowed in Antarctica, they still had to fight against sexism and sexual harassment. However, a tipping point was reached in the mid 1990s when it became the new normal that women were part of Antarctic life. Women began to see a change as more and more women began working and researching in Antarctica.
