4. South Pole of Inaccessibility

The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is one of the two points where the Earth's axis of rotation intersects its surface. It is the southernmost point on the surface of the Earth and lies on the opposite side of the Earth from the North Pole. Situated on the continent of Antarctica, it is the site of the United States Amundsen-Scott South Pole Station, which was established in 1956 and has been permanently staffed since that year. The Geographic South Pole should not be confused with the South Magnetic Pole, which though geographically nearby, is defined based on the Earth's magnetic field.

Geography[link]

The Geographic South Pole

The Ceremonial South Pole

For most purposes, the Geographic South Pole is defined as the southern point of the two points where the Earth's axis of rotation intersects its surface (the other being the Geographic North Pole). However, the Earth's axis of rotation is actually subject to very small 'wobbles', so this definition is not adequate for very precise work; see Polar Motion for further information.

The geographic coordinates of the South Pole are usually given simply as 90°S, since its longitude is geometrically undefined and irrelevant. When a longitude is desired, it may be given as 0°. At the South Pole all directions face north. For this reason, directions at the Pole are given relative to "grid north", which points northwards along the prime meridian.^[1]

The Geographic South Pole is located on the continent of Antarctica (although this has not been the case for all of Earth's history because of continental drift). It sits atop a featureless, windswept, icy plateau at an altitude of 2,835 metres (9,301 ft), about 1,300 km (800 mi) from the nearest open sea at Bay of Whales. The ice is estimated to be about 2,700 metres (9,000 ft) thick at the Pole, so the land surface under the ice sheet is actually near sea level.^[2]

The polar ice sheet is moving at a rate of roughly 10 metres per year in a direction between 37° and 40° west of grid north,^[3] down towards the Weddell Sea. Therefore, the position of the station and other artificial features relative to the geographic pole gradually shifts over time.

The Geographic South Pole is marked by a small sign and a stake in the ice pack, which are repositioned each year on New Year's Day to compensate for the movement of the ice.^[4] The sign records the respective dates that Roald Amundsen and Robert F. Scott reached the Pole, followed by a short quotation from each man, and gives the elevation as 9,301 ft (2,835 m).^[5][6]

Ceremonial South Pole[link]

The Ceremonial South Pole is an area set aside for photo opportunities at the South Pole Station. It is located a short distance from the Geographic South Pole, and consists of a metallic sphere on a plinth, surrounded by the flags of the Antarctic Treaty signatory states.

Pre-1900[link]

In 1820, several expeditions claimed to have been the first to have sighted Antarctica, with the very first being the Russian expedition led by Faddey Bellingshausen and Mikhail Lazarev. The first landing was probably just over a year later when American Captain John Davis, a sealer, set foot on the ice.

The basic geography of the Antarctic coastline was not understood until the mid-to-late 19th century. American naval officer Charles Wilkes claimed (correctly) that Antarctica was a new continent based on his exploration in 1839–40,^[7] while James Clark Ross, in his expedition of 1839–43, hoped that he might be able to sail all the way to the South Pole (he was unsuccessful).^[8]

1900–1950[link]

The first attempt to find a route from the Antarctic coastline to the South Pole was made by British explorer Robert Falcon Scott on the Discovery Expedition of 1901–04. Scott, accompanied by Ernest Shackleton and Edward Wilson, set out with the aim of travelling as far south as possible, and on 31 December 1902, reached 82°16′ S.^[9] Shackleton later returned to Antarctica as leader of the British Antarctic Expedition (Nimrod Expedition) in a bid to reach the Pole. On 9 January 1909, with three companions, he reached 88°23′ S – 112 statute miles from the Pole – before being forced to turn back.^[10]

The first humans to reach the Geographic South Pole were Norwegian Roald Amundsen and his party on December 14, 1911. Amundsen named his camp Polheim and the entire plateau surrounding the Pole King Haakon VII Vidde in honour of King Haakon VII of Norway. Robert Falcon Scott had also returned to Antarctica with his second expedition, the Terra Nova Expedition, in a race against Amundsen to the Pole. Scott and four other men reached the South Pole on January 17, 1912, thirty-four days after Amundsen. On the return trip, Scott and his four companions all died of starvation and extreme cold.

In 1914 Ernest Shackleton's Imperial Trans-Antarctic Expedition set out with the goal of crossing Antarctica via the South Pole, but his ship, the Endurance, was frozen in pack-ice and sank 11 months later. The overland journey was never made.

US Admiral Richard Evelyn Byrd, with the assistance of his first pilot Bernt Balchen, became the first person to fly over the South Pole on November 29, 1928.

1950–present[link]

Amundsen-Scott South Pole Station. The ceremonial pole and flags can be seen in the background, slightly to the left of centre, below the tracks behind the buildings. The actual geographic pole is a few more metres to the left. The buildings are raised on stilts to prevent snow build up.

It was not until 31 October 1956 that humans once again set foot at the South Pole, when a party led by Admiral George J. Dufek of the US Navy landed there in an R4D-5L Skytrain (C-47 Skytrain) aircraft. The US Amundsen-Scott South Pole Station was established by air over 1956–1957 for the International Geophysical Year and has been continuously staffed since then by research and support personnel.^[2]

After Amundsen and Scott, the next people to reach the South Pole overland (albeit with some air support) were Edmund Hillary (January 4, 1958) and Vivian Fuchs (January 19, 1958) and their respective parties, during the Commonwealth Trans-Antarctic Expedition. There have been many subsequent expeditions to arrive at the South Pole by surface transportation, including those by Havola, Crary and Fiennes.

Subsequent to the establishment, in 1987, of the logistic support base at Patriot Hills, the South Pole became more accessible to non government expeditions.

On December 30, 1989, Arved Fuchs and Reinhold Messner were the first to traverse Antarctica via the South Pole without animal or motorised help, using only skis and the help of wind.^[11][12]

The fastest unsupported journey to the Geographic South Pole from the ocean is 24 days and one hour from Hercules Inlet and was set in 2011 by Norwegian adventurer Christian Eide,^[13] who beat the previous solo record set in 2009 by American Todd Carmichael of 39 days and seven hours, and the previous group record also set in 2009 of 33 days and 23 hours.^[14]

Climate, and day and night[link]

See also Climate of Antarctica, Midnight sun and Polar night

During the southern winter (March–September), the South Pole receives no sunlight at all, and from May to July, between extended periods of twilight, it is completely dark (apart from moonlight). In the summer (September–March), the sun is continuously above the horizon and appears to move in an anti-clockwise circle. However, it is always low in the sky, reaching a maximum of 23.5° in December. Much of the sunlight that does reach the surface is reflected by the white snow. This lack of warmth from the sun, combined with the high altitude (about 2,800 metres (9,186 ft)), means that the South Pole has one of the coldest climates on Earth (though it is not quite the coldest; that record goes to the region in the vicinity of the Vostok Station, also in Antarctica, which lies at a higher elevation).^[15] Temperatures at the South Pole are much lower than at the North Pole, primarily because the South Pole is located at altitude in the middle of a continental land mass, while the North Pole is at sea level in the middle of an ocean (which acts as a reservoir of heat).

In midsummer, as the sun reaches its maximum elevation of about 23.5 degrees, high temperatures at the South Pole in January average at −25.9 °C (−15 °F). As the six-month "day" wears on and the sun gets lower, temperatures drop as well: they reach −45 °C (−49 °F) around sunset (late March) and sunrise (late September). In winter, the average temperature remains steady at around −58 °C (−72 °F). The highest temperature ever recorded at the Amundsen-Scott South Pole Station was −12.3 °C (9.9 °F) on December 25, 2011,^[16] and the lowest was −82.8 °C (−117.0 °F) on June 23, 1982^[17][18][19] (the lowest recorded anywhere on earth was −89.2 °C (−128.6 °F) at Vostok Station on July 21, 1983).

The South Pole has a desert climate, almost never receiving any precipitation. Air humidity is near zero. However, high winds can cause the blowing of snowfall, and the accumulation of snow amounts to about 20 cm (7.9 in) per year.^[20] The dome seen in pictures of the Amundsen-Scott station is partially buried due to snow storms, and the entrance to the dome has to be regularly bulldozed to uncover it. More recent buildings are raised on stilts so that the snow does not build up against the sides of them.

Time[link]

In most places on Earth, local time is determined by longitude, such that the time of day is more-or-less synchronised to the position of the sun in the sky (for example, at midday the sun is roughly at its highest). This line of reasoning fails at the South Pole, where the sun rises and sets only once per year, and all lines of longitude, and hence all time zones, converge. There is no a priori reason for placing the South Pole in any particular time zone, but as a matter of practical convenience the Amundsen-Scott South Pole Station keeps New Zealand Time. This is because the US flies its resupply missions ("Operation Deep Freeze") out of McMurdo Station which is supplied from Christchurch, New Zealand.

Flora and fauna[link]

Due to its exceptionally harsh climate, there are no native resident plants or animals at the South Pole. Remarkably, though, off-course skuas are occasionally seen there.^[23]

In 2000 it was reported that microbes had been detected living in the South Pole ice, though scientists think it is unlikely that they evolved in Antarctica.^[24]

According to a 2012 report, "the polar ice sheets are now known to be a gigantic reservoir of microbial life, trapped longer than modern humans have walked the planet".^[25]

Roald Engelbregt Gravning Amundsen (Norwegian pronunciation: [ˈɾuːɑl ˈɑmʉnsən]; 16 July 1872 – c. 18 June 1928) was a Norwegian explorer of polar regions. He led the Antarctic expedition (1910-12) to discover the South Pole in December 1911 and he was the first expedition leader to (undisputedly) reach the North Pole in 1926.^[1][2] He is also known as the first to traverse the Northwest Passage (1903-06). He disappeared in June 1928 while taking part in a rescue mission. Amundsen, along with Douglas Mawson, Robert Falcon Scott, and Ernest Shackleton, was a key expedition leader during the Heroic Age of Antarctic Exploration.

Early life[link]

Roald Amundsen as a young boy in Christiania, 1875

Amundsen was born to a family of Norwegian shipowners and captains in Borge, between the towns Fredrikstad and Sarpsborg. His father was Jens Amundsen. He was the fourth son in the family. His mother chose to keep him out of the maritime industry of the family and pressured him to become a doctor, a promise that Amundsen kept until his mother died when he was aged 21, whereupon he quit university for a life at sea.^[3] Amundsen had hidden a lifelong desire inspired by Fridtjof Nansen's crossing of Greenland in 1888 and the doomed Franklin expedition. As a result, he decided on a life of intense exploration.^{[citation needed]}

Polar treks[link]

Belgian Antarctic Expedition (1897–99)[link]

Portraits of Roald Amundsen

He was a member of the Belgian Antarctic Expedition (1897–99) as first mate. This expedition, led by Adrien de Gerlache using the ship the Belgica, became the first expedition to winter in Antarctica.^[4] 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 then endured a winter for which the expedition was poorly prepared. By Amundsen's own estimation, the doctor for the expedition, American Frederick Cook, probably saved the crew from scurvy by hunting for animals and feeding the crew fresh meat, an important lesson for Amundsen's future expeditions.

Northwest Passage (1903–1906)[link]

"Belgica" frozen in the ice, 1898

In 1903, Amundsen led the first expedition to successfully traverse Canada's Northwest Passage between the Atlantic and Pacific Oceans (something explorers had been attempting since the days of Christopher Columbus, John Cabot, Jacques Cartier, and Henry Hudson), with six others in a 47-ton steel seal-hunting vessel, Gjøa. Amundsen had the ship outfitted with a small gasoline engine.^[5] They travelled via Baffin Bay, Lancaster and Peel Sounds, and James Ross, Simpson and Rae Straits and spent two winters near King William Island in what is today Gjoa Haven, Nunavut, Canada.^[4][5]

During this time Amundsen learned from the local Netsilik people about Arctic survival skills that would later prove useful. For example, he learned to use sled dogs and to wear animal skins in lieu of heavy, woolen parkas. After a third winter trapped in the ice, Amundsen was able to navigate a passage into the Beaufort Sea after which he cleared into the Bering Strait, thus having successfully navigated the Northwest Passage.^[3] Continuing to the south of Victoria Island, the ship cleared the Canadian Arctic Archipelago on 17 August 1905, but had to stop for the winter before going on to Nome on the Alaska District's Pacific coast. Five hundred miles (800 km) away, Eagle City, Alaska, had a telegraph station; Amundsen travelled there (and back) overland to wire a success message (collect) on 5 December 1905. Nome was reached in 1906. Because the water along the route was as shallow as 3 ft (0.91 m), a larger ship could not have made the voyage.^{[citation needed]}

It was at this time that Amundsen received news that Norway had formally become independent of Sweden and had a new king. Amundsen sent the new King Haakon VII news that it "was a great achievement for Norway". He said he hoped to do more and signed it "Your loyal subject, Roald Amundsen."^{[citation needed]}

South Pole Expedition (1910–12)[link]

After crossing the Northwest Passage, Amundsen made plans to go to the North Pole and explore the North Polar Basin. Amundsen had problems and hesitation raising funds for the departure and upon hearing in 1909 that first Frederick Cook and then Robert Peary claimed the Pole, he decided to reroute to Antarctica.^[6] However, he did not make these plans known and misled both the Englishman, Robert F. Scott and the Norwegians.^[6] Using the ship Fram ("Forward"), earlier used by Fridtjof Nansen, he left Norway for the south, leaving Oslo on 3 June 1910.^[6][7] At Madeira, Amundsen alerted his men that they would be heading to Antarctica in addition to sending a telegram to Scott notifying him simply: "BEG TO INFORM YOU FRAM PROCEEDING ANTARCTIC--AMUNDSEN."^[6] 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, where Amundsen located his base camp and named it Framheim. Further, Amundsen eschewed the heavy wool clothing worn on earlier Antarctic attempts in favour of Eskimo-style skins.^[3]

Roald Amundsen

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.^[3] Amundsen also planned to kill some of his dogs on the way and use them as a source for fresh meat. A premature attempt, which included Hjalmar Johansen, Kristian Prestrud and Jørgen Stubberud, set out on 8 September 1911, but had to be abandoned due to extreme temperatures. The painful retreat caused a tempering quarrel within the group, with the result that Johansen and others were sent to explore King Edward VII Land.

A second attempt with a team, consisting of Olav Bjaaland, Helmer Hanssen, Sverre Hassel, Oscar Wisting, and Amundsen himself, departed on 19 October 1911. 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. On 14 December 1911, the team of five, with 16 dogs, arrived at the Pole (90° 0′ S).^{[n 1]} They arrived 33–34 days before Scott’s group. Amundsen named their South Pole camp Polheim, "Home on the Pole." 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 returned to Framheim on 25 January 1912, with 11 dogs. Amundsen’s success was publicly announced on 7 March 1912, when he arrived at Hobart, Australia.

Amundsen’s expedition benefited from careful preparation, good equipment, appropriate clothing, a simple primary task (Amundsen did no surveying on his route south and is known to have taken only two photographs), 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 rather smooth and uneventful.

In Amundsen’s own words:

I may say that this is the greatest factor—the way in which the expedition is equipped—the way in which every difficulty is foreseen, and precautions taken for meeting or avoiding it. Victory awaits him who has everything in order — luck, people call it. Defeat is certain for him who has neglected to take the necessary precautions in time; this is called bad luck.

— from The South Pole, by Roald Amundsen

Amundsen wrote about the expedition in The South Pole: an account of the Norwegian Antarctic Expedition in the "Fram", 1910–12, published in 1912.

Northeast Passage (1918–1920)[link]

The Polarship Maud in June 1918

In 1918, Amundsen began an expedition with a new ship Maud, which was to last until 1925. Maud sailed West to East through the Northeast Passage, now called the Northern Route (1918–1920).

With him on this expedition were Oscar Wisting and Helmer Hanssen, both of whom had accompanied Amundsen to the South Pole. In addition, Henrik Lindstrøm was included as a cook, but he suffered a stroke and was so physically reduced that he could not participate.

The aim of the expedition was to explore the unknown areas of the Arctic Ocean, strongly inspired by Fridtjof Nansen's expedition earlier 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 expedition had a clear academic profile, with 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. Unfortunately, the ice became so thick that the ship was unable to break free, even though the ship was designed specifically for such a journey. In September 1919, the ship came loose from the ice, but froze again after a mere eleven days somewhere between the New Siberian Islands and Wrangel Island.

During this time, Amundsen participated little in the work outdoors, such as sleigh rides and hunting, because he had been subjected to numerous accidents. He had a broken arm and had been attacked by polar bears. Hanssen and Wisting, along with two others, embarked on an expedition by dog sled to Nome, Alaska, despite its being over one thousand kilometres away. But the ice was not frozen solid in the Bering Strait and it could not be crossed. They were, at the very least, able to send a telegram from Anadyr.

After two winters frozen in the ice without having achieved the goal of drifting over the North Pole, Amundsen decided to go to Nome himself to repair the ship and buy provisions. There were several of the crew ashore there, including Hanssen, who had not returned to the ship. Amundsen considered him to be in breach of contract, and as such, dismissed him from the crew.

The third winter saw Maud frozen in the western Bering Strait, before finally reaching Seattle for repairs in 1921. Amundsen now returned to Norway, spurred by a need to put his finances in order. He brought with him two indigenous girls, the adopted four-year-old Kakonita and her companion Camilla. When he went bankrupt two years later, however, they were dispatched to Camilla's father in Russia.^[10]

Amundsen returned to Maud, which now lay in Nome, in June 1922. He moved the focus from naval expeditions to aerial expeditions, and therefore arranged to get a plane. The expedition was divided into two: one part was to survive the winter to get ready for an attempt to fly over the pole. This part was led by Amundsen. 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, before it was finally seized by Amundsen's creditors as collateral for the debt he had incurred.

The attempt to fly over the Pole failed, too. Amundsen and Oskar Omdal, of the Royal Norwegian Navy, attempted to fly from Wainwright, Alaska, to Spitsbergen across the North Pole. Their aircraft was damaged, and they abandoned the journey. To raise additional funds, Amundsen travelled 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, were of considerable value. Many of these carefully collected scientific data had been lost during the ill-fated journey of Peter Tessem and Paul Knutsen, two crew members sent on a mission by Amundsen, but they were later retrieved by Russian scientist Nikolay Urvantsev as they lay abandoned on the Kara Sea shores.^[11]

Reaching the North Pole[link]

In 1925, accompanied by Lincoln Ellsworth, pilot Hjalmar Riiser-Larsen, and three 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. One, the N-24 was damaged. Amundsen and his crew worked for over 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, 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 Spitzbergen on 11 May 1926, and they landed in Alaska two days later. The three previous claims to have arrived at the North Pole—by Frederick Cook in 1908; Robert Peary in 1909; and Richard Evelyn Byrd in 1926 (just a few days before the Norge)—are all disputed, as being either of dubious accuracy or outright fraud.^[12][13] If their claims are false, the crew of the Norge would be the first verified explorers to have reached the North Pole. If the Norge expedition was actually the first to the North Pole, Amundsen and Oscar Wisting would therefore be the first persons to reach each geographical pole, by ground or by air, as the case may be.

Disappearance and death[link]

Amundsen monument in Ny-Ålesund, Svalbard, Norway

Amundsen disappeared on 18 June 1928 while flying on a rescue mission with Norwegian pilot Leif Dietrichson, French pilot René Guilbaud, and three more Frenchmen, looking for missing members of Nobile's crew, whose new airship Italia had crashed while returning from the North Pole. Afterwards, a wing-float and bottom gasoline tank from the French Latham 47 flying boat he was in, improvised into a replacement wing-float, was found near the Tromsø coast. It is believed that the plane crashed in fog in the Barents Sea, and that Amundsen was killed in the crash, or died shortly afterwards. His body was never found. The search for Amundsen was called off in September by the Norwegian Government. In 2003 it was suggested that the plane went down northwest of Bear Island.^{[citation needed]}

In 2004 and in late August 2009 unsuccessful searches were made by the Royal Norwegian Navy for the wreckage of Amundsen's plane, using the unmanned submarine Hugin 1000. The searches focused on a 40-square-mile (100 km²) area of the sea floor, and were documented by the German production company ContextTV.^[14][15]
