ANTARCTICA


Welcome to Antarctica

History of the exploration of Antarctica:


350 B.C.
It was the ancient Greeks who first came up with the idea of Antarctica. They knew about the Arctic - named Arktos - The Bear, from the constellation the great bear and decided that in order to balance the world, there should be a similar cold Southern landmass that was the same but the opposite "Ant - Arktos" - opposite The Bear. They never actually went there, it was just a lucky guess!
Did anyone see a continent around here?
1773

In January, James Cook crosses the Antarctic circle and circumnavigates Antarctica, though he doesn't sight land, deposits of rock seen in icebergs showed that a southern continent exists. His comment - "I make bold to declare that the world will derive no benefit from it".

1819 - 21

You can see our house from here.Captain Thaddeus Bellingshausen a Russian naval officer in the Vostok and Mirny circumnavigates the Antarctic, first to cross the Antarctic circle since Cook.

He made the first sighting of the continent, reaching 69° 21'S, 2° 14'W - describing an "icefield covered with small hillocks." on Jan 27th 1820.

For some considerable time, exactly who and when first set eyes on Antarctica were in dispute as British naval officers, William Smith and Edward Bransfield also saw Antarctica on Jan 30th the same year - followed by American sealer Nathaniel Palmer on Nov 16th.

This was the first time a continent had truly been "discovered" (i.e. there weren't any native peoples living there who'd known about it for ages already). All sightings are of the Antarctic Peninsula.

1821

Antarctic exploration was bad news for seals.February the 7th. 1st known landing on continental Antarctica by American sealer Captain John Davis, though this is not acknowledged by all historians.

In the winter of 1821, for the first time ever a party of men spent a winter in Antarctica. An officer and ten men from a British sealing ship the Lord Melville had to spend the winter on King George Island - part of the South Shetlands group, north of the Antarctic Peninsula. The ship had been driven offshore and did not return to pick them up again. They were rescued the following summer.

1823

Whales weren't keen on Antarctica being explored eitherBritish whaler James Weddell discovers the sea named after him and then reaches the most southerly point at that time 74° 15' S. No one else manages to penetrate the Weddell sea again for 80 years.

1840's

Separate British, French and American expeditions establish the status of Antarctica as a continent after sailing along continuous coastline.

In 1840, British naval officer and scientist James Clark Ross takes two ships, the Erebus and the Terror, to within 80 miles of the coast until stopped by a massive ice barrier - now called the Ross Ice Shelf. He also discovers the active volcano that he names after his ship Erebus, and identifies 145 new species of fish (not personally you understand - a scientist on the ship did that bit).


Late 1800's to early 20th century. Many expeditions largely by sealers and whalers to all parts of Antarctica. Mainly marine exploration and exploration of the sub Antarctic islands.
 Oh, a life on the ocean wave.......

1898

March. Adrien de Gerlache and the crew of the "Belgica" become trapped in pack ice off the Antarctic Peninsula in the first scientific expedition to the continent. They become the first to survive an Antarctic winter (involuntarily!) as their ship drifts with the ice (they didn't enjoy it).


1899

Carsten Borchgrevink leads a British expedition that landed men at Cape Adare and built huts. This was the first time that anyone had wintered on the Antarctic landmass. Believed by some historians to be the first confirmed landing on continental Antarctica.

1902

Captain Scott, UK, leads his first Antarctic expedition to reach the South Pole, with Ernest Shackleton and Edward Wilson. They are forced to turn back two months later having reached 82 degrees south, suffering from snow blindness and scurvy.


Several other publicly and privately sponsored expeditions around this time. By now, these are driven by science, geography and exploration - less by the exploitation of resources such as seals and whales.
If we sail over there, we'll see some particularly fine plankton...

1907 - 1909

Shackleton leads expedition to within 156km / 97mls of the South Pole, turns back after supplies are exhausted.

1909

January, Australian Douglas Mawson reaches the South Magnetic Pole.

1911

Missed the sledge again!!December 14th. Norwegian Roald Amundsen leads a five man expedition that reaches the South Pole for the first time.

1912

Scott and his men manhauled all of the way to the pole and back againJanuary 18th. Britain's Captain Robert Falcon Scott reaches the South Pole to discover he has been beaten by Amundsen. All of the five man team (Scott, Bowers, Evans, Oates and Wilson), are to perish on the return journey only 11 miles from supply depot. Bodies are not discovered until November.

December. Douglas Mawson begins his trek across George V Land back to his base at Commonwealth Bay. His two companions had died, and against the odds he makes it home. A new section of coast is discovered and described, and radio is used for the first time in Antarctica.

1915

October. Shackleton returns to Antarctica in an attempt to complete the first crossing of the continent. The goal is not attained, but one of the greatest adventures of all time follows. Their ship is crushed in the sea ice and a small party sets out for South Georgia and the whaling station. The party is eventually rescued in 1917.

1923.

The beginning of large-scale factory ship whaling in the Ross Sea.

Fly over the white bit again, I liked that.1928

Australian Sir George Wilkins and American Carl Benjamin Eielson are the first to fly over Antarctica around the peninsula region.

1929

Richard E. Byrd and three others - US - become the first to fly over the South Pole.

1935

Lincoln Ellsworth - US - flies across the continent.

Caroline Mikkelsen, Norway,  is the first woman to set foot on Antarctica when she accompanies her husband, a whaling captain.

1947

Operation Highjump - US - sends the largest ever expedition of over 4700 men, 13 ships and 23 airplanes to Antarctica. Most of the coast is photographed for map making.

1956

US aircraft lands at South Pole. First people there since Scott and his team in 1912.

1st July 1957 - 31st Dec 1958

International Geophysical Year (IGY) 12 nations establish over 60 stations in Antarctica. The beginning of international cooperation in Antarctica and the start of the process by which Antarctica becomes "non-national".

The first successful land crossing via the South Pole is led by British geologist Vivian Fuchs with New Zealander Edmund Hillary leading the back up party, over 40 years after Shackleton's expedition set out with the same aim.

1961

Antarctic treaty comes into effect:

1997

Boerge Ousland (Norway) becomes first person to cross Antarctica unsupported. Taking 64 days from Berkner Island to Scott base towing a 180kg (400lb) sled and using skis and a sail.

March 2007 - March 2009

International Polar Year - Actually Spans two years in order that researchers get the opportunity to work in both polar regions or work summer and winter if they wish.
