This is a list of events occurring in Antarctica in 2012.
The geography of Antarctica is dominated by its south polar location and, thus, by ice. The Antarctic continent, located in the Earth's southern hemisphere, is centered asymmetrically around the South Pole and largely south of the Antarctic Circle. It is washed by the Southern Ocean or, depending on definition, the southern Pacific, Atlantic, and Indian Oceans. It has an area of more than 14.2 million km2. Antarctica is the largest ice desert in the world.
Lake Vostok is the largest of Antarctica's 675 known subglacial lakes. Lake Vostok is located at the southern Pole of Cold, beneath Russia's Vostok Station under the surface of the central East Antarctic Ice Sheet, which is at 3,488 m (11,444 ft) above mean sea level. The surface of this fresh water lake is approximately 4,000 m (13,100 ft) under the surface of the ice, which places it at approximately 500 m (1,600 ft) below sea level.
The Amundsen Sea is an arm of the Southern Ocean off Marie Byrd Land in western Antarctica. It lies between Cape Flying Fish to the east and Cape Dart on Siple Island to the west. Cape Flying Fish marks the boundary between the Amundsen Sea and the Bellingshausen Sea. West of Cape Dart there is no named marginal sea of the Southern Ocean between the Amundsen and Ross Seas. The Norwegian expedition of 1928–1929 under Captain Nils Larsen named the body of water for the Norwegian polar explorer Roald Amundsen while exploring this area in February 1929.
Elephant Island is an ice-covered, mountainous island off the coast of Antarctica in the outer reaches of the South Shetland Islands, in the Southern Ocean. The island is situated 245 kilometres north-northeast of the tip of the Antarctic Peninsula, 1,253 kilometres west-southwest of South Georgia, 935 kilometres south of the Falkland Islands, and 885 kilometres southeast of Cape Horn. It is within the Antarctic claims of Argentina, Chile and the United Kingdom.
A subglacial lake is a lake that is found under a glacier, typically beneath an ice cap or ice sheet. Subglacial lakes form at the boundary between ice and the underlying bedrock, where gravitational pressure decreases the pressure melting point of ice. Over time, the overlying ice gradually melts at a rate of a few millimeters per year. Meltwater flows from regions of high to low hydraulic pressure under the ice and pools, creating a body of liquid water that can be isolated from the external environment for millions of years.
Denman Glacier is a glacier 11 to 16 km wide, descending north some 110 km (70 mi), which debouches into the Shackleton Ice Shelf east of David Island, Queen Mary Land. It was discovered in November 1912 by the Western Base party of the Australasian Antarctic Expedition under Sir Douglas Mawson. Mawson named the glacier for Lord Denman, Governor-General of Australia in 1911, a patron of the expedition.
Pine Island Glacier (PIG) is a large ice stream, and the fastest melting glacier in Antarctica, responsible for about 25% of Antarctica's ice loss. The glacier ice streams flow west-northwest along the south side of the Hudson Mountains into Pine Island Bay, Amundsen Sea, Antarctica. It was mapped by the United States Geological Survey (USGS) from surveys and United States Navy (USN) air photos, 1960–66, and named by the Advisory Committee on Antarctic Names (US-ACAN) in association with Pine Island Bay.
Lake Ellsworth is a natural freshwater liquid subglacial lake located in West Antarctica under approximately 3.4 km (2.1 mi) of ice. It is approximately 10 km long and is estimated to be 150 m (490 ft) in depth. The lake is named after the American explorer Lincoln Ellsworth. The surface of the lake itself is located over 4,593 feet (1,400 m) below sea level.
Inexpressible Island is a small, rocky island in Terra Nova Bay, Victoria Land, Antarctica. Previously uninhabited, the Chinese Qinling research station on the southern edge of the island became operational in 2024.
The Nisshin Maru (日新丸) was the primary vessel of the Japanese whaling fleet and was the world's only whaler factory ship. It was the research base ship for the Institute of Cetacean Research for 2002 to 2007. It had a tonnage of 8,145 GT and is the largest member and flagship of the five-ship whaling fleet, headed by leader Shigetoshi Nishiwaki. The ship was based in Japan in Shimonoseki harbor and was owned by Tokyo-based Kyodo Senpaku, which is a subsidiary of the Institute of Cetacean Research.
Events from the year 2007 in Antarctica
Antarctica is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14,200,000 km2 (5,500,000 sq mi). Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km (1.2 mi).
Whale Wars is a weekly American documentary-style reality television series that premiered on November 7, 2008 on the Animal Planet cable channel. The program follows Paul Watson, founder of the Sea Shepherd Conservation Society, as he and the crew aboard their various vessels attempted to stop the killing of whales by Japanese vessels (whalers) off the coast of Antarctica.
The Sea Shepherd Conservation Society engages in various demonstrations, campaigns, and tactical operations at sea and elsewhere, including conventional protests and direct actions to protect marine wildlife. Sea Shepherd operations have included interdiction against commercial fishing, shark poaching and finning, seal hunting and whaling. Many of their activities have been called piracy or terrorism by their targets and by the ICRW. Sea Shepherd says that they have taken more than 4,000 volunteers on operations over a period of 30 years.
There are hundreds of antarctic lakes in Antarctica. In 2018 researchers at the Alfred Wegener Institute for Polar and Marine Research published a study they claimed cast doubt on the earlier estimate that there were almost 400 subglacial antarctic lakes. Antarctica also has some relatively small regions that are clear of ice and snow, and there are some surface lakes in these regions. They called for on the ground seismic studies, or drilling, to determine a more reliable number.
The Brazilian Antarctic Program is a program of the Brazilian Navy which has presence in the continent of Antarctica. It coordinates research and the operational support for research in the region. It currently maintains a year-round research station in Antarctica, as well as several seasonal field camps. It also maintains two research vessels that sail in the Antarctic waters.
Jemma L Wadham is a British glacial biogeochemist.
Robin Elizabeth Bell is Palisades Geophysical Institute (PGI) Lamont Research Professor at Columbia University's Lamont–Doherty Earth Observatory and a past President of the American Geophysical Union (AGU), 2019–2021. Dr. Bell was influential in co-ordinating the 2007 International Polar Year and was the first woman to chair the National Academy of Sciences Polar Research Board. She has made numerous important discoveries with regard to subglacial lakes and ice sheet dynamics, and has a ridge, called Bell Buttress, in Antarctica named after her.
Martin J. Siegert is a British glaciologist, and Deputy Vice Chancellor (Cornwall) at the University of Exeter. He co-Chairs the Diversity in Polar Science Initiative, and has spoken about socio-economic inclusion in Polar Science and indeed broader society.
Sun Laurel is a South Korean-owned oil tanker built in 2008 and currently operating under the flag of Vanuatu.
