The Antarctic is a polar region around Earth's South Pole, opposite the Arctic region around the North Pole.
Lake Vostok is the largest of Antarctica's almost 400 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 Ross Sea is a deep bay of the Southern Ocean in Antarctica, between Victoria Land and Marie Byrd Land and within the Ross Embayment, and is the southernmost sea on Earth. It derives its name from the British explorer James Clark Ross who visited this area in 1841. To the west of the sea lies Ross Island and Victoria Land, to the east Roosevelt Island and Edward VII Peninsula in Marie Byrd Land, while the southernmost part is covered by the Ross Ice Shelf, and is about 200 miles (320 km) from the South Pole. Its boundaries and area have been defined by the New Zealand National Institute of Water and Atmospheric Research as having an area of 637,000 square kilometres (246,000 sq mi).
The United States Antarctic Program is an organization of the United States government which has a presence in the Antarctica continent. Founded in 1959, the USAP manages all U.S. scientific research and related logistics in Antarctica as well as aboard ships in the Southern Ocean.
The Scientific Committee on Antarctic Research (SCAR) is an interdisciplinary body of the International Science Council (ISC). SCAR coordinates international scientific research efforts in Antarctica, including the Southern Ocean.
The Antarctic and Southern Ocean Coalition (ASOC) is a global coalition of environmental non-governmental organizations with more than 150 members in 40 countries worldwide. ASOC has worked since 1978 to ensure that the Antarctic Continent, its surrounding islands and the great Southern Ocean survive as the world's last unspoiled wilderness, a global commons for the heritage of future generations. ASOC is supported entirely through donations from individual supporters around the world, dues from its members and grants from foundations. The Secretariat of the Antarctic and Southern Ocean Coalition (ASOC), which includes 150 organizations in 40 countries, is based in Washington, D.C. The ASOC Council includes member groups that have paid dues or provided significant in-kind services to the ASOC campaign team.
Dame Jane Elizabeth Francis, is the Director of the British Antarctic Survey. She previously worked as Professor of Palaeoclimatology at the University of Leeds where she also was Dean of the Faculty of Environment. In 2002 she was the fourth woman to receive the Polar Medal for outstanding contribution to British polar research. She is currently the Chancellor of the University of Leeds.
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).
Dissostichus, the toothfish, is a genus of marine ray-finned fish belonging to the family Nototheniidae, the notothens or cod icefish. These fish are found in the Southern Hemisphere. Toothfish are marketed in the United States as Chilean sea bass or less frequently as white cod. "Chilean sea bass" is a marketing name coined in 1977 by Lee Lantz, a fish wholesaler who wanted a more attractive name for selling the Patagonian toothfish to Americans. In 1994, the U.S. Food and Drug Administration (FDA) accepted "Chilean sea bass" as an "alternative market name" for Patagonian toothfish. The toothfish was remarkably successful in the United States, Europe and Asia, and earned the nickname "white gold" within the market. Toothfish are vital to the ecological structure of Southern Ocean ecosystems. For this reason, on 4 September a national day is dedicated to the toothfish in South Georgia.
Catherine C. "Cath" Wallace is a New Zealand environmentalist and academic. She is a lecturer in economics and public policy at Victoria University of Wellington, and has been active in environment organizations in New Zealand. She was awarded the Goldman Environmental Prize in 1991, for her contributions to the protection of the environment of Antarctica.
Temperature change due to climate change in Antarctica is not stable over the whole continent. West Antarctica is warming rapidly, while the inland regions are cooled by the winds in Antarctica. Water in the West Antarctic has warmed by 1 °C since year 1955. Further increase in temperature in water and on land will affect the climate, ice mass and life on the continent and have global implications. Present-day greenhouse gas concentrations are higher than ever according to ice cores from Antarctica, which indicates that warming on this continent is not part of a natural cycle and attributable to anthropogenic climate change.
Helen Amanda Fricker is a glaciologist and professor at Scripps Institution of Oceanography at the University of California, San Diego where she is a director of the Scripps Polar Center. She won the 2010 Martha T. Muse Prize for Science and Policy in Antarctica.
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.
Angelika Brandt is the world leader in Antarctic deep-sea biodiversity and has developed, organised and led several oceanographic expeditions to Antarctica, notably the series of ANDEEP cruises, which have contributed significantly to Antarctica and deep-sea biology. Brandt was the senior scientist of ANDEEP which was devoted entirely to benthic research in the Antarctic abyss.
Barbara Wienecke is a senior research scientist with the Australian Antarctic Division. She is a seabird ecologist who uses satellite tracking to investigate seabird population dynamics and ecology. Wienecke has played a key role in enhancing the quality of, and overseeing the implementation of, a number of Antarctic Specially Protected Area management plans for wildlife concentrations in East Antarctica.

Polly A. Penhale is an American biologist and Environmental Officer at the National Science Foundation. She is a leading figure in Antarctic research, and has been recognized for contributions to research, policy, and environmental conservation. Penhale Peak in Antarctica is named for her.
The Antarctic gateway cities are five cities on the rim of the Southern Ocean through which nearly all cargo and personnel bound for Antarctica pass. From west to east, they are Punta Arenas, Chile; Ushuaia, Argentina; Cape Town, South Africa; Hobart, Australia; and Christchurch, New Zealand. As Antarctica is a low-resource environment with no major transportation infrastructure of its own, gateway cities are a necessary part of all Antarctic activities.
