Vinson Massif is a large mountain massif in Antarctica that is 21 km (13 mi) long and 13 km (8 mi) wide and lies within the Sentinel Range of the Ellsworth Mountains. It overlooks the Ronne Ice Shelf near the base of the Antarctic Peninsula. The massif is located about 1,200 kilometres (750 mi) from the South Pole. Vinson Massif was discovered in January 1958 by U.S. Navy aircraft. In 1961, the Vinson Massif was named by the Advisory Committee on Antarctic Names (US-ACAN), after Carl G. Vinson, United States congressman from the state of Georgia, for his support for Antarctic exploration. On November 1, 2006, US-ACAN declared Mount Vinson and Vinson Massif to be separate entities. Vinson Massif lies within the Chilean claim under the Antarctic Treaty System.
The Advisory Committee on Antarctic Names is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica.
The Royal Society Range is a mountain range in Victoria Land, Antarctica. With its summit at 4,025 metres (13,205 ft), the massive Mount Lister forms the highest point in this range. Mount Lister is located along the western shore of McMurdo Sound between the Koettlitz, Skelton and Ferrar glaciers. Other notable local terrain features include Allison Glacier, which descends from the west slopes of the Royal Society Range into Skelton Glacier.
Smith Glacier is a low-gradient Antarctic glacier, over 160 km (100 mi) long, draining from Toney Mountain in an ENE direction to Amundsen Sea. A northern distributary, Kohler Glacier, drains to Dotson Ice Shelf but the main flow passes to the sea between Bear Peninsula and Mount Murphy, terminating at Crosson Ice Shelf.
The Usarp Mountains are a major Antarctic mountain range, lying west of the Rennick Glacier and trending north to south for about 190 kilometres (118 mi). The feature is bounded to the north by Pryor Glacier and the Wilson Hills.
Thwaites Glacier, nicknamed the Doomsday Glacier, is an unusually broad and vast Antarctic glacier flowing into Pine Island Bay, part of the Amundsen Sea, east of Mount Murphy, on the Walgreen Coast of Marie Byrd Land. Its surface speeds exceed 2 kilometres per year near its grounding line. Its fastest-flowing grounded ice is centered between 50 and 100 kilometres east of Mount Murphy. In 1967, the Advisory Committee on Antarctic Names named the glacier after Fredrik T. Thwaites (1883–1961), a glacial geologist, geomorphologist and professor emeritus at the University of Wisconsin–Madison.
Explorers Range is a large mountain range in the Bowers Mountains of Victoria Land, Antarctica, extending from Mount Bruce in the north to Carryer Glacier and McLin Glacier in the south. Named by the New Zealand Antarctic Place-Names Committee (NZ-APC) for the northern party of New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1963–64, whose members carried out a topographical and geological survey of the area. The names of several party members are assigned to features in and about this range. All of the geographical features listed below lie situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
Nichols Ridge is a rock ridge between Denton Glacier and Decker Glacier in east Asgard Range, Victoria Land. The feature descends from heights north of Mount Newall to the snout of Wright Lower Glacier at the east end of Wright Valley. Named by Advisory Committee on Antarctic Names (US-ACAN) (1997) after Robert L. Nichols, one of the first American scientists to do geologic research in Wright Valley. In 1958, he found pecten deposits near the middle of the valley that greatly heightened research to determine the origin of the deposits and the glacial history of Wright Valley. This ridge is in proximity to Meserve, Hart, Goodspeed, and Denton Glaciers, named after four young geologists who worked in this area under Nichols in the 1958-59 field season.
Sullivan Heights is a compact group of mountains in western Antarctica rising to 2,760 m (9,060 ft) in Mount Levack centered 11.5 nautical miles east-northeast of Mount Tyree in the Sentinel Range, Ellsworth Mountains. Roughly elliptical in plan and 11 nautical miles long, the feature includes sharp mountain peaks, rugged ridges, and steep peripheral scarps. The heights are encompassed by the flow of the Crosswell, Ellen, and Dater Glaciers, with their interior drained also by Pulpudeva and Strinava Glaciers. Separated from Vinson Massif to the south-southwest by Vranya Pass.
Solomon Glacier is a glacier on the south side of Fisher Bastion which flows west from Solomon Saddle to enter Potter Glacier in the Royal Society Range, Victoria Land. Named by Advisory Committee on Antarctic Names (US-ACAN) in 1994 after Susan Solomon, NOAA, atmospheric chemist who has been a leader in the study of upper atmospheric physics in Antarctica. At the time of naming, Chairman of the Office of Polar Programs Advisory Committee, National Science Foundation (NSF).
Severinghaus Glacier is a glacier flowing southwestward from Karnare Col along the north side of Mount Strybing and the south side of Mount Craddock into Bender Glacier in southern Sentinel Range, Ellsworth Mountains in Antarctica. Named by the US-ACAN (2006) after Jeffrey P. Severinghaus, University of Rhode Island Graduate School of Oceanography; USAP researcher from 1996 on the history of the atmosphere, including greenhouse gases, and history of climate changes, using the ice core record.
Bender Glacier is a glacier that flows from Mount Atkinson and Mount Craddock southwards between Chaplin Peak and Krusha Peak, and joins Nimitz Glacier just south of Gilbert Spur in the southern Sentinel Range, Ellsworth Mountains in Antarctica. Receiving ice influx from its left tributaries Severinghaus Glacier, Brook Glacier and Bolgrad Glacier.
Saltzman Glacier is a glacier that drains the north slopes of Mount Allen, the east slopes of Mount Strybing and Karnare Col, and the southeast slopes of Mount Craddock, and flows eastwards between Mount Osborne and Moyher Ridge into Thomas Glacier in southern Sentinel Range, Ellsworth Mountains in Antarctica.
Cervellati Glacier is the 5 nmi long glacier situated southeast of Patton Glacier and northwest of Ramorino Glacier on the east slope of Sentinel Range in the Ellsworth Mountains, Antarctica. It flows northeastwards between Tyree Ridge and Epperly Ridge, and enters Crosswell Glacier southeast of Mount Bearskin. The feature was named by US-ACAN in 2006 after Roberto Cervellati, Italian representative to the SCAR Expert Group on Geographic Information, 1992–2006, and director of the SCAR Composite Gazetteer of Antarctica in the same period.
Della Pia Glacier is a glacier that descends the east slope of Craddock Massif and flows between Mount Mohl and Elfring Peak into Thomas Glacier in the Sentinel Range, Ellsworth Mountains in Antarctica.
Chaplin Peak is the peak rising to 1978 m on the west side of Bender Glacier, 5 mi southwest of Mount Craddock and 1.3 miles north of Gilbert Spur in the Sentinel Range of Ellsworth Mountains, Antarctica. Surmounting Nimitz Glacier to the west.
Thwaites Ice Shelf, is an Antarctic ice shelf in the Amundsen Sea. It was named by ACAN after Fredrik T. Thwaites, a glacial geologist and geomorphologist. The Thwaites Ice Shelf is one of the biggest ice shelves in West Antarctica, though it is highly unstable and disintegrating rapidly. Since the 1980s, the Thwaites glacier, nicknamed the "Doomsday glacier", has had a net loss of over 600 billion tons of ice, though pinning of the Thwaites Ice Shelf has served to slow the process. The Thwaites Ice Shelf has acted like a dam for the eastern portion of glacier, bracing it and allowing for a slow melt rate, in contrast to the undefended western portion.
Jane Kathryn Willenbring is an American geomorphologist and professor at Stanford University. She is best known for using cosmogenic nuclides to investigate landscape changes and dynamics. She has won multiple awards including the Antarctica Service Medal and the National Science Foundation CAREER Award.
Picture a Scientist is a 2020 documentary highlighting gender inequality in science. The movie tells the stories of several prominent female researchers, and brings to light the barriers they encountered, including cases of discrimination and harassment. The movie features MIT's professor of biology Nancy Hopkins, the chemist Raychelle Burks and the geoscientist Jane Willenbring, among other scientists.
David R. Marchant is an American glacial geologist and former professor at Boston University. Prior to working at Boston University, Marchant worked at the University of Maine. His approach to glaciology has been described as "stabilism," someone who believes that the East Antarctic Ice Sheet has remained cold and generally stable for the past 15 million years. In 1994, an Antarctic glacier was named after him.
