Polar Times Glacier
Polar Times Glacier () is a glacier on Ingrid Christensen Coast, flowing northward between Svarthausen Nunatak and Boyd Nunatak into the western part of Publications Ice Shelf. It was delineated by John H. Roscoe from aerial photographs taken by USN Operation Highjump, 1946–1947, and named by Roscoe after The Polar Times, a polar journal published by the American Polar Society, New York City.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual Climate of Antarctica#Precipitation, precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the Lowest temperature recorded on Earth, lowest measured temperature on Earth, . The coastal regions can reach temperatures over in the ...

Princess Elizabeth Land
Princess Elizabeth Land is the sector of Antarctica between longitude 73rd meridian east, 73° east and Cape Penck (at 87°43' east). The sector is claimed by Australia as part of the Australian Antarctic Territory, although this claim is not widely recognised. Geography Princess Elizabeth Land is located between 64°56'S and South Pole, 90°00'S and between 73°35' E and 87°43'E. It is divided into two sectors: * Ingrid Christensen Coast, 73°35'E to 81°24'E * Leopold and Astrid Coast, 81°24'E to 87°43'E It is bounded on the west by Amery Ice Shelf, Mac. Robertson Land, and on the east by Kaiser Wilhelm II Land. Exploration Princess Elizabeth Land was discovered on 9 February 1931, by the British Australian and New Zealand Antarctic Research Expedition (BANZARE) (1929–31) under Sir Douglas Mawson. Princess Elizabeth Land was named by Mawson after Elizabeth II, Princess Elizabeth, granddaughter of King George V who reigned at the time as King of Australia, among his othe ...

Publications Ice Shelf
Publications Ice Shelf is an Antarctic ice shelf about 35 nautical miles (60 km) long on the south shore of Prydz Bay, between Mount Caroline Mikkelsen and Stornes Peninsula. Several glaciers, listed from southwest to northeast, nourish the ice shelf: Polar Times Glacier, Il Polo Glacier, Polarforschung Glacier, Polar Record Glacier and Polararboken Glacier. The feature was first mapped from air photos by the Lars Christensen Expedition, 1936–37. The name "Publication Glacier Tongues" was applied by John H. Roscoe in 1952 following his study of U.S. Navy Operation Highjump Operation HIGHJUMP, officially titled The United States Navy Antarctic Developments Program, 1946–1947, (also called Task Force 68), was a United States Navy (USN) operation to establish the Antarctic research base Little America (exploration b ...

Glacier
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land“Glacier, N., Pronunciation.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115. Accessed 25 Jan. 2025. and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on ever ...

Ingrid Christensen Coast
The Ingrid Christensen Coast is that portion of the coast of Antarctica lying between Jennings Promontory, in 72°33′E, and the western end of the West Ice Shelf in 81°24′E. It is located in the western half of Princess Elizabeth Land, just east of the Amery Ice Shelf. Exploration The coast was discovered and a landing made on the Vestfold Hills on February 20, 1935, by Captain Klarius Mikkelsen in the ''Tórshavn'', a vessel owned by Norwegian whaling magnate Lars Christensen. It was named for Ingrid Christensen, wife of Lars, who sailed in Antarctic waters with her husband, and was one of the first women to visit Antarctica. The southwestern portion of this coast was discovered and photographed from the air by U.S. Navy Operation Highjump Operation HIGHJUMP, officially titled The United States Navy Antarctic Developments Program, 1946–1947, (also called Task Force 68), was a United States Navy (USN) operation to establish the Antarctic research base Little America (e ...

Svarthausen Nunatak
Svarthausen Nunatak () is a jagged, dark rock nunatak with a small outlier to the southwest, lying on the west side of Polar Times Glacier, about 4 nautical miles (7 km) south-southeast of Mount Caroline Mikkelsen.
