Dålk Glacier
Dålk Glacier () is a glacier, long, draining into the southeast part of Prydz Bay between the Larsemann Hills and Steinnes. It was mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition (1936–37), and named by John H. Roscoe in his 1952 study of features in the area as identified in air photos taken by U.S. Navy Operation Highjump (1946–47). It was named after Dålk Island lying at the terminus of the glacier.

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 ...

Prydz Bay
Prydz Bay is a deep embayment of Antarctica between the Lars Christensen Coast and Ingrid Christensen Coast. The Bay is at the downstream end of a giant glacial drainage system that originates in the East Antarctic interior. The Lambert Glacier flows from Lambert Graben into the Amery Ice Shelf on the south-west side of Prydz Bay. Other major glaciers drain into the southern end of the Amery Ice Shelf at 73° S where the marine part of the system starts at the modern grounding zone. The Amery Ice Shelf extends about 550 km north of the Lambert Glacier grounding zone and occupies a valley between 80 and 200 km wide. Depths to the bed beneath the Amery Ice Shelf are poorly known in detail but it is clearly over-deepened, reaching around -2500 m MSL close to the grounding zone. The Amery Ice Shelf occupies a very large U-shaped valley with exposed nunataks along the flanks reaching 1500 m in elevation and total relief as high as 3000 m. Seaward of the Amery Ice She ...

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 ...

Larsemann Hills
The Larsemann Hills are a series of low rounded coastal hills along the southeastern shore of Prydz Bay, Antarctica extending for from Dålk Glacier. They were discovered in February 1935 by Captain Klarius Mikkelsen from the whaling ship ''Thorshavn'', sent out by Norwegian whaling magnate Lars Christensen, and given this name. The bedrock of the Larsemann Hills contains an unusually high abundance of boron and phosphate minerals and is the location of discovery of four new species of mineral. In 2014, the Stornes Peninsula within the Larsemann Hills was declared an Antarctic Specially Protected Area due to its mineral diversity. Research stations As an Antarctic oasis the hills are the home of several Antarctic research stations. * The abandoned original Russian Progress Station. * The relocated new Russian Progress II Station. * The Chinese Zhongshan station * The Australian-donated Romanian Law-Racoviță-Negoiță Station * The India India, officially the ...

Lars is a common male name in Scandinavian countries. Origin ''Lars'' means "from the city of Laurentum". Lars is derived from the Latin name Laurentius, which means "from Laurentum" or "crowned with laurel", and is therefore related to the name Laurence and Lauren. A homonymous Etruscan name was borne by several Etruscan kings, and later used as a last name by the Roman Lartia family. The etymology of the Etruscan name is unknown.

List Of Glaciers In The Antarctic
There are many glaciers in the Antarctic. This set of lists does not include ice sheets, ice caps or ice fields, such as the Antarctic ice sheet, but includes glacial features that are defined by their flow, rather than general bodies of ice. The lists include outlet glaciers, valley glaciers, cirque glaciers, tidewater glaciers and ice streams. Ice streams are a type of glacier and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined as any latitude further south than 60° (the continental limit according to the Antarctic Treaty System).

Glaciology
Glaciology (; ) is the scientific study of glaciers, or, more generally, ice and natural phenomena that involve ice. Glaciology is an interdisciplinary Earth science that integrates geophysics, geology, physical geography, geomorphology, climatology, meteorology, hydrology, biology, and ecology. The impact of glaciers on people includes the fields of human geography and anthropology. The discoveries of water ice on the Moon, Mars, Europa (moon), Europa and Pluto add an extraterrestrial component to the field, which is referred to as "astroglaciology". Overview A glacier is a persistent body of dense ice, a form of rock) formed from snow falling and accumulating over a long period of time; glaciers move very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of accumulation, as in continental glaciers. Areas of study within glaciology include glacial history and the reconstruction of past glaciation. A glaciologist is a person ...
