The Lars Christensen Coast is that portion of the coast of Antarctica lying between Murray Monolith, in 66°54′E, and the head of the Amery Ice Shelf in 71°0′E. The seaward portions of this area (along the Amery Ice Front to Murray Monolith) were discovered and sailed along by Norwegian whalers employed by Lars Christensen of Sandefjord, Norway for whom this coast is named. Christensen personally participated in some of the exploration conducted in Antarctica by his firm, 1926–37. Exploration and mapping of the southwestern (interior) side of the Amery Ice Shelf was accomplished by Australian expeditions during the 1950s. [1]

Antarctica Polar continent in the Earths southern hemisphere

Antarctica is Earth's southernmost continent. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,200,000 square kilometres, it is the fifth-largest continent. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.

Murray Monolith is a detached part of Torlyn Mountain in Mac.Robertson Land, Antarctica. It was discovered during the British Australian New Zealand Antarctic Research Expedition (BANZARE), led by Mawson, 1929–1931, and named after Sir George Murray, Chancellor of the University of Adelaide and a patron of the expedition.

Amery Ice Shelf ice shelf in Antarctica

The Amery Ice Shelf is a broad ice shelf in Antarctica at the head of Prydz Bay between the Lars Christensen Coast and Ingrid Christensen Coast. It is part of Mac. Robertson Land. The name "Cape Amery" was applied to a coastal angle mapped on February 11, 1931 by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Douglas Mawson. He named it for William Bankes Amery, a civil servant who represented the United Kingdom government in Australia (1925–28). The Advisory Committee on Antarctic Names interpreted this feature to be a portion of an ice shelf and, in 1947, applied the name Amery to the whole shelf.

Prydz Bay 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 systems 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.

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.

Polar Times Glacier glacier in Antarctica

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.

The Leopold and Astrid Coast is that portion of the coast of Antarctica lying between the western extremity of the West Ice Shelf, at 81°24′E, and Cape Penck, at 87°43′E. It is located in the eastern half of Princess Elizabeth Land. It was discovered and explored in an airplane flight from the Norwegian ship Thorshavn on January 17, 1934, by Lieutenant Alf Gunnestad and Captain Nils Larsen. The coast was named by Lars Christensen, Norwegian whaling magnate and leader of the expedition, for King Leopold and Queen Astrid of Belgium.

The Mawson Coast is that portion of the coast of Mac. Robertson Land, Antarctica, lying between William Scoresby Bay, at 59°34′E, and Murray Monolith, at 66°54′E. The coast was sighted during the British Australian New Zealand Antarctic Research Expedition (BANZARE), 1929–30, under Sir Douglas Mawson. Further exploration and landings at Cape Bruce and Scullin Monolith were made during BANZARE, 1930–31. Mawson Coast was named by the Antarctic Names Committee of Australia after Mawson in recognition of his great contribution to Antarctic exploration.

Framnes Mountains

The Framnes Mountains are an Antarctic mountain range consisting of Casey Range, Masson Range, David Range, and Brown Range, and adjacent peaks and mountains. The three major ranges and other lesser features were sighted and named in February 1931 by the British Australian New Zealand Antarctic Research Expedition under Douglas Mawson. This coast was also sighted by Norwegian whalers in the same season. The whole area was mapped in detail by Norwegian cartographers from aerial photographs taken by the Lars Christensen Expedition in January 1937. This overall name for the several ranges was given by Lars Christensen after Framnesfjellet, a hill near Sandefjord, Norway.

Seaton Glacier glacier in Antarctica

Seaton Glacier is a glacier 17 miles (27 km) long, flowing southeast into Edward VIII Ice Shelf at the northwest part of Edward VIII Bay. It was mapped by Norwegian cartographers from aerial photos taken by the Lars Christensen Expedition, 1936–37, remapped, 1954–58, by ANARE and named by ANCA in 1958 for Flight Lt. John Seaton, RAAF, pilot with ANARE at Mawson in 1956.

It was mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition (1936–37), and named by John H. Roscoe in a 1952 study of U.S. Navy Operation Highjump aerial photography of this coast. The name alludes to the jumbled, chaotic, appearance of the terminal glacial flowage.

The Flatnes Ice Tongue is an ice tongue forming the western limit of Amanda Bay in the south-east part of Prydz Bay, Ingrid Christensen Coast, Princess Elizabeth Land, Antarctica. The tongue is nourished by local drainage and extends for 6 kilometres (4 mi) into the bay. It was plotted by Norwegian cartographers from aerial photographs taken by the Lars Christensen Expedition of 1936–37 and named Flatnes. The generic term "ice tongue" has been approved for this feature on the basis of John H. Roscoe's 1952 study of features in the area as identified in air photos taken by the US Navy's Operation Highjump (1946–47).

Hariot Glacier is a glacier flowing northwest along the south side of Morgan Upland before turning west into the northern portion of the Wordie Ice Shelf, along the west coast of the Antarctic Peninsula. It was roughly surveyed by the British Graham Land Expedition, 1936–37, and the upper reaches were photographed from the air by the Ronne Antarctic Research Expedition, 1947.
