Argentine Antarctica is a sector of Antarctica claimed by Argentina as part of its national territory consisting of the Antarctic Peninsula and a triangular section extending to the South Pole, delimited by the 25° West and 74° West meridians and the 60° South parallel. This region overlaps with British and Chilean claims in Antarctica; however, all claims are suspended by the Antarctic Treaty System, of which Argentina is a founding signatory and permanent consulting member, with the Antarctic Treaty Secretariat being based in Buenos Aires.
Weertman Island is the largest and southernmost of the Bennett Islands, lying in Hanusse Bay. It was mapped from air photos taken by Ronne Antarctic Research Expedition (RARE) (1947–48) and Falkland Islands and Dependencies Aerial Survey Expedition (FIDASE) (1956–57), and named by United Kingdom Antarctic Place-Names Committee (UK-APC) for Johannes Weertman, American metallurgist who proposed a theory of slip of glaciers on their beds and has made important contributions to the theory of glacier flow.
Aitkenhead Glacier is a 10-mile (16 km) long glacier flowing east-southeast from the Detroit Plateau, Graham Land, into Prince Gustav Channel. It was mapped from surveys by the Falkland Islands Dependencies Survey (FIDS) (1960–61), and named by the United Kingdom Antarctic Place-Names Committee for Neil Aitkenhead, a FIDS geologist at Hope Bay (1959–60).
Prevot Island is a small rocky island 0.5 nautical miles (0.9 km) northeast of Miller Island, forming the northernmost of the Wauwermans Islands, in the Wilhelm Archipelago. The name was approved by the Argentine geographic coordinating committee in 1956, replacing the provisional toponym "Fernando." Named in memory of First Lieutenant Prevot, commander of the mobile detachment in the operations of the Argentine Air Force unit for Antarctica. He died on active duty.
Blanchard Glacier is a glacier flowing into Wilhelmina Bay between Garnerin Point and Sadler Point, on the west coast of Graham Land. First charted by the Belgian Antarctic Expedition under Gerlache, 1897–99, it was named by the UK Antarctic Place-Names Committee in 1960 for Jean-Pierre Blanchard (1753–1809), French aeronaut, the first professional balloon pilot, who, with John Jeffries, made the first balloon crossing of the English Channel in 1785.
Brown Island in the Antarctic is a small, brown, almost snow-free island in the southeastern part of the Wauwermans Islands, 2 nautical miles (4 km) southwest of Wednesday Island, in the Wilhelm Archipelago. It was charted by the British Graham Land Expedition under John Rymill, 1934–37, and so named because its brown color distinguished it from adjacent snow-capped islands.
Nimrod Passage is a marine passage leading to the northern end of Lemaire Channel between Wauwermans Islands and Dannebrog Islands in Wilhelm Archipelago. Surveyed by the Royal Navy Hydrographic Survey Unit in March–April 1964, and safely navigated by RRS John Biscoe at this time. Named after the motor survey boat Nimrod which was used to take most of the soundings.
Wheatstone Glacier is a glacier on the west coast of Graham Land. It enters Errera Channel east of Danco Island. Charted by the Belgian Antarctic Expedition under Gerlache, 1897-99. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 for Sir Charles Wheatstone (1802–75), English scientist and inventor who designed the first mirror stereoscope in 1832.
Swan Rock is a low rock lying 1.5 nautical miles (2.8 km) southwest of Cape Willems, off the west coast of Graham Land. The rock appears on an Argentine government chart of 1950. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 for Sir Joseph Swan (1828–1914), English manufacturer who invented the carbon process for photographic printing in 1866 and pioneered gelatin dry plates for instantaneous photography, 1879-81.
Stonethrow Ridge is a snow-covered ridge rising west of Fumarole Bay on Deception Island, in the South Shetland Islands of Antarctica. Vapour Col lies to the south of the ridge.
Tuning Nunatak is a small rock nunatak 1 nautical mile (1.9 km) north of Darling Ridge, Ohio Range. Surveyed by the United States Antarctic Research Program (USARP) Horlick Mountains Traverse party in December 1958. Named by Advisory Committee on Antarctic Names (US-ACAN) for Preston O. Tuning, meteorologist at Byrd Station in 1960.
Elliott Passage is a marine channel running northeast–southwest between the southeast coast of Adelaide Island and Jenny Island. It was named by the UK Antarctic Place-Names Committee in 1984 after Captain Christopher R. Elliott, Master of the RRS John Biscoe from 1975, having also served in other officer positions on the John Biscoe and the RRS Bransfield from 1967.
Hooper Glacier is a glacier 3 nautical miles (6 km) long, flowing from the col north of Mount William into the west side of Börgen Bay, Anvers Island, in the Palmer Archipelago, Antarctica. It was surveyed by the Falkland Islands Dependencies Survey (FIDS) in 1955, and named by the UK Antarctic Place-Names Committee for Peter R. Hooper of FIDS, leader and geologist at the Arthur Harbour station in 1955 and 1956.
Tinsel Dome is a small ice-covered hill, 700 m, standing between Aureole Hills and Bone Bay on Trinity Peninsula. Charted in 1948 by the Falkland Islands Dependencies Survey (FIDS) who gave this descriptive name.
Russell East Glacier is a glacier, 6 nautical miles (11 km) long and 3 nautical miles (6 km) wide, which lies at the north end of Detroit Plateau and flows from Mount Canicula and Verdikal Gap along the south slopes of Erul Heights eastward into Smokinya Cove in Prince Gustav Channel on the south side of Trinity Peninsula. This glacier together with Russell West Glacier, which flows westward into Bone Bay on the north side of Trinity Peninsula, form a through glacier across the north part of Antarctic Peninsula. It was first surveyed in 1946 by the Falkland Islands Dependencies Survey (FIDS). Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for V.I. Russell, surveyor and leader of the FIDS base at Hope Bay in 1946.
Reeve Island is an island 1.5 nautical miles long, lying between Knight and Friar islands in the Wauwermans Islands, in the Wilhelm Archipelago. Shown on an Argentine government chart of 1950. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1958 after one of the characters in Chaucer's Canterbury Tales.
Lemaire Island is an island 4.5 nautical miles (8 km) long and 1.5 nautical miles (3 km) wide, lying 1 nautical mile (2 km) west of Duthiers Point off the west coast of Graham Land, Antarctica. It was discovered by the Belgian Antarctic Expedition, 1897–99, under Adrien de Gerlache, who named it for Charles Antoine Lemaire. The island is bordered by the Aguirre Passage which separates it from the Danco Coast.
Lenie Passage is a northwest–southeast passage 1 nautical mile (2 km) wide between the Gossler Islands and the Joubin Islands in the Palmer Archipelago, Antarctica. It was named by the Advisory Committee on Antarctic Names for Pieter J. Lenie, Master of the RV Hero in 1972–73 and 1973–74. Lenie is believed to be first to navigate and carry out sounding of this passage, in the Hero in January and February 1973.
