Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west. Alexander Island is about 390 kilometres (240 mi) long in a north-south direction, 80 kilometres (50 mi) wide in the north, and 240 kilometres (150 mi) wide in the south. Alexander Island is the second largest uninhabited island in the world, after Devon Island.
Berkner Island is an Antarctic ice rise, where bedrock below sea level has caused the surrounding ice sheet to create a dome. If the ice cap were removed, the island would be under water. Berkner "Island" is high and completely ice-covered and about 320 kilometres (200 mi) long and 150 kilometres (93 mi) wide, with an area of 44,000 km2 (17,000 sq mi). It is surrounded by the Filchner-Ronne Ice Shelf. The northernmost point of the Berkner is about 20 kilometres (12 mi) from the open sea. It lies in the overlapping portion of the Argentine and the British Antarctic territorial claims.
Palmer Land is the portion of the Antarctic Peninsula, Antarctica that lies south of a line joining Cape Jeremy and Cape Agassiz. This application of Palmer Land is consistent with the 1964 agreement between US-ACAN and UK-APC, in which the name Antarctic Peninsula was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69 degrees south.
Denman Glacier is a glacier 7 to 10 nautical miles wide, descending north some 70 nautical miles, which debouches into the Shackleton Ice Shelf east of David Island, Queen Mary Land. It was discovered in November 1912 by the Western Base party of the Australasian Antarctic Expedition under Sir Douglas Mawson. Mawson named the glacier for Lord Denman, Governor-General of Australia in 1911, a patron of the expedition.
Mertz Glacier is a heavily crevassed glacier in George V Coast of East Antarctica. It is the source of a glacial prominence that historically has extended northward into the Southern Ocean, the Mertz Glacial Tongue. It is named in honor of the Swiss explorer Xavier Mertz.
Veststraumen Glacier is a glacier about 45 miles long draining west along the south end of Kraul Mountains into Riiser-Larsen Ice Shelf. The glacier was seen in the course of a U.S. Navy LC-130 plane flight over the coast on November 5, 1967, and was plotted by the United States Geological Survey (USGS) from photographs obtained at that time. In 1969, the Advisory Committee on Antarctic Names (US-ACAN) gave the name "Endurance Glacier" to this feature, but that naming was rescinded because UK Antarctic Place-Names Committee (UK-APC) gave the identical name to a small glacier on Elephant Island. The descriptive name "Veststraumen" appears on a 1972 Norsk Polarinstitutt map.
Fowler Ice Rise is a very large Antarctic ice rise between Evans Ice Stream and Carlson Inlet, in the southwest part of the Ronne Ice Shelf. The feature appears to be completely ice-covered except for the Haag Nunataks, which protrude above the surface in the northwestern portion. It was mapped by the United States Geological Survey from Landsat imagery taken 1973–74, and named by the Advisory Committee on Antarctic Names for Captain Alfred N. Fowler, U.S. Navy, Commander of the U.S. Naval Support Force, Antarctica, 1972–74.
Ketchum Glacier is an eastward flowing glacier at the base of Palmer Land, Antarctica, about 50 nautical miles (90 km) long, descending between the Latady Mountains and the Scaife Mountains into Gardner Inlet. It was discovered by the Ronne Antarctic Research Expedition (RARE), 1947–48, under Finn Ronne, who named it for Commander Gerald Ketchum, U.S. Navy, commander of the icebreaker USS Burton Island (AG-88) which broke the ice to free the RARE from Marguerite Bay for the return home.
Prestrud Inlet is a re-entrant in the south side of the Edward VII Peninsula, at the northeast corner of the Ross Ice Shelf. It was named by the U.S. Antarctic Service expedition (1939–41) in honor of Lt. Kristian Prestrud, leader of Amundsen's Eastern Sledge Party in 1911, who was first to traverse this region.
Carroll Inlet is an inlet, 74 kilometres (40 nmi) long and 11 kilometres (6 nmi) wide, trending southeast along the coast of Antarctica between the Rydberg Peninsula and Smyley Island. The head of the inlet is divided into two arms by the presence of Case Island and is bounded to the east by Stange Ice Shelf. It was discovered on an airplane flight, December 22, 1940, by members of the United States Antarctic Service (USAS) (1939–1941), and named after Arthur J. Carroll, chief aerial photographer on USAS flights from the East Base.
Constellation Inlet is an ice-filled inlet, 30 nautical miles (60 km) long and 10 nautical miles (20 km) wide, between the Dott Ice Rise and the Skytrain Ice Rise at the southwest margin of the Ronne Ice Shelf. It was mapped by the United States Geological Survey from surveys and from U.S. Navy air photos, 1961–66, and named by the Advisory Committee on Antarctic Names for the Lockheed Super Constellation aircraft, C-121J. Equipped only with wheeled tricycle landing gear, it was for many years the principal carrier of personnel from the U.S. to New Zealand and thence to the ice runway near McMurdo Station. In addition to its role of hauling men and supplies, the "Connie" flew many hours of aerial photography over Antarctica.
Nantucket Inlet is an ice-filled inlet 6 nautical miles (11 km) wide, which recedes 13 nautical miles (24 km) in a northwest direction between the Smith Peninsula and Bowman Peninsula, along the east coast of Palmer Land, Antarctica. Discovered by members of the United States Antarctic Service (USAS) in a flight from East Base on December 30, 1940, and named for Nantucket Island, MA, home of early New England whalers of the first half of the 19th century.
Whirlwind Inlet is an ice-filled inlet that recedes inland for 7 nautical miles (13 km) and is 12 nautical miles (22 km) wide at its entrance between Cape Northrop and Tent Nunatak, along the east coast of Graham Land. Sir Hubert Wilkins discovered the inlet on his flight of December 20, 1928. Wilkins reported four large glaciers flowing into the inlet, which he named Whirlwind Glaciers because their relative position was suggestive of the radial cylinders of his Wright Whirlwind engine. The inlet was photographed from the air by the United States Antarctic Service (USAS) in 1940 and charted by the Falkland Islands Dependencies Survey (FIDS) in 1947.
Durrance Inlet is an ice-filled inlet 10 nautical miles (19 km) north of Veststraumen Glacier along the Princess Martha Coast of Antarctica. The inlet is 5 nautical miles (9 km) wide, recedes 12 nautical miles (22 km), and opens to the Riiser-Larsen Ice Shelf. It was plotted by the United States Geological Survey from aerial photographs obtained by U.S. Navy Squadron VXE-6 in a November 5, 1967 reconnaissance flight over this coast, and was named by the Advisory Committee on Antarctic Names for Lieutenant Frank M. Durrance, Jr. of the U.S. Navy Reserve, a navigator on that flight.
Long Glacier is a glacier about 8 nautical miles long in the southeastern part of Thurston Island, Antarctica. It flows south to the Abbot Ice Shelf, 14 nautical miles (26 km) west of Harrison Nunatak. The glacier was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–66, and was named by the Advisory Committee on Antarctic Names (US-ACAN) for Fred A. Long, Jr., an aviation machinist of U.S. Navy Squadron VX-6, who wintered at Little America V in 1957 and was in Antarctica in the 1960–61 and 1962–63 seasons.
Hercules Inlet is a large, narrow, ice-filled inlet which forms a part of the southwestern margin of the Ronne Ice Shelf. It is bounded on the west by the southeastern flank of the Heritage Range, and on the north by Skytrain Ice Rise. The inlet was named by the Advisory Committee on Antarctic Names for the LC-130 Hercules aircraft used by the U.S. Naval Support Force, Antarctica, as a photographic and load carrying plane.
Talutis Inlet is an ice-filled inlet in the western side of Fowler Ice Rise. The inlet opens onto Carlson Inlet just south of Kealey Ice Rise. Mapped by United States Geological Survey (USGS) from imagery provided by NASA Earth Resources Technology Satellite (ERTS-1), 1973-74. Named by Advisory Committee on Antarctic Names (US-ACAN) for Lieutenant William R. Talutis, U.S. Navy, Officer-in-Charge of the South Pole Station, 1972.
Matthes Glacier is a glacier 9 nautical miles (17 km) long, flowing east into Whirlwind Inlet between Demorest Glacier and Chamberlin Glacier, on the east coast of Graham Land, Antarctica. It was discovered by Sir Hubert Wilkins on a flight of December 20, 1928, and photographed from the air by the United States Antarctic Service in 1940. It was charted by the Falkland Islands Dependencies Survey in 1947 and named for François E. Matthes, then chief geologist with the U.S. Geological Survey.
Kealey Ice Rise is an ice rise, 40 nautical miles (70 km) long and 15 nautical miles (30 km) wide, forming a western lobe of the larger Fowler Ice Rise. It is situated just north of the junction of Talutis Inlet and Carlson Inlet, at the southwest side of the Ronne Ice Shelf. It was mapped by the United States Geological Survey from imagery provided by the NASA Earth Resources Technology Satellite (ERTS-1), 1973–74, and was named by the Advisory Committee on Antarctic Names for Lieutenant Gerald P. Kealey, U.S. Navy, medical officer at South Pole Station in 1971.
