Canopus Islands is a group of small islands just north of the Klung Islands in the eastern part of Holme Bay, Mac. Robertson Land. They were mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37, and named by the Australian National Antarctic Research Expeditions after the star Canopus.
The Knight Rocks are a group of small rocks which lie 8 kilometres (4.5 nmi) west-northwest of the south end of Snow Island, in the South Shetland Islands. The rocks were so named by the UK Antarctic Place-Names Committee following a survey by Lieutenant Commander F.W. Hunt, Royal Navy, in 1951–52, because of their proximity to Castle Rock.
Paterson Islands is a group of small islands lying 7.4 kilometres (4 nmi) northeast of Klung Islands, 3.7 kilometres (2 nmi) southeast of Wiltshire Rocks and Kitney Island, and 5.6 kilometres (3 nmi) southeast of Smith Rocks, close along the coast of Mac. Robertson Land. Mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936-37. Named by Antarctic Names Committee of Australia (ANCA) for A.J.F. Paterson, supervisory technician (radio) at Mawson Station, 1963.
Goff Glacier is a broad glacier flowing from Parker Peak into the head of Koether Inlet on the north side of Thurston Island, Antarctica. It was named by the Advisory Committee on Antarctic Names after Lieutenant Robert G. Goff, co-pilot of PBM Mariner aircraft in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas, 1946–47.
Gourdin Island is the largest island (124 ha) in a group of islands and rocks 2 km (1 nmi) north of Prime Head, the northern tip of the Antarctic Peninsula. It was discovered by a French expedition, 1837–40, under Captain Jules Dumont d'Urville, and named by him for Ensign Jean Gourdin of the expedition ship Astrolabe. The island was reidentified and charted by the Falkland Islands Dependencies Survey in 1945–47.
The Moss Islands are a group of small islands and rocks lying east of Midas Island and north of Apéndice Island in Hughes Bay, off the west coast of Graham Land, Antarctica. They were first charted in detail and given the descriptive name "Moos Inseln" by the Swedish Antarctic Expedition under Otto Nordenskiöld in 1902.
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.
Mincer Glacier is a broad glacier flowing from Zuhn Bluff into the southeast arm of Murphy Inlet on the north side of Thurston Island, Antarctica. It was named by the Advisory Committee on Antarctic Names after Lieutenant Dale F. Mincer, a co-pilot of PBM Mariner aircraft in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas in 1946–47.
Litz Glacier is a glacier flowing northeast from the vicinity of Smith Peak and Litz Bluff in north-central Thurston Island, Antarctica. The glacier enters the west part of Peale Inlet north of the Guy Peaks. It was named by the Advisory Committee on Antarctic Names after A.K. Litz, Chief Photographer's Mate in the Eastern Group of Operation Highjump, which obtained aerial photographs of this glacier and adjacent coastal areas, 1946–47.
Liotard Glacier is a channel glacier in Antarctica. It is about 3 nautical miles (6 km) wide and 6 nautical miles (11 km) long, and flows north-northeast from the continental ice, terminating in a small ice tongue about 4 nautical miles (7 km) west of Hélène Island. The glacier was delineated from air photos taken by U.S. Navy Operation Highjump, 1946–47, and was named by the Advisory Committee on Antarctic Names for Andre-Frank Liotard, the leader of the French Antarctic Expedition, 1949–51, whose group completed the initial survey of the coastal features as far westward as this glacier.
Klung Island is the largest island of the Klung Islands lying in Holme Bay, Mac. Robertson Land, Antarctica. It was mapped by Norwegian cartographers from aerial photos taken by the Lars Christensen Expedition, 1936–37, as part of "Klungholmane", and was named by the Antarctic Names Committee of Australia after the Klung Islands.
Mahaffey Glacier is a glacier flowing into the head of Morgan Inlet at the east end of Thurston Island, Antarctica. It was named by the Advisory Committee on Antarctic Names after J.S. Mahaffey, a Photographer's Mate in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas in 1946–47.
Marck Glacier is a glacier flowing into the southwestern extremity of Cadwalader Inlet on the north side of Thurston Island, Antarctica. It was named by the Advisory Committee on Antarctic Names after Aviation Machinist's Mate George H. Marck, an aircrewman in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas in the summer of 1946–47.
Levko Glacier is a glacier flowing from Pallid Crest to the eastern end of Thurston Island, Antarctica. It enters Seraph Bay between Tierney Peninsula and Simpson Bluff. The glacier was named by the Advisory Committee on Antarctic Names after G. Levko, Photographer's Mate in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas, 1946–47.
