The Balleny Islands are a series of uninhabited islands in the Southern Ocean extending from 66°15' to 67°35'S and 162°30' to 165°00'E. The group extends for about 160 km (99 mi) in a northwest-southeast direction. The islands are heavily glaciated and of volcanic origin. Glaciers project from their slopes into the sea. The islands were formed by the so-called Balleny hotspot.
Thurston Island is a largely ice-covered, glacially dissected island, 135 nautical miles long and 55 nautical miles wide, lying between Amundsen Sea and Bellingshausen Sea a short way off the northwest end of Ellsworth Land, Antarctica. The island is separated from the mainland by Peacock Sound, which is occupied by the west portion of Abbot Ice Shelf.
Rymill Bay is a bay, 9 nautical miles wide at its mouth and indenting 5 nautical miles between Red Rock Ridge and Bertrand Ice Piedmont along the west coast of Graham Land, Antarctica.
Amundsen Bay, also known as Ice Bay, is a long embayment 39 kilometres (24 mi) wide, close west of the Tula Mountains in Enderby Land, Antarctica. The bay was seen as a large pack-filled recession in the coastline by Sir Douglas Mawson on 14 January 1930. Seen by Captain Hjalmar Riiser-Larsen in charge of a Norwegian expedition during an airplane flight on 15 January and subsequently mapped nearer its true position by the Norwegians. The bay was mapped in detail by an Australian National Antarctic Research Expeditions party landed by aircraft in 1956 and another landed by launch from Thala Dan in February 1958. It was named by Mawson after Roald Amundsen, the Norwegian explorer who was first to reach the South Pole.
Enderby Land is a projecting landmass of Antarctica. Its shore extends from Shinnan Glacier at about 67°55′S44°38′E to William Scoresby Bay at 67°24′S59°34′E, approximately 1⁄24 of the earth's longitude. It was first documented in western and eastern literature in February 1831 by John Biscoe aboard the whaling brig Tula, and named after the Enderby Brothers of London, the ship's owners who encouraged their captains to combine exploration with sealing.
The Duroch Islands are a group of islands and rocks which extend over an area of about 3 nautical miles, centred about 1 nautical mile off Cape Legoupil on the north coast of Trinity Peninsula, Antarctica. The islands are close to Chile's Base General Bernardo O'Higgins Riquelme at Cape Legoupil.
Cape Jules is a rocky cape with a small cove along its northern end, 3 nautical miles (6 km) west of Zelee Glacier Tongue, Antarctica. It was discovered and named by the French expedition under Dumont d'Urville, 1837–40. Jules is the given name of the discoverer, Captain Jules Dumont d'Urville, as well as his son. The area was charted by the Australasian Antarctic Expedition in 1912–13, and again by the British Australian and New Zealand Antarctic Research Expedition in 1931, both under Mawson. The French Antarctic Expedition under Michel Barre established astronomical control at this locality in 1951.
Mount Denham is a mountain 1 nautical mile (2 km) northwest of Mount Keyser, in the eastern part of the Tula Mountains in Enderby Land. It was plotted from air photos taken from Australian National Antarctic Research Expeditions aircraft in 1957, and was named by the Antarctic Names Committee of Australia for W.M. Denham, a weather observer at Mawson Station in 1961.
Styles Bluff is a light-colored rock bluff at the southeast side of Edward VIII Plateau, rising out of the sea 1 nautical mile (1.9 km) north of Cape Gotley. Mapped by Norwegian cartographers from aerial photos taken by the Lars Christensen Expedition, 1936–37. First visited in February 1960 by an ANARE party led by D.F. Styles, Asst. Director, Antarctic Division, Melbourne, for whom this feature was named.
The Playfair Mountains are a group of mountains between Swann Glacier and Squires Glacier in southeast Palmer Land, Antarctica.
Matusevich Glacier is a broad glacier about 50 nautical miles long, with a well developed glacier tongue, flowing to the coast of East Antarctica between the Lazarev Mountains and the northwestern extremity of the Wilson Hills.
Megaw Island is the easternmost of the Bennett Islands in Hanusse Bay, Antarctica. It was mapped from air photos taken by the Ronne Antarctic Research Expedition (1947–48) and the Falkland Islands and Dependencies Aerial Survey Expedition (1956–57). The island was named by the UK Antarctic Place-Names Committee for Irish physicist Helen Megaw, who in 1934 made accurate measurements of the cell dimensions of ice.
McCance Glacier is the 30-km long and 5 km wide glacier draining the Hutchison Hill area on the west slopes of Avery Plateau on Loubet Coast in Graham Land, Antarctica. It flows north-northwestwards along the west side of Osikovo Ridge, Kladnitsa Peak and Rubner Peak and enters Darbel Bay.
Steinemann Island is an island off the northeast coast of Adelaide Island, about 10 nautical miles (18 km) southwest of Mount Velain. Mapped from air photos taken by Ronne Antarctic Research Expedition (RARE) (1947–48) and Falkland Islands and Dependencies Aerial Survey Expedition (FIDASE) (1956–57). Named by United Kingdom Antarctic Place-Names Committee (UK-APC) for Samuel Steinemann, Swiss physicist who has made laboratory investigations on the flow of single and polycrystalline ice.
Sirius Islands is a chain of islands in the north part of the Oygarden Group in Antarctica. Mapped by Norwegian cartographers from aerial photos taken by the Lars Christensen Expedition, 1936–37, and called Nordoyane. The group was first visited by an ANARE party in 1954; this chain was renamed by Antarctic Names Committee of Australia (ANCA) after the star Sirius which was used for an astrofix in the vicinity.
Mount Letten is a mountain 1 nautical mile (2 km) south of Mount Storer, in the Tula Mountains of Enderby Land, Antarctica. It was plotted from air photos taken from Australian National Antarctic Research Expeditions aircraft in 1956 and 1957 and was named by the Antarctic Names Committee of Australia for W.H. Letten, a member of the crew of the RSS Discovery during the British Australian New Zealand Antarctic Research Expedition of 1929–31.
The James Ross Island group is a group of islands located close to the northeastern tip of the Antarctic Peninsula. The largest islands in the group are James Ross Island, Snow Hill Island, Vega Island, and Seymour Island. The islands lie to the south of the Joinville Island group. The groups contains several scientific bases, notably Marambio Base, and numerous important palaeontological sites.
