Danco Island or Isla Dedo is an island off Antarctica, 2 kilometres (1 nmi) long lying in the southern part of Errera Channel, off the west coast of Graham Land. It was charted by the Belgian Antarctic Expedition under Adrien de Gerlache, 1897–1899. Danco Island was surveyed by the Falkland Islands Dependencies Survey from Norsel in 1955, and named by the UK Antarctic Place-names Committee for Emile Danco (1869–1898), a Belgian geophysicist and member of the Belgian Antarctic Expedition, who died on board Belgica in the Antarctic.
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.

Kirkby Shoal is a small shoal area with depths of less than 18 metres (59 ft) extending about 140 metres (459 ft) westwards and SSW, about 3.4 kilometres (2.1 mi) from the summit of Shirley Island, Windmill Islands, and 0.24 kilometres (0.15 mi) NW of Stonehocker Point, Clark Peninsula.
Snow Hill Island is an almost completely snowcapped island, 33 km (21 mi) long and 12 km (7.5 mi) wide, lying off the east coast of the Antarctic Peninsula. It is separated from James Ross Island to the north-east by Admiralty Sound and from Seymour Island to the north by Picnic Passage. It is one of several islands around the peninsula known as Graham Land, which is closer to South America than any other part of the Antarctic continent.
Gain Glacier is a large glacier on the east coast of Palmer Land, Antarctica, flowing northeast from Cat Ridge and entering the Weddell Sea between Imshaug Peninsula and Morency Island. It was mapped by the United States Geological Survey in 1974, and was named by the Advisory Committee on Antarctic Names for Louis Gain, a naturalist on the French Antarctic Expedition, 1908–10, and the author of several of the expedition reports on zoology and botany.
Endurance Glacier is a broad glacier north of Mount Elder, draining south-east to the south coast of Elephant Island in the South Shetland Islands of Antarctica, and is the main discharge glacier on the island. It was named by the UK Antarctic Place-Names Committee after HMS Endurance, which anchored off the glacier on several occasions in support of the Joint Services Expedition to Elephant Island, 1970–71.
Dibble Glacier in Antarctica is a prominent channel glacier flowing from the continental ice and terminating in a prominent tongue at the east side of Davis Bay. It was delineated from air photos taken by U.S. Navy Operation Highjump (1946–47), and named by the Advisory Committee on Antarctic Names for Jonas Dibble, ship's carpenter on the sloop Peacock of the United States Exploring Expedition (1838–42) under Charles Wilkes. Dibble is credited with leaving his sick bed and working 24 hours without relief with other carpenters to repair a broken rudder on the Peacock, when the ship was partially crushed in an ice bay in 151°19′E and forced to retire northward.
Posadowsky Glacier is a glacier about 9 nautical miles long, flowing north to Posadowsky Bay immediately east of Gaussberg. Posadowsky Bay is an open embayment, located just east of the West Ice Shelf and fronting on the Davis Sea in Kaiser Wilhelm II Land. Kaiser Wilhelm II Land is the part of East Antarctica lying between Cape Penck, at 87°43'E, and Cape Filchner, at 91°54'E, and is claimed by Australia as part of the Australian Antarctic Territory. Other notable geographic features in this area include Drygalski Island, located 45 mi NNE of Cape Filchner in the Davis Sea, and Mirny Station, a Russian scientific research station.
Bartók Glacier is a glacier, 7 nautical miles (13 km) long and 3 nautical miles (6 km) wide, flowing southwest from the southern end of the Elgar Uplands in the northern part of Alexander Island. It was first photographed from the air and roughly mapped by the British Graham Land Expedition in 1937, and more accurately mapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960. It was named by the UK Antarctic Place-Names Committee after the Hungarian composer Béla Bartók.
Deadmond Glacier is a glacier about 6 nautical miles (11 km) long, flowing from the east side of Evans Peninsula on Thurston Island into Cadwalader Inlet. It was discovered by the U.S. Navy Bellingshausen Sea Expedition in February 1960, and was named by the Advisory Committee on Antarctic Names for Lieutenant Commander Robert B. Deadmond, executive officer of USS Burton Island, forming part of this expedition.
Dufayel Island is an island lying near the center of Ezcurra Inlet, Admiralty Bay, in the South Shetland Islands. It was charted and named in December 1909 by the French Antarctic Expedition under Jean-Baptiste Charcot.
Gibbs Glacier is a glacier, 15 nautical miles (28 km) long, flowing southeast into the northern part of Mercator Ice Piedmont on the east side of the Antarctic Peninsula. This feature together with Neny Glacier, which flows northwest, occupy a transverse depression between Mercator Ice Piedmont and Neny Fjord on the west side of the Antarctic Peninsula. Gibbs Glacier was photographed from the air and first mapped by the United States Antarctic Service, 1939–41, and the Ronne Antarctic Research Expedition, 1947–48. It was named by the UK Antarctic Place-Names Committee for Peter M. Gibbs of the Falkland Islands Dependencies Survey, a surveyor at Horseshoe Island, 1957, and leader at Stonington Island, 1958, who was responsible for the first ground survey of the glacier.
Gnomon Island is a small rocky island lying just north of Point Wild, on Elephant Island in the South Shetland Islands. It was charted by Ernest Shackleton's Endurance expedition, 1914–16, and so named by them because when viewed from Point Wild the shape of the feature is suggestive of a gnomon, the elevated arm of a sundial.
González Island is a small island on the south side of the entrance to Iquique Cove, Discovery Bay, Greenwich Island in the South Shetland Islands. On its west side the island is linked by a split to a smaller island, which is covered at high tide. The island was charted by the Chilean Antarctic Expedition of 1947, and commanded by Capitan de Navio Federico Guesalaga Toro, who named it after Ernesto González Navarrete, captain of the ship Iquique on the expedition.
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.
Hawker Island is an irregularly shaped island about 2 km (1.2 mi) long, lying some 7 km south-west of Davis Station between Mule Island and Mule Peninsula, Vestfold Hills, in the eastern part of Prydz Bay, Antarctica. It was mapped by Norwegian cartographers from aerial photographs taken by the Lars Christensen Expedition, 1936–37. It was remapped by the Australian National Antarctic Research Expeditions (1957–58) and named after Alan Charles Hawker, a radio supervisor at Davis Station in 1957.
