Dean Rocks
Dean Rocks (-67.8°N, -68.93333°W) is a group of four rocks lying between Preston and Biggs Islands in Henkes Islands, off the south end of Adelaide Island. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for Engineer Mechanic Thomas Dean of the Royal Navy Hydrographic Survey Unit which first charted this feature in 1963.

Mount Dean
Mount Dean (-85.53333°N, -163°W) is a mountain, 1,620 m, standing at the northeast end of the Quarles Range, 2 nautical miles (3.7 km) northeast of Mount Belecz. Probably first seen by Roald Amundsen's polar party in 1911. First mapped by the Byrd Antarctic Expedition, 1928-30. Named by Advisory Committee on Antarctic Names (US-ACAN) for Jesse D. Dean, meteorologist with the South Pole Station party of 1962.

Mount Dearborn
Mount Dearborn (-77.23333°N, 160.13333°W) is a mountain, 2,300 m, between Mount Littlepage and the north part of the Willett Range, in Victoria Land. Named by the Advisory Committee on Antarctic Names (US-ACAN) in 1964, for John Dearborn, biologist at McMurdo Station, 1959 and 1961.

Mount Deardorff
Mount Deardorff (-85.8°N, -162.56667°W) is a prominent peak, 2,380 m, surmounting the massive ridge dividing the heads of Moffett and Steagall Glaciers in the Queen Maud Mountains. First mapped from ground surveys and air photos by the Byrd Antarctic Expedition, 1928-30. Named by Advisory Committee on Antarctic Names (US-ACAN) for J. Evan Deardorff who made cosmic ray studies at McMurdo Station in 1964.

Debarquement Rock
Debarquement Rock (-66.6°N, 140.06667°W) is an ice-free rock 0.1 nautical miles (0.2 km) long marking the north end of the Dumoulin Islands and the northeast end of Geologie Archipelago. The French expedition under Captain Jules Dumont d'Urville landed on a rocky islet in this vicinity in January 1840 and gave the name "Rocher du Debarquement." Positive identification of this feature has not been made, but on the basis of air photos taken by U.S. Navy Operation Highjump, 1946-47, and surveys and geological studies made by the French Antarctic Expedition during the 1950-52 period, the seaward position of Debarquement Rock is believed to correlate with the feature so named by d'Urville.

Debenham Glacier
Debenham Glacier (-77.16667°N, 162.63333°W) is a glacier flowing into the northern part of Wilson Piedmont Glacier on the coast of Victoria Land. First mapped by the Discovery expedition (1901-04). It was named by the British Antarctic Expedition (1910-13) for Frank Debenham, geologist with the expedition and Director of the Scott Polar Research Institute, 1925-48.

Debenham Islands
Debenham Islands (-68.13333°N, -67.11667°W) is a group of islands and rocks lying between Millerand Island and the west coast of Graham Land. Discovered and named by the British Graham Land Expedition (BGLE), 1934-37, under Rymill; the BGLE base was on Barry Island, in the center of the group, during part of this time. Named for Frank Debenham, who served as member of the BGLE Advisory Committee. == See also == * List of antarctic and sub-antarctic islands

Debenham Peak
Debenham Peak (-67.35°N, 50.43333°W) is a peak, 1,140 m, lying south of Amundsen Bay in the Scott Mountains, about 7 nautical miles (13 km) east of Mount Cronus. Discovered in January 1930 by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Mawson, who named it for Frank Debenham. The peak was more accurately positioned by ANARE (Australian National Antarctic Research Expeditions), 1954-58.

Debussy Heights
Debussy Heights (-69.88333°N, -71.38333°W) is a heights which rise to 1,300 m (at Ravel Peak) east of Mozart Ice Piedmont in the north part of Alexander Island. First mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947-48, by Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) after Claude Debussy (1862-1918), French composer.

Debutante Island
Debutante Island (-69.56667°N, 75.5°W) is a narrow island which is the southernmost of the Sostrene Islands. The island is ice covered except for a small rock outcrop and barely protrudes above the general level of the Publications Ice Shelf. Mapped by Norwegian cartographers from aerial photographs taken by the Lars Christensen Expedition, 1936-37. Named Debutante in 1952 by John H. Roscoe because the island is just beginning to "come out" from under its ice cover. == See also == * List of antarctic and sub-antarctic islands

Decazes Island
Decazes Island (-66.43333°N, -67.33333°W) is an island 0.5 nautical miles (0.9 km) long, lying 1.5 nautical miles (2.8 km) southwest of Belding Island at the southwest extremity of the Biscoe Islands. The island is one of the largest of many small islets and rocks that fringe the northern side of Matha Strait. The vicinity was charted by the French Antarctic Expedition (1908-10) under Jean B. Charcot, who applied the name "Pointe Decazes" to the south end of an island in this approximate position. The original application has been altered in recent years, and the name Decazes is now established in usage for the entire island described. == See also == * List of antarctic and sub-antarctic islands

Decennial Peak
Decennial Peak (-84.36667°N, 166.03333°W) is a peak (4,020 m) situated 3 nautical miles (6 km) southwest of Mount Kirkpatrick in Queen Alexandra Range. Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1958-65. Named by Advisory Committee on Antarctic Names (US-ACAN) in recognition of the Decennial of the Institute of Polar Studies, Ohio State University, in 1970, the same year the University celebrated its Centennial. The University and the Institute have been very active in Antarctic investigations since 1960.

Deception Glacier
Deception Glacier (-78.55°N, 158.55°W) is a glacier between the Warren and Boomerang Ranges, flowing south into upper Mulock Glacier. So named by the New Zealand party of the Commonwealth Trans-Antarctic Expedition (1956-58) because it appears to lead directly into Skelton Neve but instead drains southward.

Deception Island
Deception Island (-62.95°N, -60.63333°W) is a ring-shaped island 8 nautical miles (15 km) in diameter, with a narrow entrance into a central landlocked harbor (a drowned breached crater), lying nearly 10 nautical miles (18 km) south of Livingston Island, in the South Shetland Islands. The name dates back to at least 1821 and is now established in international usage. == See also == * List of antarctic and sub-antarctic islands
