GEOGRAPHIC NAMES OF ANTARCTICA 



DEBUTANTE ISLAND: rocky island, about 1 mi. 

 long and 0.2 mi. wide, marking the largest and 

 southernmost of the S0strene Is., lying about 5 mi. 

 W. of Ingrid Christensen Coast; in about 69°36'S., 

 74°59'E. Charted by Norwegian cartographers, 

 from aerial photographs taken in January 1937 by 

 the Nor. exp. under Lars Christensen, as a small 

 rock outcrop protruding above what was thought 

 to form part of an ice shelf. So named by John 

 H. Roscoe, following his 1952 compilation from USN 

 Op. Hjp. aerial photographs taken in March 1947, 

 because of the recent appearance of this feature 

 above the consolidated sea ice between Polar Record 

 and Polararboken Glacier Tongues. Not adopted: 

 Debutante. 



DECAZES, POINT: southernmost point on the 

 island marking the SW. end of the Biscoe Is., at the 

 N. side of Matha Str.; in about 66°30'S., 67°29'W. 

 Charted and named by the FrAE, 1908-10, under 

 Charcot. Not adopted: Decazes Point. 



DECEPTION ISLAND : ring-shaped island about 

 8 or 9 mi. in diameter, with a narrow entrance into 

 a central landlocked harbor (a drowned breached 

 crater), lying about 6 mi. S. of Livingston I., in 

 the South Shetland Is.; in about 62°57'S., 60°38'W. 

 The name dates back to at least 1821 and is now 

 established international usage. Not adopted: 

 Teil Island. 



Decousovte, Cap; Decouverte, Cap de la: see De- 

 couverte. Cape. 



DECOUVERTE, CAPE: low rocky cape marking 

 the NW. end of the large islet at the NW. end of 

 the Curzon Its., close off Adelie Coast; in 66°46'S., 

 141°33'E. Disc, by a Fr. exp. under D'Urville, who 

 landed on the islet on Jan. 21, 1840, and so named 

 because it marked the first rock outcrop observed 

 along this coast. The name was applied on 

 D'Urville's 1840 chart to the small cape on the ice- 

 drowned coast immediately behind the Curzon 

 Islets. Roughly charted by the AAE under Maw- 

 son, 1911-14, who reassigned the name to the sea- 

 ward end of the large islet upon which D'Urville's 

 group landed. This interpretation was confirmed 

 by the FrAE under Barre, who surveyed this coastal 

 area in 1951-52. Not adopted: Cap Decousovte, 

 Cape Decouverte, Cap de la Decouverte [French], 

 Cape Discovery. 



DE DION ISLETS: group of islets surrounded 

 by reefs, lying in the N. part of Marguerite Bay, 

 about 8 mi. SW. of Cape Alexandra, Adelaide I.; in 

 67°52'S., 68°43'W. Disc, by the FrAE, 1908-10, 

 under Charcot, and named by him for the Marquis 

 de Dion, who donated three motor sledges and 



whose De Dion-Bouton works produced equipment 

 for the expedition. Not adopted: De Dion Islands, 

 Dion Islets. 



DEE ISLAND: crescent-shaped island, with a 

 conspicuous, sharp peak about 850 ft. in el. at its 

 S. end, about 2.5 mi. WNW. of Fort William, close 

 off the N. side of Greenwich I., in the South Shet- 

 land Is.; in 62°25'S., 59°50'W. Charted and named 

 in 1935 by DI personnel on the Discovery II. 



DEFANT GLACIER: glacier about 2 mi. wide at 

 its mouth, which flows ESE. to the W. side of 

 Violante Inlet, on the E. coast of Palmer Pen.; in 

 72°32'S., 61°35'W. Disc, and photographed from 

 the air in December 1940 by the USAS. During 

 1947 the glacier was photographed from the air by 

 members of the RARE, who in conjunction with the 

 FIDS charted it from the ground. Named by the 

 FIDS for Prof. Albert Defant, German oceanog- 

 rapher (Austrian born) who was Dir. of the Inst, 

 fiir Meereskunde (German Hydrographic Office), 

 1927-46. 



DE GERLACHE, CAPE: cape which forms the 

 NE. tip of Davis Pen., on Queen Mary Coast; in

 Disc, by the FrAE, 1903-5, under Charcot, and 

 named by him for Lt. Adrien de Gerlache. Not 

 adopted: Gerlache Point, Pointe de Gerlache 

 [French] . 



DE GERLACHE STRAIT: strait separating the 

 Palmer Arch, from Palmer Pen.; in about 64°30'S., 

 62°20'W. The BelgAE, under Lt. Adrien de Ger- 

 lache, explored the strait in January and Febru-
