(Redirected from Tharp Ice Rise)

Violante Inlet (72°35′S 61°5′W / 72.583°S 61.083°W / -72.583; -61.083) is an ice-filled inlet 16 nautical miles (30 km; 18 mi) long, in an east–west direction, and 12 to 15 nautical miles (22 to 28 km; 14 to 17 mi) wide, lying between Cape Fanning and Cape Herdman along the east coast of Palmer Land, Antarctica.[1]

Location edit

 
Northern Palmer Land. Violante Inlet in southeast of map

The Violante Inlet is on the Black Coast of Palmer Land, beside the Weddell Sea to the east. It is south of the Merz Peninsula, east of the Du Toit Mountains and the Wegener Range and north of the Mason Inlet and Kemp Peninsula. The mouth of the Violante Inlet extends from Cape Fanning in the north to Cape Herdman in the south. Pullen Island lies in the head of Violante Inlet, to the north of Maury Glacier, which joins Heezen Glacier to the east of Mount Reynolds and enters the inlet.[2]

Discovery and name edit

Violante Inlet was discovered and photographed from the air in December 1940 by members of the United States Antarctic Service (USAS) and named for Major (later Colonel) André L. Violante, USA, who designed the prefabricated buildings used by the expedition. Particularly because of a false floor, they proved to be the must satisfactory quarters used by American Antarctic expeditions.[1]

Discovered and photographed from the air in December 1940 by members of the USAS. During 1947 the glacier was photographed from the air by members of the Ronne Antarctic Research Expedition (RARE) under Finn Ronne, who in conjunction with the Falkland Islands Dependencies Survey (FIDS) charted it from the ground. Named by the FIDS for Giinther Bohnecke, German oceanographer and member of the German expedition in the Meteor, 1925-27.[3]

Discovered 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 Professor Albert Defant, German oceanographer (Austrian born) who was director of the Inst. fur Meereskunde (German Hydrographic Office), 1927-46.[4]
