The Ambrose Rocks ( 65°16′S64°22′W / 65.267°S 64.367°W / -65.267; -64.367 Coordinates: 65°16′S64°22′W / 65.267°S 64.367°W / -65.267; -64.367 ) are a small cluster of rocks situated southwest of the southern Argentine Islands and 1 nautical mile (2 km) northwest of the Gaunt Rocks, off the west coast of Graham Land, Antarctica. They were named by the UK Antarctic Place-Names Committee for David A. Ambrose, a survey assistant of the Hydrographic Survey Unit from HMS Endurance working in this area in February 1969. [1]

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Argentine Islands group of islands in the Wilhelm Archipelago of Antarctica, 9 km SW of Petermann Island, 7 km NW of Cape Tuxen, Kiev Peninsula, Graham Land; discovered by the French Antarctic Expedition 1903–05; so named to thank Argentinas support to the expedition

The Argentine Islands are a group of islands in the Wilhelm Archipelago of Antarctica, situated 5 nautical miles (9 km) southwest of Petermann Island, and 4 nautical miles (7 km) northwest of Cape Tuxen on Kiev Peninsula in Graham Land. They were discovered by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot, and named by him for the Argentine Republic in appreciation of that government's support of to his expedition.

The Gaunt Rocks are a small group of rocks lying 2 nautical miles (4 km) west of the Barros Rocks, in the Wilhelm Archipelago. They were roughly charted by the British Graham Land Expedition under John Rymill, 1934–37, and more accurately positioned by the Falkland Islands Dependencies Survey from photos taken by Hunting Aerosurveys Ltd in 1956–57. The name, given by the UK Antarctic Place-Names Committee in 1959, is descriptive of these desolate, grim-looking rocks.
