Harrison Passage ( 65°53′S65°11′W / 65.883°S 65.183°W / -65.883; -65.183 Coordinates: 65°53′S65°11′W / 65.883°S 65.183°W / -65.883; -65.183 ) is a passage between Larrouy Island and Tadpole Island to the west, and the Llanquihue Islands and the west coast of Graham Land, Antarctica, to the east. It was photographed by Hunting Aerosurveys Ltd in 1956–57, and was mapped from these photos by the Falkland Islands Dependencies Survey. It was named by the UK Antarctic Place-Names Committee in 1959 for John Harrison, an English horologist who first definitely solved the problem of determining longitude at sea. [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.

Larrouy Island

Larrouy Island is an island 9 kilometres (5 nmi) long and 4 kilometres (2 nmi) wide which rises to 745 metres (2,440 ft), lying in Grandidier Channel off the northwest coast of Velingrad Peninsula 7 kilometres (4 nmi) north of Ferin Head, Antarctica. It was discovered by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot, who named it for Paul Augustin Jean Larrouy, at that time a French Minister Plenipotentiary.

Tadpole Island is an island just north of Ferin Head, off the west coast of Graham Land. Charted by the British Graham Land Expedition (BGLE) under Rymill, 1934-37. The name, given by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1959, is descriptive of the island's shape when seen from the air.

Martin Glacier is a glacier, 3 nautical miles (6 km) wide and 9 nautical miles (17 km) long, which flows west and then northwest from the south side of Mount Lupa to the southeast corner of Rymill Bay where it joins Bertrand Ice Piedmont, on the west coast of Graham Land, Antarctica. It was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Riddoch Rymill, and was resurveyed in 1948–1949 by the Falkland Islands Dependencies Survey. The glacier was named for James H. Martin, a member of the British Australian and New Zealand Antarctic Research Expedition (1929–1931) under Sir Douglas Mawson, and first mate of the Penola during the BGLE.

Explorers Range

Explorers Range is a large mountain range in the Bowers Mountains of Victoria Land, Antarctica, extending from Mount Bruce in the north to Carryer Glacier and McLin Glacier in the south.
