Gunnel Channel ( 67°6′S67°33′W / 67.100°S 67.550°W / -67.100; -67.550 Coordinates: 67°6′S67°33′W / 67.100°S 67.550°W / -67.100; -67.550 ) is a channel, 0.5 nautical miles (1 km) wide and 7 nautical miles (13 km) long, situated in the south part of Hanusse Bay and separating Hansen Island from the west coast of Graham Land, Antarctica. It was first observed from the air and roughly charted in 1936 by the British Graham Land Expedition under John Rymill. It was surveyed from the ground in 1948 by the Falkland Islands Dependencies Survey who gave this descriptive name. The channel gives a false impression of such narrowness that a boat could not navigate it without scraping her "gunnels" (gunwales) on either side. [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.

Hanusse Bay is a broad bay, 37 kilometres (20 nmi) long in a general north-south direction, lying between the northern portions of Adelaide Island and Arrowsmith Peninsula, Antarctica. The bay was discovered and first charted by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, and named by him for the director of the Hydrographic Service of the French Navy Ferdinand Isidore Hanusse (1848–1921).

Hansen Island is an island 6 nautical miles (11 km) long and 3 nautical miles (6 km) wide, lying immediately north of The Gullet at the head of Hanusse Bay, off the west coast of Graham Land, Antarctica. It was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Rymill, who used the provisional name "North Island" for this feature. The island was resurveyed in 1948 by the Falkland Islands Dependencies Survey, and was renamed in 1954 by the UK Antarctic Place-Names Committee for Leganger H. Hansen, manager at Messrs. Christian Salvesen's whaling station at Leith Harbor, South Georgia, 1916–37, who gave great assistance to the BGLE, 1934–37.

Cape Longing Refuge in Argentina

Cape Longing is a rocky cape on the east coast of Graham Land, Antarctica, forming the south end of a large ice-covered promontory which marks the west side of the south entrance to Prince Gustav Channel. It was discovered by the Swedish Antarctic Expedition under Otto Nordenskiöld in 1902, and so named by him because from the position of his winter hut on Snow Hill Island the cape lay in the direction of his "land of longing" which he was anxious to explore.
