Cape De la Motte

Last updated

Cape De la Motte is a prominent cape in George V Land in Antarctica separating Watt Bay and Buchanan Bay. Just to the south, the continental ice surface rises 520 metres (1,700 ft) at Mount Hunt. The cape was charted by the Australasian Antarctic Expedition (1911–14) under Douglas Mawson, who named it for C. P. de la Motte, third officer on the expedition ship Aurora. It has been conjectured that the high land behind this cape is "Point Case", which the United States Exploring Expedition (1838–42) under Lieutenant Charles Wilkes saw from what was called "Disappointment Bay" on January 23, 1840.

George V Land is a segment of Antarctica part of the land claimed as part of the Australian Antarctic Territory, inland from the George V Coast. As with other segments of Antarctica, it is defined by two lines of longitude, 142°02' E and 153°45' E, and by the 60°S parallel. This region was first explored by members of the Main Base party of the Australasian Antarctic Expedition (1911-14) under Douglas Mawson, who named this feature for King George V of the United Kingdom.

Antarctica Polar continent in the Earths southern hemisphere

Antarctica is Earth's southernmost continent. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,000,000 square kilometres, it is the fifth-largest continent. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.

Watt Bay is a bay about 16 nautical miles (30 km) wide indenting the coast between Garnet Point and Cape De la Motte. Discovered by the Australasian Antarctic Expedition (1911–14) under Douglas Mawson, who named it for W.A. Watt, Premier of Victoria in 1911.

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.
