Donald Nunatak ( 65°5′S60°6′W / 65.083°S 60.100°W / -65.083; -60.100 Coordinates: 65°5′S60°6′W / 65.083°S 60.100°W / -65.083; -60.100 ) is a nunatak 1.5 nautical miles (3 km) north of Gray Nunatak in the Seal Nunataks group, off the east coast of the Antarctic Peninsula. It was charted in 1902 by the Swedish Antarctic Expedition under Otto Nordenskiöld, and named by him for Dr. C.W. Donald, ship's doctor and naturalist on the Active, one of the vessels of the Dundee Whaling Expedition, 1892–93. [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.

Nunatak Exposed, often rocky element of a ridge, mountain, or peak not covered with ice or snow within an ice field or glacier

A nunatak is an exposed, often rocky element of a ridge, mountain, or peak not covered with ice or snow within an ice field or glacier. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons.

Gray Nunatak is a nunatak which lies 1.5 nautical miles (3 km) west of Arctowski Nunatak in the Seal Nunataks group, off the east coast of the Antarctic Peninsula. It was first charted by the Swedish Antarctic Expedition under Otto Nordenskiöld during a sledge journey in 1902, and named by him probably for Captain David Gray, a whaling skipper of Peterhead, Scotland. Gray had planned an expedition to the Weddell Sea in 1891 but the plan was abandoned due to a lack of funds.

It was first seen and mapped as an island in December 1893 by a Norwegian Sealing expedition under C.A. Larsen, who named it after the Castor, a ship which combined sealing and exploring activities along the west coast of the Antarctic Peninsula under Captain Morten Pedersen in 1893–94. The feature was determined to be a nunatak in 1902 by the Swedish Antarctic Expedition under Otto Nordenskiöld.
