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.

Branson Nunatak is a nunatak between Mount Burnett and Price Nunatak in the Framnes Mountains, Mac. Robertson Land. It was mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37, and named Horntind. It was renamed by the Antarctic Names Committee of Australia for J. Branson, geophysicist at Mawson Station in 1962.

United States Geological Survey Scientific agency of the United States government

The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.

Geographic Names Information System geographical database

The Geographic Names Information System (GNIS) is a database that contains name and locative information about more than two million physical and cultural features located throughout the United States of America and its territories. It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names.

Anare Mountains mountain range

The Anare Mountains are a large group of mainly snow-covered peaks and ridges along the northern coast of Victoria Land, Antarctica. The group is bounded on the north and east by the Pacific Ocean, on the west by Lillie Glacier, and on the south by Robertson Glacier, Ebbe Glacier and Dennistoun Glacier. Kirkby Glacier, 20 miles (32 km) in length, drains the central Anare Mountains and flows northwest to the sea 3 miles (5 km) from Cape North, and just north of Arthurson Bluff, northern Victoria Land. The mountain range is situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.

Lillie Glacier glacier

Lillie Glacier is a large glacier in Antarctica, about 100 nautical miles (190 km) long and 10 nautical miles (19 km) wide. It lies between the Bowers Mountains on the west and the Concord Mountains and Anare Mountains on the east, flowing to Ob' Bay on the coast and forming the Lillie Glacier Tongue.

Prince Charles Mountains mountain range

The Prince Charles Mountains are a major group of mountains in Mac. Robertson Land in Antarctica, including the Athos Range, the Porthos Range, and the Aramis Range. The highest peak is Mount Menzies. Other prominent peaks are Mount Izabelle and Mount Stinear. These mountains together with other scattered peaks form an arc about 260 miles long, extending from the vicinity of Mount Starlight in the north to Goodspeed Nunataks in the south.

Scott Mountains (Antarctica) mountain range in Antarctica

The Scott Mountains are a large number of isolated peaks lying south of Amundsen Bay in Enderby Land of East Antarctica, Antarctica. Discovered on 13 January 1930 by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Sir Douglas Mawson. He named the feature Scott Range after Captain Robert Falcon Scott, Royal Navy. The term mountains is considered more appropriate because of the isolation of its individual features.

Athos Range

Athos Range is the northernmost range in the Prince Charles Mountains of Mac. Robertson Land, Antarctica. The range consists of a large number of individual mountains and nunataks that trend east-west for 40 miles (60 km) along the north side of Scylla Glacier.

Wilma Glacier glacier in Antarctica

Wilma Glacier is the western of two glaciers entering the southern part of Edward VIII Ice Shelf in Kemp Land, East Antarctica. The second, eastern glacier is Robert Glacier.

The Doggers Nunataks are a group of peaks 30 nautical miles (60 km) southwest of Rayner Peak, to the southwest of Edward VIII Bay. They were photographed in October 1956 by Australian National Antarctic Research Expeditions (ANARE) aircraft and surveyed in December 1958 by G.A. Knuckey during a dog-sledge journey from Amundsen Bay to Mawson Station. The group was named by the Antarctic Names Committee of Australia for the members of the 1958 ANARE dog sledging party who were always referred to as the "Doggers."
