Mitchell Glacier

Last updated

Mitchell Glacier is a glacier which descends steeply from Chaplains Tableland in the northeast of the Royal Society Range, Victoria Land, Antarctica, flowing east-northeast between Transit Ridge and Ibarra Peak to join the Blue Glacier drainage south of the Granite Knolls. It was named by the Advisory Committee on Antarctic Names in 1992 after J. Murray Mitchell, a climatologist with the U.S. Weather Bureau and successor agencies from 1955 to 1986. From 1974 onwards he played a significant part in the Polar Research Board of the National Academy of Sciences, and the Division of Polar Programs of the National Science Foundation. [1]

Glacier Persistent body of ice that is moving under its own weight

A glacier is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques and moraines. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.

Chaplains Tableland is a high tableland just north of Mount Lister in the Royal Society Range. It was named by the Advisory Committee on Antarctic Names in 1963 in honor of the chaplains who have served in Antarctica, primarily at McMurdo Station. The feature is clearly visible from McMurdo Station.

Royal Society Range mountain range

The Royal Society Range is a majestic mountain range in Victoria Land, Antarctica. With its summit at 4,025 metres (13,205 ft), the massive Mount Lister forms the highest point in this range. Mount Lister is located along the western shore of McMurdo Sound between the Koettlitz, Skelton and Ferrar glaciers. Other notable local terrain features include Allison Glacier, which descends from the west slopes of the Royal Society Range into Skelton Glacier.

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.
