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.

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.

Paulding Bay bay

Paulding Bay is a bay along the coast of Antarctica just west of Clark Point. The outer portions of the bay are bounded by the Moscow University Ice Shelf and the Voyeykov Ice Shelf. It was mapped by G. D. Blodgett (1955) from aerial photographs obtained by USN Operation Highjump (1946–47), and named by the Advisory Committee on Antarctic Names (US-ACAN) for James K. Paulding, Secretary of the Navy under President Martin Van Buren. Paulding had previously served as U.S. Navy agent for New York and was instrumental in the outfitting of the United States Exploring Expedition (1838–42) under Lt. Charles Wilkes.
