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.

Mendelssohn Inlet is an ice-filled inlet, 25 nautical miles (46 km) long and 9 nautical miles (17 km) wide, situated between Derocher Peninsula and Eroica Peninsula on the north side of Beethoven Peninsula, in the southwest part of Alexander Island, Antarctica. The inlet was first sighted from the air and roughly mapped by the United States Antarctic Service, 1939–41, and was resighted and photographed from the air by the Ronne Antarctic Research Expedition (RARE), 1947–48. It was remapped from the RARE photos by D. Searle of the Falkland Islands Dependencies Survey in 1960, and named by the UK Antarctic Place-Names Committee after German composer Felix Mendelssohn.

Beethoven Peninsula

The Beethoven Peninsula is a deeply indented, ice-covered peninsula, 60 miles (100 km) long in a northeast-southwest direction and 60 miles (100 km) wide at its broadest part, forming the southwest part of Alexander Island, which lies off the southwestern portion of the Antarctic Peninsula. The south side of the peninsula is supported by the Bach Ice Shelf whilst the north side of the peninsula is supported by the Wilkins Ice Shelf. The Mendelssohn Inlet, the Brahms Inlet and the Verdi Inlet apparently intrude into it. The Bach Ice Shelf, Rossini Point and Berlioz Point are some distance away, on the Ronne Entrance from the Southern Ocean. Beethoven Peninsula is one of the eight peninsulas of Alexander Island.

Alexander Island island in the Bellingshausen Sea off Antarctica

Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west.
