Last updated

Dvořák Ice Rise ( 71°21′S72°46′W / 71.350°S 72.767°W / -71.350; -72.767 Coordinates: 71°21′S72°46′W / 71.350°S 72.767°W / -71.350; -72.767 ) is an ice rise 1.5 nautical miles (3 km) in extent, rising above the ice of Mendelssohn Inlet in the southwest part of Alexander Island, Antarctica. It was first mapped, from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960, and was named by the UK Antarctic Place-Names Committee after Antonín Dvořák, the Czech composer. [1] (1841-1904).

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.

Ice rise an elevation of the otherwise totally flat ice shelf

An ice rise is a clearly defined elevation of the otherwise totally flat ice shelf, typically dome-shaped and rising 100 to 200 metres above the surrounding ice shelf. An ice rise forms where the ice shelf touches the rocky seabed because of an elevation in the seabed that remains below sea level.. The ice shelf flows over the seabed elevation, completely covering it with ice, thereby forming an ice rise. The resulting tension forms crevasses around the ice rise.

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.

Hemmen Ice Rise is an ice rise 11 miles (18 km) long and 2 to 4 kilometres wide, with an estimated area of 55 square kilometres (21 sq mi), located 17 kilometres (11 mi) off the northwest corner of Berkner Island in the Ronne Ice Shelf, Antarctica.
