Fowler Ice Rise

Last updated

Fowler Ice Rise ( 77°30′S78°0′W / 77.500°S 78.000°W / -77.500; -78.000 Coordinates: 77°30′S78°0′W / 77.500°S 78.000°W / -77.500; -78.000 ) is a very large Antarctic ice rise between Evans Ice Stream and Carlson Inlet, in the southwest part of the Ronne Ice Shelf. The feature appears to be completely ice-covered except for the Haag Nunataks, which protrude above the surface in the northwestern portion. It was mapped by the United States Geological Survey from Landsat imagery taken 1973–74, and named by the Advisory Committee on Antarctic Names for Captain Alfred N. Fowler, U.S. Navy, Commander of the U.S. Naval Support Force, Antarctica, 1972–74. [1]

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.

Antarctica Polar continent in the Earths southern hemisphere

Antarctica is Earth's southernmost continent. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,000,000 square kilometres, it is the fifth-largest continent. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.

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.

Foundation Ice Stream is a major ice stream in Antarctica's Pensacola Mountains. The ice stream drains northward for 150 nautical miles along the west side of the Patuxent Range and the Neptune Range to enter the Ronne Ice Shelf westward of Dufek Massif. The United States Geological Survey mapped the stream from surveys and U.S. Navy air photos, 1956–66. The Advisory Committee on Antarctic Names named the stream in recognition of the National Science Foundation, which provided major support to the U.S. Antarctic Research Program during this period.

It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–52) and air photos by the Norwegian expedition (1958–59) and named Jutulstraumen. More specifically jutulen are troll-like figures from Norwegian folk tales. The ice stream reaches speeds of around 4 metres per day near the coast where it is heavily crevassed.
