Styggebrekka Crevasses

Last updated

Styggebrekka Crevasses is a crevasse field near the center of Austreskorve Glacier, in the Muhlig-Hofmann Mountains of Queen Maud Land. Plotted from surveys and air photos by Norwegian Antarctic Expedition (1956–60) and named Styggebrekka (the dangerous slope).

Crevasse A deep crack, or fracture, in an ice sheet or glacier

A crevasse is a deep crack, or fracture, found in an ice sheet or glacier, as opposed to a crevice that forms in rock. Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement. The resulting intensity of the shear stress causes a breakage along the faces.

Austreskorve Glacier glacier in Antarctica

Austreskorve Glacier is a broad glacier in the Mühlig-Hofmann Mountains which drains north from a position just east of the head of Vestreskorve Glacier and passes along the east side of Breplogen Mountain. It was mapped and named from surveys and from air photos by the Sixth Norwegian Antarctic Expedition (1956–60).

Queen Maud Land Norways territorial claim in Antarctica

Queen Maud Land is a c. 2.7 million square kilometre (1.04 million sq mi) region of Antarctica claimed as a dependent territory by Norway. The territory lies between 20° west and 45° east, between the claimed British Antarctic Territory to the west and the similarly claimed Australian Antarctic Territory to the east. On most maps there had been an unclaimed area between Queen Maud Land's borders of 1939 and the South Pole until 12 June 2015 when Norway formally annexed that area. Positioned in East Antarctica, the territory comprises about one-fifth of the total area of Antarctica. The claim is named after the Norwegian queen Maud of Wales (1869–1938).

United States Geological Survey scientific agency of the United States government

The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.

Geographic Names Information System geographical database

The Geographic Names Information System (GNIS) is a database that contains name and locative information about more than two million physical and cultural features located throughout the United States of America and its territories. It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names.

Coordinates: 71°58′S5°44′E / 71.967°S 5.733°E / -71.967; 5.733

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.

Northeast Glacier Antarctic glacier

Northeast Glacier is a steep, heavily crevassed glacier on the west side of Hemimont Plateau, 21 km (13 mi) long and 8 km (5 mi) wide at its mouth, which flows from McLeod Hill westward and then south-westwards into Marguerite Bay between the Debenham Islands and Roman Four Promontory, on the west coast of Graham Land, Antarctica. Northeast Glacier was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Riddoch Rymill. It was resurveyed in 1940 by members of the United States Antarctic Service (USAS), who first used the glacier as a sledging route, and so named by them because it lay on the north-eastern side of their base at Stonington Island.

Socks Glacier is a small glacier descending the east slopes of Queen Alexandra Range just north of Owen Hills to enter the west side of Beardmore Glacier. Discovered by the British Antarctic Expedition (1907–09) and named for one of the ponies taken with the South Pole Party. Socks, the last pony to survive the journey, fell into a crevasse on 7 December 1908, on Beardmore Glacier near Socks Glacier.

He is a computer and graphic specialist, and was part of the USGS team that compiled the 1:5,000,000-scale Advanced Very High Resolution Radiometer satellite image maps of Antarctica and the 1:250,000-scale Landsat image maps of the Siple Coast area in the 1990s.

Jutulstraumen Glacier is a large glacier in Queen Maud Land, Antarctica, about 120 nautical miles (220 km) long, draining northward to the Fimbul Ice Shelf between the Kirwan Escarpment, Borg Massif and Ahlmann Ridge on the west and the Sverdrup Mountains on the east.
