Last updated

Mollweide Glacier ( 77°56′S163°40′E / 77.933°S 163.667°E / -77.933; 163.667 Coordinates: 77°56′S163°40′E / 77.933°S 163.667°E / -77.933; 163.667 ) is a steep glacier 1 nautical mile (2 km) south of Mount Kowalczyk, descending west from Hobbs Ridge into Blue Glacier, in Victoria Land, Antarctica. The name is one of a group in the area associated with surveying applied in 1993 by the New Zealand Geographic Board; this glacier was named from the Mollweide projection, an equal area map projection with the parallels and central meridian being straight lines.

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.

Mount Kowalczyk is a mountain, 1,690 metres (5,540 ft) high, standing 1 nautical mile (2 km) south of Goat Mountain at the head of Hobbs Glacier in Victoria Land, Antarctica. It was charted by the British Antarctic Expedition, 1910–13, under Robert Falcon Scott, and was named by the Advisory Committee on Antarctic Names in 1964 for Chester Kowalczyk, Chief of the Photogrammetry Branch, U.S. Naval Oceanographic Office, who for many years had responsibility for the photogrammetric compilation of Antarctic charts.

Suess Glacier is a glacier between Canada Glacier and Lacroix Glacier, flowing south into Taylor Valley in Victoria Land, Antarctica. It was charted and named by the British Antarctic Expedition under Scott, 1910–13, for Professor Eduard Suess, noted Austrian geologist and paleontologist.

Crescent Glacier (Antarctica) glacier in Antarctica

Crescent Glacier is a small alpine glacier in Antarctica. It is located just east of Howard Glacier in the Kukri Hills, flowing north into Taylor Valley in Victoria Land. The glacier was studied by U.S. geologist Troy L. Pewe in December 1957, and was so named by him because of its crescent shape when viewed from the floor of Taylor Valley.

Garwood Glacier glacier in Antarctica

Garwood Glacier is a glacier occupying the northwest part of Garwood Valley, in Victoria Land, Antarctica. It was first mapped by the British National Antarctic Expedition (1901–04), but was not named until 1911, when Thomas Griffith Taylor of the British Antarctic Expedition, 1910–13, named it for Edmund J. Garwood, professor of geology and mineralogy at the University of London.

Astapenko Glacier glacier in Antarctica

Astapenko Glacier is a glacier, 11 miles (18 km) long, draining the north and northeast slopes of Stanwix Peak in the Bowers Mountains and flowing east-northeast to Ob' Bay, situated in Victoria Land, Antarctica. It was mapped by the United States Geological Survey from surveys and from U.S. Navy air photos, 1960–62, and named by the Advisory Committee on Antarctic Names for Pavel D. Astapenko, Soviet IGY observer, a Weather Central meteorologist at Little America V in 1958. The glacier lies on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.

Erebus Glacier glacier in Antarctica

Erebus Glacier is a glacier draining the lower southern slopes of Mount Erebus, Ross Island, Antarctica. It flows west to Erebus Bay where it forms the floating Erebus Glacier Tongue. It was named in association with Mount Erebus by the British National Antarctic Expedition, 1901–04, under Robert Falcon Scott.

Blackwelder Glacier is a pocket glacier, 1 nautical mile (2 km) wide and 2 nautical miles (4 km) long, between Salmon Hill and Hobbs Glacier in Victoria Land. The glacier was studied during U.S. Navy Operation Deepfreeze, 1957–58, by Troy L. Pewe and was named by him for Eliot Blackwelder, former head of the Geology Department at Stanford University.

Bonne Glacier is a steep glacier 1 nautical mile (2 km) west-southwest of Hobbs Peak, descending northwest from Hobbs Ridge into Blue Glacier, in Victoria Land. The name is one of a group in the area associated with surveying applied in 1993 by the New Zealand Geographic Board. It was named after the Bonne map projection, a derivative conical projection, in which the parallels are spaced at true distances along meridians which are plotted as curves.

Cassini Glacier is a steep glacier between Goat Mountain and Bonne Glacier, descending northwest from Hobbs Ridge into Blue Glacier, in Victoria Land, Antarctica. One of a group of names in the area associated with surveying applied in 1993 by the New Zealand Geographic Board, it was named from the Cassini map projection, a cylindrical projection in which the cylinder is at right angles to the axis of the globe.

Confluence Cone is a small but conspicuous nunatak 4 nautical miles (7 km) southeast of Sickle Mountain, near the west coast of the Antarctic Peninsula. It was photographed from the air by the Ronne Antarctic Research Expedition in 1947. It was surveyed from the ground by the Falkland Islands Dependencies Survey in 1958, and so named by the UK Antarctic Place-Names Committee because of its position at the confluence of several glaciers which merge with Hariot Glacier to flow into the Wordie Ice Shelf.

The Cranfield Icefalls are a series of about eight spectacular icefalls, in an east-west line, falling steeply from Bucknell Ridge into the narrowest portion of Darwin Glacier near its mouth. The feature was named by the Darwin Glacier Party of the Commonwealth Trans-Antarctic Expedition (1956–58) for W.J. Cranfield, a member of the party.
