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.

David Island is an ice-covered island, 10 miles (16 km) long and 6 miles (10 km) wide, marked by rock exposures along its north and east sides, lying off Davis Peninsula in the Shackleton Ice Shelf in Antarctica. It was discovered in November 1912 by the Western Base party of the Australasian Antarctic Expedition (AAE) under Mawson, and named by him for Professor Sir T.W. David Hunt, a member of the AAE Advisory Committee.

Australasian Antarctic Expedition research expedition

The Australasian Antarctic Expedition (AAE) was an Australasian scientific team that explored part of Antarctica between 1911 and 1914. It was led by the Australian geologist Douglas Mawson, who was knighted for his achievements in leading the expedition. In 1910 he began to plan an expedition to chart the 3,200-kilometre-long (2,000 mi) coastline of Antarctica to the south of Australia. The Australasian Association for the Advancement of Science approved of his plans and contributed substantial funds for the expedition.

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.

Hudson Strait links the Atlantic Ocean and Labrador Sea to Hudson Bay in Canada. This strait lies between Baffin Island and Nunavik, with its eastern entrance marked by Cape Chidley in Newfoundland and Labrador and Resolution Island off Baffin Island. The strait is about 750 km long with an average width of 125 km, varying from 70 km at the eastern entrance to 240 km at Deception Bay.

Belmiro Braga is a city in the state of Minas Gerais, Brazil close to the border with Rio de Janeiro state. It was emancipated from Juiz de Fora in 1962. Population: 3,600 inhabitants.

Cape Hordern is an ice-free cape, overlain by morainic drift, at the northwest end of the Bunger Hills in Antarctica. It was probably sighted from Watson Bluff by A.L. Kennedy and other members of the Western Base Party of the Australasian Antarctic Expedition under Mawson, 1911–14, who charted the west wall of what appeared to be two small islands lying north of Cape Hoadley in about 100°35′E. It was named "Hordern Island" by Mawson for Sir Samuel Hordern of Sydney, a patron of the expedition. It was renamed Cape Hordern by the Advisory Committee on Antarctic Names (US-ACAN) following correlation of Kennedy's map with the US-ACAN map of 1955 compiled from aerial photographs taken by U.S. Navy Operation Highjump, 1946–47.

Shadow Bluff is a rock bluff in Antarctica, just west of McGregor Range, at the junction of the Tucker and Leander Glaciers. It is a landmark when sledging on the Tucker Glacier, and is nearly always in shadow, hence the name. Named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1957-58.

Shell Glacier is a western lobe of the Mount Bird icecap. It descends steeply in the valley north of Trachyte Hill and Harrison Bluff in the center of the ice-free area on the lower western slopes of Mount Bird, Ross Island. Mapped and so named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1958–59, because of the marine shell content of the moraines.

The Baldwin Rocks are a group of rock outcrops about 5 nautical miles (10 km) northwest of Watson Bluff on the north side of David Island. They were charted by the Australasian Antarctic Expedition, 1911–14, under Mawson, and named by him for Joseph M. Baldwin of the Melbourne Observatory.

Canyon Glacier is a narrow glacier, 35 nautical miles (65 km) long, flowing to the Ross Ice Shelf. It drains the northwest slopes of Mount Wexler and moves northward between steep canyon walls of the Separation Range and Hughes Range to join the ice shelf immediately west of Giovinco Ice Piedmont. The glacier was observed from nearby Mount Patrick by the New Zealand Alpine Club Antarctic Expedition (1959–60) who gave the descriptive name.

Coalsack Bluff is a small rock bluff standing at the northern limits of Walcott Neve, 6 nautical miles (11 km) west-southwest of Bauhs Nunatak. It was so named by the New Zealand Geological Survey Antarctic Expedition (1961–62) because of the coal seams found running through the bluff.

Commandant Charcot Glacier

Commandant Charcot Glacier is a prominent glacier about 3 nautical miles (6 km) wide and 12 nautical miles (22 km) long, flowing north-northwest from the continental ice to its terminus at the head of Victor Bay. It was delineated from aerial photographs taken by U.S. Navy Operation Highjump, 1946–47. The French Antarctic Expedition, 1950–1952, under Mario Marret sledged west along the coast to Victor Bay, close east of this glacier, in December 1952, and it was named by them for the polar ship Commandant Charcot which transported French expeditions to this area, 1948–1952.
