Cape Polar Star ( 73°38′S169°40′E / 73.633°S 169.667°E / -73.633; 169.667 Coordinates: 73°38′S169°40′E / 73.633°S 169.667°E / -73.633; 169.667 ) is a bold cape which forms the southwest extremity of Coulman Island in northwestern Ross Sea. Named by Advisory Committee on Antarctic Names (US-ACAN) in 1987 after USCGC activities in Antarctica, including the Ross Sea, since Operation Deep Freeze, 1978. A survey of this feature was conducted from Polar Star in 1986.

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.

Coulman Island island in Victoria Land, Antarctica

Coulman Island is an ice-covered island, composed of several connected shield volcanos in the Ross Sea off Antarctica. It is 33.3 kilometres (18 nmi) long and 14.8 kilometres (8 nmi) and is located 17 kilometres (9 nmi) SE of Cape Jones, Victoria Land. The Coulman caldera, 4.8 kilometres (3 mi) wide and 701 metres (2,300 ft) deep, can be found on the south end of the island. Emperor penguins inhabit this island. Coulman Island lies within the boundaries of Ross Dependency, which is claimed by New Zealand; a claim unrecognised by most other states. It was discovered in 1841 by Sir James Clark Ross who named it for his father-in-law, Thomas Coulman. A notable landmark of this island is Cape Anne, the south-easternmost point of the island, so named by Sir James Clark Ross for his wife. Cape Wadworth is the northernmost point of the island.

Ross Sea A deep bay of the Southern Ocean in Antarctica

The Ross Sea is a deep bay of the Southern Ocean in Antarctica, between Victoria Land and Marie Byrd Land and within the Ross Embayment, and is the southernmost sea on Earth. It derives its name from the British explorer James Ross who visited this area in 1841. To the west of the sea lies Ross Island and Victoria Land, to the east Roosevelt Island and Edward VII Peninsula in Marie Byrd Land, while the southernmost part is covered by the Ross Ice Shelf, and is about 200 miles (320 km) from the South Pole. Its boundaries and area have been defined by the New Zealand National Institute of Water and Atmospheric Research as having an area of 637,000 square kilometres (246,000 sq mi).

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.

The Amundsen Sea, an arm of the Southern Ocean off Marie Byrd Land in western Antarctica, lies between Cape Flying Fish to the east and Cape Dart on Siple Island to the west. Cape Flying Fish marks the boundary between the Amundsen Sea and the Bellingshausen Sea. West of Cape Dart there is no named marginal sea of the Southern Ocean between the Amundsen and Ross Seas. The Norwegian expedition of 1928–1929 under Captain Nils Larsen named the body of water for the Norwegian polar explorer Roald Amundsen while exploring this area in February 1929.

Borchgrevink Glacier glacier in Antarctica

Borchgrevink Glacier is a large glacier in the Victory Mountains, Victoria Land, draining south between Malta Plateau and Daniell Peninsula, and thence projecting into Glacier Strait, Ross Sea, as a floating glacier tongue, the Borchgrevink Glacier Tongue, just south of Cape Jones. It was named by the New Zealand Geological Survey Antarctic Expedition, 1957–58, for Carsten Borchgrevink, leader of the British Antarctic Expedition, 1898–1900. Borchgrevink visited the area in February 1900 and first observed the seaward portion of the glacier.
