Sirius Islands ( 66°57′S57°27′E / 66.950°S 57.450°E / -66.950; 57.450 Coordinates: 66°57′S57°27′E / 66.950°S 57.450°E / -66.950; 57.450 ) is a chain of islands in the north part of the Oygarden Group. Mapped by Norwegian cartographers from aerial photos taken by the Lars Christensen Expedition, 1936–37, and called Nordoyane (the north islands). The group was first visited by an ANARE (Australian National Antarctic Research Expeditions) party in 1954; this chain was renamed by Antarctic Names Committee of Australia (ANCA) after the star Sirius which was used for an astrofix in the vicinity.

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.

The Australian National Antarctic Research Expeditions is the historical name for the Australian Antarctic Program (AAp) administered for Australia by the Australian Antarctic Division (AAD).

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.

Cape Filchner is an ice-covered cape fronting on Davis Sea, 17 miles west-northwest (WNW) of Adams Island. Cape Filchner is located at 66°27′S 91°54′E. Cape Filchner is the division between Wilhelm II Coast and Queen Mary Coast. Cape Filchner was discovered by the Australian Antarctic Expedition (1911-1914) under Sir Douglas Mawson, who named it for Wilhelm Filchner, leader of the German Antarctic Expedition of 1911-1912.

The French Antarctic Expedition is any of several French expeditions in Antarctica.

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.

Hanusse Bay is a broad bay, 37 kilometres (20 nmi) long in a general north-south direction, lying between the northern portions of Adelaide Island and Arrowsmith Peninsula, Antarctica. The bay was discovered and first charted by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, and named by him for the director of the Hydrographic Service of the French Navy Ferdinand Isidore Hanusse (1848–1921).

Hag Pike is a conspicuous rock column, 710 metres (2,330 ft) high, on the north side of the Wordie Ice Shelf near the west coast of the Antarctic Peninsula. Together with the mountain to the north, it forms the west side of the mouth of Hariot Glacier. Hag Pike was photographed from the air by the British Graham Land Expedition, 1937, and by the Ronne Antarctic Research Expedition, 1947. It was surveyed by the Falkland Islands Dependencies Survey, 1948–50, and 1958. The name by the UK Antarctic Place-Names Committee is descriptive, "hag" being the stump of a tree which remains after felling.

Alphard Island

Alphard Island or Meøya is an island 4.6 kilometres (2.5 nmi) long and rising to 150 metres (500 ft), lying north of Shaula Island in the Øygarden Group.

It was first visited by an Australian National Antarctic Research Expeditions party led by R. Dovers in 1954; the island was renamed by the Antarctic Names Committee of Australia after the star Alphard, which was used for an astrofix in the vicinity.

The Barcroft Islands are a group of small islands and rocks about 5 miles (8 km) in extent, lying close south of Watkins Island, Biscoe Islands.
