The Cronk Islands are a group of Antarctic islands lying northeast of Hollin Island, in the Windmill Islands. They were first mapped from air photos taken by USN Operation Highjump in 1946 and 1947. They were named by the US-ACAN for Caspar Cronk, glaciologist at Wilkes Station in 1958.

Antarctic region around the Earths South Pole

The Antarctic is a polar region around the Earth's South Pole, opposite the Arctic region around the North Pole. The Antarctic comprises the continent of Antarctica, the Kerguelen Plateau and other island territories located on the Antarctic Plate or south of the Antarctic Convergence. The Antarctic region includes the ice shelves, waters, and all the island territories in the Southern Ocean situated south of the Antarctic Convergence, a zone approximately 32 to 48 km wide varying in latitude seasonally. The region covers some 20 percent of the Southern Hemisphere, of which 5.5 percent is the surface area of the Antarctic continent itself. All of the land and ice shelves south of 60°S latitude are administered under the Antarctic Treaty System. Biogeographically, the Antarctic ecozone is one of eight ecozones of the Earth's land surface.

Hollin Island

Hollin Island is an Antarctic island about 1.9 kilometres (1 nmi) long, lying north of Midgley Island, in the Windmill Islands. It was first mapped from air photos taken by USN Operation Highjump in 1946 and 1947. It was named by the US-ACAN for John T. Hollin, glaciologist at Wilkes Station in 1958.

Windmill Islands island

The Windmill Islands are an Antarctic group of rocky islands and rocks about 11.1 kilometres (6 nmi) wide, paralleling the coast of Wilkes Land for 31.5 kilometres (17 nmi) immediately north of Vanderford Glacier along the east side of Vincennes Bay. Kirkby Shoal is a small shoal area with depths of less than 18 metres (59 ft) extending about 140 metres (459 ft) westwards and SSW, about 3.4 kilometres (2.1 mi) from the summit of Shirley Island, Windmill Islands, and 0.24 kilometres (0.15 mi) NW of Stonehocker Point, Clark Peninsula.

Territorial claims in Antarctica Wikimedia list article

There are seven sovereign states who currently maintain de jure, largely symbolic territorial claims in Antarctica: Argentina, Australia, Chile, France, New Zealand, Norway and the United Kingdom. These countries have tended to place their Antarctic scientific observation and study facilities within their respective claimed territories; however, a number of such facilities are located nowhere near the sectors claimed by their respective countries of operation, and there are multiple other countries such as Russia and the United States who, despite having no territorial claim of their own anywhere in Antarctica, have constructed large research facilities within the sectors claimed by other countries.

Elephant Island island off the coast of Antarctica

Elephant Island is an ice-covered mountainous island off the coast of Antarctica in the outer reaches of the South Shetland Islands, in the Southern Ocean. Its name was given by early explorers sighting elephant seals on its shores. The island is situated 245 kilometres north-northeast of the tip of the Antarctic Peninsula, 1,253 kilometres west-southwest of South Georgia, 935 kilometres south of the Falkland Islands, and 885 kilometres southeast of Cape Horn. It is within the Antarctic claims of Argentina, Chile and the UK. Brazil has a shelter on the island, Goeldi, supporting the work of up to six researchers each during the summer and had another (Wiltgen), which was dismantled in the summer of 1997/98.

They have a total area of about 620 square kilometres (240 sq mi). The islands are claimed both by Britain, and by Argentina as part of Argentine Antarctica. Under the 1959 Antarctic Treaty, sovereignty claims are held in abeyance.

It was charted by the Belgian Antarctic Expedition under Adrien de Gerlache, 1897–1899. Danco Island was surveyed by the Falkland Islands Dependencies Survey from Norsel in 1955, and named by the UK Antarctic Place-names Committee for Emile Danco (1869–1898), a Belgian geophysicist and member of the Belgian Antarctic Expedition, who died on board Belgica in the Antarctic.

Flask Glacier glacier in Antarctica

Flask Glacier, is a gently-sloping glacier, 25 nautical miles long, flowing east from Bruce Plateau to enter Scar Inlet between Daggoo Peak and Spouter Peak in Graham Land, Antarctica. The lower reaches of this glacier were surveyed and photographed by the Falklands Islands Dependencies Survey (FIDS) in 1947. The entire glacier was photographed by the Falkland Islands and Dependencies Aerial Survey Expedition in 1955–56, and mapped by the FIDS in 1957. It was named by the UK Antarctic Place-names Committee after the third mate on the Pequod in Herman Melville's Moby-Dick; or, The White Whale.

Ardley Island island in Antarctica

Ardley Island is an island 1.9 kilometres (1 nmi) long, lying in Maxwell Bay close off the south-west end of King George Island, in the South Shetland Islands of Antarctica. It was charted as a peninsula in 1935 by Discovery Investigations personnel of the Discovery II and named for Lieutenant R.A.B. Ardley, Royal Naval Reserve, an officer on the ship in 1929–31 and 1931–33. Aerial photography has since shown that the feature is an island with Braillard Point being the headland forming the northeast end of Ardley Island. It has been designated an Antarctic Specially Protected Area because of the importance of its seabird colonies.
