Bellingshausen Sea in the context of "Ellsworth Land"

Peter I Island (Norwegian: Peter I Øy) is an uninhabited volcanic island in the Bellingshausen Sea, 450 kilometres (240 nmi) from continental Antarctica. It is claimed as a dependency of Norway and, along with Bouvet Island and Queen Maud Land, composes one of the three Norwegian dependent territories in the Antarctic and Subantarctic. The island measures approximately 11 by 19 kilometres (7 by 12 mi), with an area of 156 km (60 sq mi); its highest point is the ultra-prominent, 1,640-metre-tall (5,380 ft) Lars Christensen Peak. Nearly all the island is covered by a glacier, and it is surrounded most of the year by pack ice, making it inaccessible during these times. There is little vertebrate animal life on the island, apart from some seabirds and seals.

The island was first sighted by Fabian Gottlieb von Bellingshausen on 21 January 1821 and was named after Peter I of Russia. Not until 2 February 1929 did anyone set foot on the island, when Nils Larsen and Ola Olstad's Second Norvegia Expedition, financed by Lars Christensen, was successful. They claimed it for Norway, which annexed it in 1931 and made it a dependency in 1933. The next landing occurred in 1948, and the island has been subject to some scientific research and a limited amount of tourism. The island became subject to the Antarctic Treaty in 1961. Since 1987, there has been an automated meteorological station on the island. Three amateur radio DX-peditions have visited the island, and there are sporadic landings by tourists.

Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west. Alexander Island is about 390 kilometres (240 mi) long in a north–south direction, 80 kilometres (50 mi) wide in the north, and 240 kilometres (150 mi) wide in the south. Alexander Island is the second-largest uninhabited island in the world, after Devon Island.

Charcot Island or Charcot Land is an island administered under the Antarctic Treaty System, 56 kilometres (30 nmi) long and 46 kilometres (25 nmi) wide, which is ice covered except for prominent mountains overlooking the north coast. Charcot Island lies within the Bellingshausen Sea, 102 kilometres (55 nmi) west of Alexander Island, and about 57 kilometres (31 nmi) north of Latady Island. A notable landmark of the island is its northernmost point, Cape Byrd.

USS Glacier (AGB-4) (later USCGC Glacier (WAG/WAGB-4)) was a U.S. Navy, then U.S. Coast Guard icebreaker which served in the first through fifteenth Operation Deep Freeze expeditions. Glacier was the first icebreaker to make her way through the frozen Bellingshausen Sea, and most of the topography in the area is named for her crew members. When built, Glacier had the largest capacity single armature DC motors ever installed on a ship. Glacier was capable of breaking ice up to 20 feet (6.1 m) thick, and of continuous breaking of 4-foot (1.2 m) thick ice at 3 knots (5.6 km/h; 3.5 mph).

Named for Glacier Bay, Alaska, USS Glacier was launched on 27 August 1954 at Ingalls Shipbuilding Corp., Pascagoula, Mississippi, sponsored by Mrs. Roscoe F. Good; and commissioned on 27 May 1955, CDR. E.H. Mayer USN, Commanding. Glacier is the only icebreaker built in the Glacier class, and was in U.S. Navy service for 11 years, and U.S. Coast Guard service for 21 years.

Eights Coast is a portion of the coast of West Antarctica, between Cape Waite and Pfrogner Point. To the west is the Walgreen Coast, and to the east is the Bryan Coast. It is part of Ellsworth Land and stretches between 103°24'W and 89°35'W. This coast is bordered by Thurston Island, Abbot Ice Shelf and some islands within the ice shelf, and for most of its length touches the Bellingshausen Sea (west of Thurston Island by the Amundsen Sea). Most of Eights Coast is not claimed by any nation. In the east, Eights Coast borders the sector claimed by Chile as part of its southernmost province. Peter I Island, 450 kilometers (280 miles) north of the coast, is claimed by Norway as a dependency.

The coast was sighted by members of the US Antarctic Service by flights from the USS Bear during February 1940. It was mapped in detail by the United States Geological Survey from surveys and from U.S. Navy air photographs, 1960–1966. Eights Coast was named by the Advisory Committee on Antarctic Names for James Eights of Albany, New York, a geologist on the ship Annawan during 1830, who performed geological investigations of the South Shetland Islands, and who cruised westward on the Annawan, in company with the ship Penguin, to 103°W. Eights, the earliest American scientist in the Antarctic, discovered the first known fossils in the Antarctic region, a tree section in the South Shetland Islands. As a result of these investigations Eights, during 1833, published in the Transactions of the Albany Institute (Vol. 2) what proved to be remarkably accurate observations and conclusions concerning the natural phenomena of the region.

The Amundsen Sea is an arm of the Southern Ocean off Marie Byrd Land in western Antarctica. It lies between Cape Flying Fish (the northwestern tip of Thurston Island) 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.

The sea is mostly ice-covered, and the Thwaites Ice Tongue protrudes into it. The ice sheet which drains into the Amundsen Sea averages about 3 km (1.9 mi) in thickness; roughly the size of the state of Texas, this area is known as the Amundsen Sea Embayment (ASE); it forms one of the three major ice-drainage basins of the West Antarctic Ice Sheet.

Bryan Coast (73°35′S 84°0′W / 73.583°S 84.000°W / -73.583; -84.000 (Bryan Coast)) is that portion of the coast of Antarctica along the south shore of the Bellingshausen Sea between Pfrogner Point and the northern tip of the Rydberg Peninsula.To the west is Eights Coast, and to the east is English Coast.
