Ellsworth Land in the context of "Cape Flying Fish"

Norway has three dependent territories (Norwegian: biland), all uninhabited and located in the Southern Hemisphere. Bouvet Island (Bouvetøya) is a sub-Antarctic island in the South Atlantic Ocean. Queen Maud Land is the sector of Antarctica between the 20th meridian west and the 45th meridian east. Peter I Island is a volcanic island located 450 kilometres (280 mi) off the coast of Ellsworth Land of continental Antarctica. Despite being unincorporated areas, neither Svalbard nor Jan Mayen is formally considered a dependency. While the Svalbard Treaty regulates some aspects of that Arctic territory, it acknowledges that the islands are part of Norway. Similarly, Jan Mayen is recognized as an integral part of Norway.

Both Peter I Island and Queen Maud Land are south of 60°S and are thus part of the Antarctic Treaty System. While the treaty does not affect these claims, the only states that recognize Norwegian sovereignty also have Antarctic claims. Administration of the dependencies is handled by the Polar Affairs Department of the Ministry of Justice and Public Security in Oslo. Norwegian criminal law, private law and procedural law apply to the dependencies, as do other laws that explicitly state they are valid on the dependencies.

The Chilean Antarctic Territory, or Chilean Antarctica (Spanish: Territorio Chileno Antártico, Antártica Chilena), is a part of West Antarctica and nearby islands claimed by Chile. It comprises the region south of 60°S latitude and between longitudes 53°W and 90°W, partially overlapping the Antarctic claims of Argentine Republic (Argentine Antarctica) and the United Kingdom (British Antarctic Territory). It constitutes the Antártica commune of Chile.

The territory covers the South Shetland Islands, the Antarctic Peninsula (called O'Higgins Land—Tierra de O'Higgins—in Chile), and the adjacent islands of Alexander Island, Charcot Island and Ellsworth Land, among others. Its boundaries are defined by Decree 1747, issued on 6 November 1940 and published on 21 June 1955 by the Ministry of Foreign Affairs:

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 Hudson Mountains are a mountain range in western Ellsworth Land just east of Pine Island Bay at the Walgreen Coast of the Amundsen Sea. They are of volcanic origin, consisting of low scattered mountains and nunataks that protrude through the West Antarctic Ice Sheet. The Hudson Mountains are bounded on the north by Cosgrove Ice Shelf and on the south by Pine Island Glacier. The mountains were volcanically active during the Miocene and Pliocene, but there is evidence for an eruption about two millennia ago and uncertain indications of activity in the 20th century.

The Jones Mountains (73°32′S 94°00′W / 73.533°S 94.000°W / -73.533; -94.000 (Jones Mountains)) are an isolated group of mountains, trending generally east–west for 27 nautical miles (50 km; 31 mi), situated on the Eights Coast, Ellsworth Land, Antarctica, about 50 nautical miles (93 km; 58 mi) south of Dustin Island.

The Behrendt Mountains (75°20′S 72°30′W / 75.333°S 72.500°W / -75.333; -72.500 (Behrendt Mountains)) is a group of mountains, 20 nautical miles (37 km; 23 mi) long, aligned in the form of a horseshoe with the opening to the southwest, standing 7 nautical miles (13 km; 8.1 mi) southwest of the Merrick Mountains in Ellsworth Land, Antarctica.

The Hauberg Mountains (75°52′S 069°15′W / 75.867°S 69.250°W / -75.867; -69.250 (Hauberg Mountains)) are a group of mountains of about 35 nautical miles (65 km; 40 mi) extent, located 12 nautical miles (22 km; 14 mi) north of Cape Zumberge and 30 nautical miles (56 km; 35 mi) south of the Sweeney Mountains in eastern Ellsworth Land, Antarctica.

The Merrick Mountains (75°06′S 72°04′W / 75.100°S 72.067°W / -75.100; -72.067 (Merrick Mountains)) are a cluster of mountains, 8 nautical miles (15 km; 9.2 mi) long, standing 7 nautical miles (13 km; 8.1 mi) northeast of the Behrendt Mountains in Ellsworth Land, Antarctica.

The Sweeney Mountains (75°06′S 069°15′W / 75.100°S 69.250°W / -75.100; -69.250 (Sweeney Mountains)) are a group of mountains of moderate height and about 40 nautical miles (74 km; 46 mi) extent, located 30 nautical miles (56 km; 35 mi) north of the Hauberg Mountains in eastern Ellsworth Land, Antarctica.
