Enderby Plain

Last updated

Enderby Plain (also known as Enderby Abyssal Plain or East Abyssal Plain) ( 60°S40°E / 60°S 40°E / -60; 40 Coordinates: 60°S40°E / 60°S 40°E / -60; 40 ) is an undersea plain (or abyssal plain ), located off the coast of Enderby Land and Queen Maud Land, East Antarctica. The name was approved by the U.S. Board on Geographic Names Advisory Committee on Undersea Features in June 1988. [1]

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.

Abyssal plain Flat area on the deep ocean floor

An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 metres (9,800 ft) and 6,000 metres (20,000 ft). Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth’s surface. They are among the flattest, smoothest, and least explored regions on Earth. Abyssal plains are key geologic elements of oceanic basins.

Enderby Land geographical object

Enderby Land is a projecting land mass of Antarctica. Its shore extends from Shinnan Glacier at about 67°55′S44°38′E to William Scoresby Bay at 67°24′S59°34′E, approximately ​124 of the earth's longitude. It was first documented in western and eastern literature in February 1831 by John Biscoe aboard the whaling brig Tula, and named after the Enderby Brothers of London, the ship's owners who encouraged their captains to combine exploration with sealing.

This submarine terrain feature is named after the Enderby Brothers, owners of a 19th-century whaling company based in London, England. The company sponsored several expeditions to Antarctica in the mid-19th century.

Samuel Enderby & Sons was a whaling and sealing company based in London, England, founded circa 1775 by Samuel Enderby (1717–1797). The company encouraged their captains to combine exploration with their business activities, and sponsored several of the earliest expeditions to the subantarctic, Southern Ocean and Antarctica itself.

Whaling hunting of whales

Whaling is the hunting of whales for their usable products such as meat and blubber, which can be turned into a type of oil which became increasingly important in the Industrial Revolution. It was practiced as an organized industry as early as 875 AD. By the 16th century, it had risen to be the principle industry in the coastal regions of Spain and France. The industry spread throughout the world, and became increasingly profitable in terms of trade and resources. Some regions of the world's oceans, along the animals' migration routes, had a particularly dense whale population, and became the targets for large concentrations of whaling ships, and the industry continued to grow well into the 20th century. The depletion of some whale species to near extinction led to the banning of whaling in many countries by 1969, and to a worldwide cessation of whaling as an industry in the late 1980s. The earliest forms of whaling date to at least circa 3000 BC. Coastal communities around the world have long histories of subsistence use of cetaceans, by dolphin drive hunting and by harvesting drift whales. Industrial whaling emerged with organized fleets of whaleships in the 17th century; competitive national whaling industries in the 18th and 19th centuries; and the introduction of factory ships along with the concept of whale harvesting in the first half of the 20th century. By the late 1930s more than 50,000 whales were killed annually. In 1986, the International Whaling Commission (IWC) banned commercial whaling because of the extreme depletion of most of the whale stocks.

Antarctica Polar continent in the Earths southern hemisphere

Antarctica is Earth's southernmost continent. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,000,000 square kilometres, it is the fifth-largest continent. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.

Beaver Glacier is a glacier about 15 miles (24 km) long and 4 miles (6 km) wide, flowing west into Amundsen Bay between Auster Glacier and Mount Gleadell. The head of Beaver Glacier is located very close to the base of Mount King in Enderby Land. It was visited by an Australian National Antarctic Research Expeditions (ANARE) party on October 28, 1956, and named after the Beaver aircraft used by ANARE in coastal exploration.

Scott Mountains (Antarctica) mountain range in Antarctica

The Scott Mountains are a large number of isolated peaks lying south of Amundsen Bay in Enderby Land of East Antarctica, Antarctica. Discovered on 13 January 1930 by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Sir Douglas Mawson. He named the feature Scott Range after Captain Robert Falcon Scott, Royal Navy. The term mountains is considered more appropriate because of the isolation of its individual features.
