Maud Seamount ( 65°0′S2°35′E / 65.000°S 2.583°E / -65.000; 2.583 Coordinates: 65°0′S2°35′E / 65.000°S 2.583°E / -65.000; 2.583 ) is a seamount in the Southern Ocean. Its name was approved by the Advisory Committee for Undersea Features in February 1964. [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.

Seamount A mountain rising from the ocean seafloor that does not reach to the waters surface

A seamount is a mountain rising from the ocean seafloor that does not reach to the water's surface, and thus is not an island, islet or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000–4,000 m (3,300–13,100 ft) in height. They are defined by oceanographers as independent features that rise to at least 1,000 m (3,281 ft) above the seafloor, characteristically of conical form. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea. During their evolution over geologic time, the largest seamounts may reach the sea surface where wave action erodes the summit to form a flat surface. After they have subsided and sunk below the sea surface such flat-top seamounts are called "guyots" or "tablemounts"

Southern Ocean The ocean around Antarctica

The Southern Ocean, also known as the Antarctic Ocean or the Austral Ocean, and the "Southern Icy Ocean".</ref> comprises the southernmost waters of the World Ocean, generally taken to be south of 60° S latitude and encircling Antarctica. As such, it is regarded as the fourth largest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian Oceans but larger than the Arctic Ocean. This ocean zone is where cold, northward flowing waters from the Antarctic mix with warmer subantarctic waters.

Belgica Mountains mountain range

Belgica Mountains is an isolated chain of mountains about 10 miles (16 km) long, standing 60 miles (97 km) east-southeast of the Sor Rondane Mountains in Queen Maud Land, in the Antarctic. The chain was discovered by the Belgian Antarctic Expedition (1957-1958) under Gaston de Gerlache, and named after the ship Belgica, commanded by his father, Lt. Adrien de Gerlache, leader of the Belgian Antarctic Expedition of 1897-99. The Prince de Ligne Mountains stand about 10 mi (16 km) north of the Belgica Mountains.

Blodgett from aerial photographs taken by U.S. Navy Operation Highjump in 1947 and named by Advisory Committee on Antarctic Names (US-ACAN) after Lieutenant Thomas Joseph Underwood, Jr., USMC, who served on the sloop Vincennes of the United States Exploring Expedition (1838–42) under Lieutenant Charles Wilkes.

Explorers Range

Explorers Range is a large mountain range in the Bowers Mountains of Victoria Land, Antarctica, extending from Mount Bruce in the north to Carryer Glacier and McLin Glacier in the south. Named by the New Zealand Antarctic Place-Names Committee (NZ-APC) for the northern party of New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1963–64, whose members carried out a topographical and geological survey of the area. The names of several party members are assigned to features in and about this range. All of the geographical features listed below lie situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.

Lazarev, commanding officer of the sloop Mirnyy during the Bellingshausen expedition of 1819–1821. The name, proposed by Dr. G. Agapova of the Geological Institute of the Russian Academy of Sciences, was approved by the Advisory Committee for Undersea Features in August 1985.
