The Belgica-Guyot is a remote guyot (table mountain -like deep sea mountain ) in the southern ocean north of the Bellingshausen Sea . It belongs to the De-Gerlache-Seamounts , whose second prominent representative, the Lecointe-Guyot , is 125 km to the north-west.

The Belgica-Guyot is located about 340 km northeast of the Dallmann Seamount , 370 km north of Peter I Island and 740 km northeast of Thurston Island off the Eights coast of West Antarctica . At its base it is 90 km long in north-south direction and 60 km wide in east-west direction. Its steep flanks rise more than 4000 meters to a 600 km² plateau, which is 390 to 600 m below sea level. This plateau is 46 km long and 17 km wide.

The guyot was discovered in 1970 on a research voyage of the USNS Eltanin , a survey ship of the United States Navy . In 1995 it was systematically examined by the crew of the German research vessel Polarstern . It was named at the suggestion of Rick Hagen from the Alfred Wegener Institute . This was recognized in July 1997 by the US Advisory Committee for Undersea Features . It is named after the Belgica , the ship of the Antarctic expedition of the same name (1897–1899) of the Belgian polar explorer Adrien de Gerlache de Gomery .
