The Astrolabe subglacial basin is a basin completely covered by glacier ice in the East Antarctic Adélieland, east of the Porpoise subglacial highlands . It extends in a north-south direction and with a thickness of 4700 m contains the thickest ice mass in Antarctica .
Its extent was determined by sonar tracking as part of a joint program of the Scott Polar Research Institute , the National Science Foundation and Denmark's Technical University between 1967 and 1979. It is named after the Astrolabe , one of the two ships used by polar explorer Jules Dumont d'Urville on the Third French Antarctic Expedition (1837-1840).
