Astrolabe Subglacial Basin

Astrolabe Subglacial Basin is a subglacial basin to the south of the Adélie Coast and east of Porpoise Subglacial Highlands, trending north–south and containing the thickest ice &mdash; about 4700 m &mdash; measured in Antarctica. The basin was delineated by the SPRI-NSF-TUD airborne radio echo sounding program, 1967–79, and named after the Astrolabe, the flagship of the French Antarctic Expedition, 1837–40, under Captain Jules Dumont d'Urville.
