WebThe EAIS lies between 45° west and 168° east longitudinally. The EAIS holds enough ice to raise global sea levels by 53.3 m (175 ft) [1] and is considerably larger in area and mass than the West Antarctic Ice Sheet (WAIS). It is separated from the WAIS by the Transantarctic Mountains. WebHere, the ice sheet has been measured to be 4,897 metres (16,066 feet) thick. The basin is named after Astrolabe, the flagship of the French Antarctic Expedition (1837–40). Ice thickness is often measured using ice-penetrating radar, and many areas of Antarctica remain unsurveyed, which means that thicker ice could exist but has yet to be measured.
