Information About

West Antarctica




The name has existed for more than 90 years (Balch, 1902; Nordenskiöld , 1905), but its greatest use followed the International Geophysical Year (1957-58) and explorations disclosing that the Transantarctic Mountains provide a useful regional separation of West Antarctica and East Antarctica . The name was approved by Advisory Committee On Antarctic Names (US-ACAN) in 1962.
