Gravity Measurement on Board the Icebreaker 'Fuji' During the Japanese Antarctic Research Expedition, 1980-1981

Abstract

A newly designed surface ship gravity meter named 'NIPRORI' was installed on board the icebreaker 'Fuji' for the 22nd Japanese Antarctic Research Expedition (JARE-22). The icebreaker started from Tokyo, Japan on November 25, 1980, and reached Lützow-Holm Bay of the Antarctica on January 2, 1981. In February, 1981 she left the Antarctica, and returned to Tokyo on April 20. Gravity measurement at sea near the East Antarctica using this gravity meter was successfully conducted, with almost no lack of the measurement throughout the cruise.
