Sea gravity measurement in the Antarctic Research Expedition
Sea gravity measurements on board the icebreaker FUJI during the 22nd Japanese Antarctic Research Expedition conducted from November 1980 to April 1981 were very successful with almost no lack of measurements throughout the cruise. Free air and Bouguer gravity anomalies obtained at the continental s...

Sea gravity measurements on board the icebreaker FUJI during the 22nd Japanese Antarctic Research Expedition conducted from November 1980 to April 1981 were very successful with almost no lack of measurements throughout the cruise.

The Gunnerus Bank protruding from the Antarctic Continent is associated with free air gravity lows of -70 mgal at the foot of both sides.
