Gravity measurements, combined with precise positioning measurements and satellite gravity measurements, are necessary to separate the effects of past and present deglaciations on the variation of the Earth's gravity field. During the International Polar Year, we will make absolute gravity measurements at 6 stations in Antarctica. This program is the follow-up of measurements made at the Dumont D'Urville station, in Terre Adlie, in 2000 and 2006. It will be followed by another measurement at Dumont D'Urville station in 2010.
