摘　　要：1.Introduction Gravity data provide significant insights on ice mass balance and geological structure studies in Antarctica,which is the largest ice sheet on the earth(Xu,2001;Alley et al.,2005).Since the 1950s,the gravity ties have been introduced to Antarctica from Australia and South America(Sledzinski,2001;Amalvict,2004),which adopted the approach of relative gravity measurements with pendulum or spring gravimeters.Absolute gravity measurements were later conducted in Antarctica by several countries to provide gravity bases and to derive its dynamic change with the technique advance in gravimeter instrumentation.By 2009,25 absolute gravity surveys had been carried out at 14 stations in Antarctica(Mäkinen et al.,2007;E et al.,2007,2011;Kazama et al.,2013).
