There is a strong link between SCAR and IAG bodies in promoting long-term efforts to close the continental-wide data gaps that still remain in terrestrial gravity coverage over Antarctica. Airborne gravimetry provides the only feasible technique to survey large areas. A variety of aerogravity surveys have been accomplished, and several new ones are planned within the framework of the International Polar Year 2007/2008. In the Antarctic Peninsula region, the British Antarctic Survey has carried out a number of airborne and terrestrial gravity surveys. We have determined the regional geoid for Palmer Land, since a recent aerogeophysical survey provideshigh-quality and homogeneous gravity data. To improve the regional geoid  the Remove-Compute-Restore technique is applied, where long-wavelength information from a global satellite-derived gravity field model and short-wavelength information from topography are utilized. Our regional geoid improvement adds a threshold of about 5m to the global model and shows several new details.
