Ten-year progress of Chinese polar geodesy: 1996–2006

Abstract

The ten-year progress of Chinese polar geodesy from 1996 to 2006 is summarized. Research on plate motion, crustal movement, orbit determination, and atmospheric monitoring, including the ionosphere and troposphere, were performed using GPS data of the Great Wall Station, Zhongshan Station and Yellow River Station. GPS was also applied in the Amery Ice Shelf, Grove Mountains and Dome A expeditions to study ice dynamics. During the 2004/2005 austral summer season, the absolute gravity and relative gravity were measured at the Great Wall Station with precision within ± 3 × 10^-8 ms^-2 and ± 10 × 10^-8 ms^-2 respectively. The tide gauge, which was set up in Zhongshan Station to monitor sea level change in 2000, recorded the 2004 Indian Ocean tsunami. SAR interferometry was applied to build the DEM of ice sheet and monitor ice flow in the polar region.
