摘要: 利用由Seaset、Geosat、ERS-1和Topex/Poseidon卫星测高结果解算的2'×2'重力资料进行重力场分离,提取与海底地形起伏相关的重力异常,结合5'×5'ETOPO5海底地形资料进行反演,得到了中国海及邻域2'×2'高精度、高分辨率的海底地形结果。Abstract: This paper discriminates the 2'×2' gravity field,which is derived from altimetry satellite of Seaset,Geosat,ERS-1 and Topex/Poseidon,to elicit gravity anomaly correlated to sea floor.Using the gravity anomaly combined 5'×5' sea floor bathymetry data of ETOP5 to inversion,we can attain 2'×2' sea floor bathymetry result of China sea and its vicinity.
