中国海及邻近海域2′×2′海底地形

2′× 2′ Sea Floor Bathymetry Prediction of China Sea and Its Vicinity

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。

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.
