利用TOPEX资料可以得到新的地球引力场、海洋大地水准面和海潮模型。

Using TOPEX altimeter data, a few new earth gravity models, geoid models and ocean tide models were generated, and these models were better than old models.

这个新的大地水准面地图对于研究海洋环流、海冰动力学，海平面变化和地震会是有用的。

The new geoid map will be useful for studying ocean circulation, ice dynamics, sea-level change and earthquakes.
