Abstract

Abstract: This paper introduces the concept of underwater gravity measurement at first, and then analyzes the necessity of underwater gravity measurement. It briefly illustrates its whole development history in the second part, in which the advantages and disadvantages of two mainstream schemes, including underwater gravity measurement based on ROV and underwater gravity measurement based on AUV, are discussed. In the third part, we introduce the latest development at home and abroad, typically including the near-bottom gravimetry based on a cas-cade connected ROV named TOWDOG, from University of California, and a series of underwater gravimetry using AUV,from the University of Tokyo. At last, it presents the research emphases and the near future development of this field in China.

Key words: earth gravity field, underwater gravity measurement, marine gravity measurement, gravimeter, development
