水下重力测量技术进展

首先介绍了水下重力测量的概念，阐述了水下重力测量的必要性；然后简要概述了水下重力测量技术的发展历程，比较了现有的两种主流测量方案（ROV水下重力测量和AUV水下重力测量）的优缺点，重点介绍了国内外水下重力测量近期的技术进展，包括加州大学基于二级拖体ROV的水下近海底重力测量试验和东京大学的AUV水下动态重力测量系列试验；最后分析了水下动态重力测量的研究重点并指出了其后续发展方向。

Development of underwater gravity measurement technologies

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.
