海洋重力资料数字处理方法与程序

随着海洋重力测量技术的发展和重力仪器的更新换代,重力资料的数字处理已成为重力勘探中的一个重要组成部分。本文着重介绍KSS—5型海洋重力仪采集的重力资料在RDS 500及CYBER 172计算机上进行布伽、厄特维斯、正常场等项校正的数字处理及座标转换,最终绘出海洋重力综合剖面图及布伽异常图的方法及程序。分析了处理效果,并指出了今后努力的方向。

WAYS AND PROGRAMS OF MARINE GRAVITY DIGITAL DATA HANDLING

With the renewal of the development of marine gravity survey technique and gravity meter, the gravity data handling has constituted an integral part of gravity survey. This paper deals mainly with the digital data handling of Bouguer, Eotvos, normal, etc corrections and coodinate transformations of gravity data collected through the marine gravity meter Model KSS-5. All the aforementioned processes are implemented on RDS 500 and CYBER 172 computer.Moreover, the way to yield the integrated marine gravity profile and Bouguer anomoly map and the specified criteria for programming are suggested. An analysis of the processed result and some remarks on problems unsolved are made at the end of this paper.
