中国科学院南海海洋研究所--SA06、07区块地质地球物理补充调查-磁力测量数据ZN4（走航式测量-MAPM-93）-19980518-19980528

SA06、07区块地质地球物理补充调查重力测量数据集于1998年5月海上调查获取，主要覆盖区域为南海东南部海域，测线按1:100万要求布置，数据主要包含数据点的经纬度和重力值信息。仪器使用KSS30海洋重力仪，GPS无差分定位精度可达 15~25m，实时差分定位精度为1~3m。

The gravity survey dataset for the supplementary geological and geophysical surveys of Blocks SA06 and SA07 was acquired during marine surveys conducted in May 1998. Its primary coverage area is the southeastern waters of the South China Sea, and the survey lines were deployed in accordance with the 1:1,000,000 scale specification. The dataset mainly contains the latitude, longitude and gravity value information of each survey point. The KSS30 marine gravimeter was utilized as the measuring instrument, with the GPS non-differential positioning accuracy ranging from 15 m to 25 m and the real-time differential positioning accuracy between 1 m and 3 m.
