Ship-based Trackline Geophysical Data (MGD77) acquired during the Vema expedition V3617 (1980)

This data set was acquired with a ship-based Echosounder Sonar, Magnetometer, and Gravimeter during Vema expedition V3617 conducted in 1980 (Chief Scientist: Dr. James Cochran). These data files are of MGD77 format and include Singlebeam Bathymetry, Magnetic Field, and Gravity Field data and were processed after data collection.本数据集是在1980年执行的Vema号科考航次V3617期间，由船载回声测深声呐、磁力仪与重力仪采集得到，本次航次的首席科学家为詹姆斯·科克伦（James Cochran）博士。该数据集文件采用MGD77格式，包含单波束测深数据、磁场数据与重力场数据，且所有数据均在采集完成后进行了处理。
