Ship-based Trackline Geophysical Data (MGD77) acquired during the Vema expedition V2807 (1970)

This data set was acquired with a ship-based Echosounder Sonar, Gravimeter, and Magnetometer during Vema expedition V2807 conducted in 1970 (Chief Scientist: Dr. Vincent Renard). These data files are of MGD77 format and include Gravity Field, Singlebeam Bathymetry, and Magnetic Field data and were processed after data collection.本数据集采集自1970年执行的维玛（Vema）科考航次V2807，搭载的观测设备包括船载回声测深声呐（Echosounder Sonar）、重力仪（Gravimeter）与磁力仪（Magnetometer），本航次首席科学家为文森特·勒纳尔（Vincent Renard）博士。本次数据集的文件格式为MGD77，涵盖重力场数据、单波束测深数据与磁场数据，且所有数据均在采集完成后进行了处理。
