Ship-based Trackline Geophysical Data (MGD77) acquired during the Vema expedition V3208 (1975)

This data set was acquired with a ship-based Gravimeter, Echosounder Sonar, and Magnetometer during Vema expedition V3208 conducted in 1975 (Chief Scientist: Dr. Robert Leyden). These data files are of MGD77 format and include Gravity Field, Magnetic Field, and Singlebeam Bathymetry data and were processed after data collection.本数据集采集于1975年开展的Vema航次V3208（首席科学家：Robert Leyden博士），搭载的观测设备包括船载重力仪（Gravimeter）、回声测深声呐（Echosounder Sonar）与磁力仪（Magnetometer）。本次数据文件采用MGD77格式，涵盖重力场（Gravity Field）数据、磁场（Magnetic Field）数据与单波束测深（Singlebeam Bathymetry）数据，且所有数据均在采集完成后进行了处理。
