Ship-based Trackline Geophysical Data (MGD77) acquired during the Vema expedition V3211 (1975)

This data set was acquired with a ship-based Gravimeter, Echosounder Sonar, and Magnetometer during Vema expedition V3211 conducted in 1975 (Chief Scientist: Dr. Dennis Hayes). These data files are of MGD77 format and include Magnetic Field, Gravity Field, and Singlebeam Bathymetry data and were processed after data collection.

本数据集采集自1975年执行的维玛号（Vema）科考航次V3211，搭载的观测设备包括船载重力仪（Gravimeter）、测深声纳（Echosounder Sonar）与磁力仪（Magnetometer），本次航次首席科学家为丹尼斯·海斯博士（Dr. Dennis Hayes）。本次数据集文件采用MGD77格式，涵盖磁场、重力场与单波束测深数据，且所有数据均在采集完成后经过处理。
