Ship-based Trackline Geophysical Data (MGD77) acquired during the Vema expedition V1906 (1963)

This data set was acquired with a ship-based Gravimeter, Magnetometer, and Echosounder Sonar during Vema expedition V1906 conducted in 1963 (Chief Scientist: Dr. William Ludwig). These data files are of MGD77 format and include Singlebeam Bathymetry, Gravity Field, and Magnetic Field data and were processed after data collection.本数据集采集于1963年执行的维玛号（Vema）V1906科考航次，搭载设备包括船载重力仪（Gravimeter）、磁力仪（Magnetometer）及回声测深声呐（Echosounder Sonar），本次航次的首席科学家为威廉·路德维希博士。本次数据集的文件采用MGD77格式，包含单波束测深数据、重力场数据及磁场数据，所有数据均在采集完成后进行了处理。
