Ship-based Trackline Geophysical Data (MGD77) acquired during the Vema expedition V2817 (1971)

This data set was acquired with a ship-based Echosounder Sonar, Gravimeter, and Magnetometer during Vema expedition V2817 conducted in 1971 (Chief Scientist: Dr. Robert Leyden). These data files are of MGD77 format and include Magnetic Field, Gravity Field, and Singlebeam Bathymetry data and were processed after data collection.

本数据集由船载回声测深声呐、重力仪及磁力仪搭载采集，于1971年执行的Vema科考航次V2817期间获取（首席科学家：Robert Leyden博士）。该批数据文件采用MGD77格式存储，包含磁场、重力场与单波束测深数据，且已在数据采集完成后进行处理。
