Ship-based Trackline Geophysical Data (MGD77) acquired during the Vema expedition V3214 (1975)

This data set was acquired with a ship-based Magnetometer, Gravimeter, and Echosounder Sonar during Vema expedition V3214 conducted in 1975 (Chief Scientist: Dr. Roger Larson). These data files are of MGD77 format and include Magnetic Field, Singlebeam Bathymetry, and Gravity Field data and were processed after data collection.本数据集采集于1975年开展的维玛号（Vema）科考航次V3214，该航次搭载船载磁力仪(Magnetometer)、重力仪(Gravimeter)与回声测深声呐(Echosounder Sonar)完成数据获取，本次航次的首席科学家为罗杰·拉森博士。本数据集的所有文件均采用MGD77格式，包含磁场数据、单波束测深(Singlebeam Bathymetry)数据与重力场数据，且所有数据均在采集完成后经过了处理。
