Ship-based Trackline Geophysical Data (MGD77) acquired during the Vema expedition V1819 (1962)

This data set was acquired with a ship-based Echosounder Sonar, Gravimeter, and Magnetometer during Vema expedition V1819 conducted in 1962 (Chief Scientist: Dr. Charles Drake). These data files are of MGD77 format and include Magnetic Field, Singlebeam Bathymetry, and Gravity Field data and were processed after data collection.本数据集采集自1962年执行的Vema航次V1819，本次航次的首席科学家为Charles Drake博士，数据采集使用了船载回声测深声呐（Echosounder Sonar）、重力仪（Gravimeter）与磁力仪（Magnetometer）。该批数据文件采用MGD77格式存储，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进行了处理。
