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.本数据集由船载回声测深声呐（Echosounder Sonar）、重力仪（Gravimeter）与磁力仪（Magnetometer）采集获取，采集于1962年执行的维玛（Vema）考察航次V1819，该航次首席科学家为查尔斯·德雷克博士。本次数据集采用MGD77格式存储，涵盖磁场数据、单波束测深（Singlebeam Bathymetry）数据与重力场数据，且已在数据采集完成后完成处理。
