Ship-based Trackline Geophysical Data (MGD77) acquired during the Vema expedition V1615 (1960)

This data set was acquired with a ship-based Echosounder Sonar and Magnetometer during Vema expedition V1615 conducted in 1960 (Chief Scientist: Dr. Charles Drake). These data files are of MGD77 format and include Magnetic Field and Singlebeam Bathymetry data and were processed after data collection.本数据集由船载回声测深声呐（Echosounder Sonar）与磁力仪（Magnetometer）采集于1960年开展的维玛号（Vema）考察航次V1615（首席科学家：查尔斯·德雷克博士）。所用数据文件均采用MGD77格式，包含磁场数据与单波束测深数据（Singlebeam Bathymetry），且已在数据采集完成后完成处理。
