Ship-based Trackline Geophysical Data (MGD77) acquired during the Vema expedition V1806 (1962)

This data set was acquired with a ship-based Gravimeter, Echosounder Sonar, and Magnetometer during Vema expedition V1806 conducted in 1962 (Chief Scientist: Dr. Maurice Ewing). These data files are of MGD77 format and include Gravity Field, Singlebeam Bathymetry, and Magnetic Field data and were processed after data collection.本数据集由1962年执行的Vema科考航次V1806（首席科学家：莫里斯·尤因博士）搭载船载重力仪（Gravimeter）、回声测深声呐（Echosounder Sonar）与磁力仪（Magnetometer）采集获得。该数据集文件采用MGD77格式，包含重力场（Gravity Field）、单波束测深（Singlebeam Bathymetry）及磁场（Magnetic Field）数据，且已在数据采集完成后进行了后期处理。
