Ship-based Trackline Geophysical Data (MGD77) acquired during the Vema expedition V1805 (1962)

This data set was acquired with a ship-based Magnetometer, Echosounder Sonar, and Gravimeter during Vema expedition V1805 conducted in 1962 (Chief Scientist: Dr. Maurice Ewing). These data files are of MGD77 format and include Singlebeam Bathymetry, Magnetic Field, and Gravity Field data and were processed after data collection.本数据集采集于1962年开展的Vema探险队V1805航次，本次航次首席科学家为莫里斯·尤因博士，观测所用设备包括船载磁力计（Magnetometer）、回声测深声呐（Echosounder Sonar）与重力仪（Gravimeter）。该数据集文件采用MGD77格式，包含单波束测深数据、磁场数据与重力场数据，且已在数据采集完成后完成处理。
