Ship-based Trackline Geophysical Data (MGD77) acquired during the Vema expedition V2204 (1966)

This data set was acquired with a ship-based Magnetometer, Echosounder Sonar, and Gravimeter during Vema expedition V2204 conducted in 1966 (Chief Scientist: Dr. Xavier Le Pichon). These data files are of MGD77 format and include Magnetic Field, Gravity Field, and Singlebeam Bathymetry data and were processed after data collection.本数据集采集于1966年开展的维玛号（Vema）科考航次V2204，搭载设备包括船载磁力仪（Magnetometer）、回声测深声呐（Echosounder Sonar）与重力仪（Gravimeter），该航次首席科学家为泽维尔·勒皮雄（Xavier Le Pichon）博士。本数据集文件采用MGD77格式，包含磁场（Magnetic Field）、重力场（Gravity Field）与单波束测深数据（Singlebeam Bathymetry data），且已在数据采集完成后完成处理。
