Ship-based Trackline Geophysical Data (MGD77) acquired during the Vema expedition V3406 (1977)

This data set was acquired with a ship-based Magnetometer, Gravimeter, and Echosounder Sonar during Vema expedition V3406 conducted in 1977 (Chief Scientist: Dr. John Damuth). These data files are of MGD77 format and include Magnetic Field, Singlebeam Bathymetry, and Gravity Field data and were processed after data collection.

本数据集采集于1977年开展的V3406号Vema科考航次，搭载船载磁力仪（Magnetometer）、重力仪（Gravimeter）与回声测深声呐（Echosounder Sonar）完成观测，本次航次的首席科学家为John Damuth博士。本次提供的数据文件采用MGD77格式，包含磁场数据、单波束测深数据与重力场数据，且所有数据均在采集完成后完成了处理。
