Ship-based Trackline Geophysical Data (MGD77) acquired during the Vema expedition V3409 (1977)

This data set was acquired with a ship-based Echosounder Sonar, Gravimeter, and Magnetometer during Vema expedition V3409 conducted in 1977 (Chief Scientist: Dr. Roger Anderson). These data files are of MGD77 format and include Magnetic Field, Singlebeam Bathymetry, and Gravity Field data and were processed after data collection.

本数据集依托1977年执行的Vema考察航次V3409获取，该航次首席科学家为罗杰·安德森（Roger Anderson）博士。数据采集过程中使用了船载回声测深声呐（Echosounder Sonar）、重力仪（Gravimeter）与磁力仪（Magnetometer）。本数据集的文件采用MGD77格式，涵盖磁场数据、单波束测深（Singlebeam Bathymetry）数据与重力场数据，且所有数据均在采集完成后经过处理。
