Ship-based Trackline Geophysical Data (MGD77) acquired during the Vema expedition V1905 (1963)

This data set was acquired with a ship-based Gravimeter, Magnetometer, and Echosounder Sonar during Vema expedition V1905 conducted in 1963 (Chief Scientist: Dr. Jim Heirtzler). These data files are of MGD77 format and include Singlebeam Bathymetry, Gravity Field, and Magnetic Field data and were processed after data collection.

本数据集由1963年执行的Vema科考航次V1905采集，本次航次首席科学家为吉姆·海茨勒（Jim Heirtzler）博士，采集时搭载了船载重力仪（Gravimeter）、磁力仪（Magnetometer）与回声测深声呐（Echosounder Sonar）。该数据集文件采用MGD77格式，涵盖单波束测深（Singlebeam Bathymetry）、重力场（Gravity Field）与磁场（Magnetic Field）三类数据，且已在数据采集完成后完成处理。
