Ship-based Trackline Geophysical Data (MGD77) acquired during the Eltanin expedition ELT55 (1972)

This data set was acquired with a ship-based Magnetometer, Gravimeter, and Echosounder Sonar during Eltanin expedition ELT55 conducted in 1972 (Chief Scientist: Dr. Bruce Heezen). 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1972年执行的埃尔塔宁（Eltanin）考察航次ELT55，搭载的观测设备包括船载磁力仪（Magnetometer）、重力仪（Gravimeter）与回声测深声呐（Echosounder Sonar），本次航次的首席科学家为布鲁斯·希曾博士（Dr. Bruce Heezen）。该数据集文件采用MGD77格式，涵盖磁场数据、单波束测深（Singlebeam Bathymetry）数据及重力场数据，所有数据均在采集完成后进行了处理。
