Ship-based Trackline Geophysical Data (MGD77) acquired during the Eltanin expedition ELT41A (1970)

This data set was acquired with a ship-based Magnetometer, Echosounder Sonar, and Gravimeter during Eltanin expedition ELT41A conducted in 1970 (Chief Scientist: Dr. Frank E. Snodgrass). 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1970年执行的埃尔塔宁（Eltanin）考察航次ELT41A，搭载的观测设备包括船载磁力仪（Magnetometer）、回声测深声呐（Echosounder Sonar）与重力仪（Gravimeter），本航次首席科学家为弗兰克·E·斯努德格拉斯博士。本数据集文件采用MGD77格式，涵盖磁场数据、单波束测深（Singlebeam Bathymetry）数据与重力场数据，所有数据均在数据采集完成后进行了处理。
