Ship-based Trackline Geophysical Data (MGD77) acquired during the Eltanin expedition ELT54B (1972)

This data set was acquired with a ship-based Magnetometer, Gravimeter, and Echosounder Sonar during Eltanin expedition ELT54B conducted in 1972 (Chief Scientist: Dr. Rudi G. Markl). These data files are of MGD77 format and include Gravity Field, Magnetic Field, and Singlebeam Bathymetry data and were processed after data collection.本数据集采用船载磁力仪（ship-based Magnetometer）、重力仪（Gravimeter）及回声测深声呐（Echosounder Sonar），于1972年开展的埃尔塔宁（Eltanin）科考航次ELT54B期间采集获得，本次航次的首席科学家为鲁迪·G·马克尔（Rudi G. Markl）博士。该数据集文件采用MGD77格式，涵盖重力场（Gravity Field）、磁场（Magnetic Field）及单波束测深（Singlebeam Bathymetry）数据，且已在数据采集后完成处理。
