Ship-based Trackline Geophysical Data (MGD77) acquired during the Eltanin expedition ELT47A (1971)

This data set was acquired with a ship-based Gravimeter, Echosounder Sonar, and Magnetometer during Eltanin expedition ELT47A conducted in 1971 (Chief Scientist: Dr. Kenneth L. Griffiths). These data files are of MGD77 format and include Gravity Field, Singlebeam Bathymetry, and Magnetic Field data and were processed after data collection.本数据集由船载重力仪（ship-based Gravimeter）、回声测深声呐（echosounder sonar）与磁力仪（magnetometer）采集获取，采集工作开展于1971年执行的埃尔塔宁号（Eltanin）考察航次ELT47A，该航次首席科学家为肯尼思·L·格里菲思博士。本数据集的文件采用MGD77格式，涵盖重力场数据、单波束测深数据与磁场数据，且所有数据均在采集完成后经过了处理。
