Ship-based Trackline Geophysical Data (MGD77) acquired during the Eltanin expedition ELT39 (1969)

This data set was acquired with a ship-based Magnetometer, Echosounder Sonar, and Gravimeter during Eltanin expedition ELT39 conducted in 1969 (Chief Scientist: Dr. Merle R. Dawson). These data files are of MGD77 format and include Gravity Field, Magnetic Field, and Singlebeam Bathymetry data and were processed after data collection.

本数据集采集自1969年执行的埃尔塔宁（Eltanin）考察航次ELT39，依托船载磁力仪（Magnetometer）、回声测深声呐（Echosounder Sonar）与重力仪（Gravimeter）完成数据采集工作，该航次首席科学家为默尔·R·道森博士。本次数据集文件采用MGD77格式，涵盖重力场、磁场及单波束测深数据，并于数据采集完成后进行了处理。
