Ship-based Trackline Geophysical Data (MGD77) acquired during the Eltanin expedition ELT55A (1972)

This data set was acquired with a ship-based Gravimeter, Echosounder Sonar, and Magnetometer during Eltanin expedition ELT55A conducted in 1972 (Chief Scientist: Dr. Bruce Heezen). These data files are of MGD77 format and include Magnetic Field, Gravity Field, and Singlebeam Bathymetry data and were processed after data collection.

本数据集采集于1972年开展的埃尔塔宁（Eltanin）号科考航次ELT55A，该航次搭载了船载重力仪（Gravimeter）、回声测深声呐（Echosounder Sonar）与磁力仪（Magnetometer），首席科学家为布鲁斯·希森（Bruce Heezen）博士。本次提供的数据文件采用MGD77格式，包含磁场（Magnetic Field）、重力场（Gravity Field）以及单波束测深（Singlebeam Bathymetry）数据，所有数据均在野外采集完成后进行了处理。
