Ship-based Trackline Geophysical Data (MGD77) acquired during the Discoverer expedition DI-91-01 (1991)

This data set was acquired with a ship-based SeaBeam Multibeam Sonar system during Discoverer expedition DI-91-01 conducted in 1991 (Chief Scientist: Dr. Robert Embley). These data files are of MGD77 format and include Singlebeam Bathymetry data and were processed after data collection. Data were acquired as part of the project(s): Deep Tow Magnetometer survey, Cleft and Vance segments, Juan de Fuca Ridge.

本数据集系1991年“Discoverer”号考察航次DI-91-01期间，借助船载SeaBeam多波束声呐系统（SeaBeam Multibeam Sonar system）采集所得，本次航次首席科学家为罗伯特·恩布利（Robert Embley）博士。本数据集文件采用MGD77格式，包含单波束测深数据（Singlebeam Bathymetry data），且已在数据采集完成后完成处理。本次数据采集工作隶属于以下项目：深拖磁法测量（Deep Tow Magnetometer survey），以及胡安·德富卡洋脊（Juan de Fuca Ridge）克莱夫段与万斯段的相关科考任务。
