Ship-based Trackline Geophysical Data (MGD77) from the East Pacific Rise acquired during the Maurice Ewing expedition EW9102 (1991)

This data set was acquired with a ship-based Bodenseewerk KSS-30 Gravimeter, Varian Inc. V75 Magnetometer, and Atlas Hydrosweep DS Multibeam Sonar system during Maurice Ewing expedition EW9102 conducted in 1991 (Chief Scientist: Dr. Robert Detrick). These data files are of MGD77 format and include Singlebeam Bathymetry, Magnetic Field, and Gravity Field data and were processed after data collection. Data were acquired as part of the project(s): Two-Ship Multichannel Seismic Investigation of the East Pacific Rise South of the Garret Fracture Zone, and funding was provided by NSF grant(s): OCE90-12596, OCE90-12707, OCE90-12781, OCE91-02899, and OCE92-96017.

本数据集由船载Bodenseewerk KSS-30重力仪（Bodenseewerk KSS-30 Gravimeter）、瓦里安公司（Varian Inc.）V75磁力仪（V75 Magnetometer）以及Atlas Hydrosweep DS多波束测深声呐系统（Atlas Hydrosweep DS Multibeam Sonar system）采集，采集工作依托1991年执行的莫里斯·尤因号科考航次EW9102完成，本次航次的首席科学家为罗伯特·德特里克博士（Dr. Robert Detrick）。本次采集的数据文件采用MGD77格式（MGD77 format），涵盖单波束测深（Singlebeam Bathymetry）、磁场（Magnetic Field）与重力场（Gravity Field）三类数据，且所有数据均在野外采集完成后进行了后期处理。本数据为“加勒特断裂带以南东太平洋海隆双船多通道地震调查（Two-Ship Multichannel Seismic Investigation of the East Pacific Rise South of the Garret Fracture Zone）”项目的组成部分，研究工作获得了美国国家科学基金会（National Science Foundation，NSF）的多项拨款支持，拨款编号依次为OCE90-12596、OCE90-12707、OCE90-12781、OCE91-02899以及OCE92-96017。
