Ship-based Trackline Geophysical Data (MGD77) acquired during the Maurice Ewing expedition EW9309 (1993)

This data set was acquired with a ship-based Bodenseewerk KSS-30 Gravimeter, Atlas Hydrosweep DS Multibeam Sonar system, and Varian Inc. V75 Magnetometer during Maurice Ewing expedition EW9309 conducted in 1993 (Chief Scientist: Dr. Jean-Guy Schilling). These data files are of MGD77 format and include Gravity Field, Magnetic Field, and Singlebeam Bathymetry data and were processed after data collection. Data were acquired as part of the project(s): Rock Dredging and Geochemistry of the Mid-Atlantic Ridge from 41 Degrees South to 51 Degrees South, and funding was provided by NSF grant(s): OCE90-11741.

本数据集获取自1993年开展的莫里斯·尤因（Maurice Ewing）航次EW9309，本次航次首席科学家为让-吉·席林（Jean-Guy Schilling）博士，搭载的船载观测设备包括Bodenseewerk KSS-30型重力仪（Bodenseewerk KSS-30 Gravimeter）、Atlas Hydrosweep DS多波束声呐系统（Atlas Hydrosweep DS Multibeam Sonar system）以及瓦里安公司（Varian Inc.）V75型磁力仪（V75 Magnetometer）。本数据集文件采用MGD77格式（MGD77 format），涵盖重力场（Gravity Field）、磁场（Magnetic Field）与单波束测深（Singlebeam Bathymetry）数据，所有数据均在野外采集完成后进行了预处理。本数据集隶属于"南纬41°至51°大西洋中脊岩石疏浚与地球化学研究"项目，该项目由美国国家科学基金会（National Science Foundation, NSF）项目OCE90-11741资助。
