Ship-based Trackline Geophysical Data (MGD77) acquired during the Maurice Ewing expedition EW9704 (1997)

This data set was acquired with a ship-based BellAerospace BGM-3 Gravimeter, Atlas Hydrosweep DS Multibeam Sonar system, and Geometrics G-886 Magnetometer during Maurice Ewing expedition EW9704 conducted in 1997 (Chief Scientist: Dr. John Collins). These data files are of MGD77 format and include Singlebeam Bathymetry, Gravity Field, and Magnetic Field data and were processed after data collection. Data were acquired as part of the project(s): Shallow Crustal Structure at a Slow Spreading Ridge, and funding was provided by NSF grant(s): OCE96-33114.

本数据集采集自1997年执行的Maurice Ewing航次EW9704（首席科学家：John Collins博士），搭载船载BellAerospace BGM-3重力仪、Atlas Hydrosweep DS多波束声呐系统及Geometrics G-886磁力仪完成数据获取。本次采集的数据文件采用MGD77格式，包含单波束测深、重力场与磁场数据，且已在数据采集完成后进行了处理。本数据集隶属于“慢扩张脊浅部地壳结构”研究项目，资助经费由美国国家科学基金会（National Science Foundation, NSF）项目编号OCE96-33114提供。
