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.

本数据集由船载贝尔航空航天（BellAerospace）BGM-3重力仪（Gravimeter）、Atlas Hydrosweep DS多波束声呐系统以及Geometrics G-886磁力仪（Magnetometer）采集获取，采集工作于1997年执行的莫里斯·尤因（Maurice Ewing）航次EW9704期间完成，该航次首席科学家为约翰·柯林斯（John Collins）博士。本数据集文件格式为MGD77，包含单波束测深（Singlebeam Bathymetry）数据、重力场（Gravity Field）数据与磁场（Magnetic Field）数据，所有数据均在采集完成后经过处理。本次数据采集隶属于“慢扩张脊浅部地壳结构”研究项目，资助方为美国国家科学基金会（NSF）的OCE96-33114号资助项目。
