Ship-based Trackline Geophysical Data (MGD77) acquired during the Maurice Ewing expedition EW9001 (1990)

This data set was acquired with a ship-based Atlas Hydrosweep DS Multibeam Sonar system and Varian Inc. V75 Magnetometer during Maurice Ewing expedition EW9001 conducted in 1990 (Chief Scientist: Dr. John Diebold). These data files are of MGD77 format and include Singlebeam Bathymetry and Magnetic Field data and were processed after data collection. Data were acquired while the Maurice Ewing was in transit, and funding was provided by NSF grant(s): OCE90-01169.

本数据集采集于1990年开展的莫里斯·尤因（Maurice Ewing）号航次EW9001，使用船载Atlas Hydrosweep DS多波束声呐系统（Atlas Hydrosweep DS Multibeam Sonar）与瓦里安公司（Varian Inc.）V75型磁力仪完成采集，本航次首席科学家为约翰·迪博尔德博士（Dr. John Diebold）。本次数据文件采用MGD77格式，包含单波束测深数据与磁场数据，且已在数据采集完成后进行处理。数据采集工作在莫里斯·尤因号航行途中开展，资助方为美国国家科学基金会（National Science Foundation，简称NSF）项目编号OCE90-01169的科研拨款。
