Ship-based Trackline Geophysical Data (MGD77) acquired during the Maurice Ewing expedition EW9106 (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 EW9106 conducted in 1991 (Chief Scientist: Dr. Marcia McNutt). 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): Fracture Zone-Hot Spot Interactions Along the Marquesas Fracture Zone, and funding was provided by NSF grant(s): OCE90-11681, OCE90-12529, OCE90-12949, and OCE92-96155.本数据集采集自1991年开展的Maurice Ewing航次EW9106（首席科学家：玛西娅·麦克纳特博士），搭载的船载观测设备包括Bodenseewerk KSS-30重力仪、瓦里安（Varian Inc.）公司V75磁力仪以及阿特拉斯（Atlas）Hydrosweep DS多波束声呐系统。本批数据文件采用MGD77格式，涵盖重力场、磁场及单波束测深数据，且已在数据采集完成后完成预处理流程。本数据采集工作隶属于「马克萨斯断裂带沿线断裂带与热点相互作用」研究项目，资助方为美国国家科学基金会（NSF），对应资助编号为OCE90-11681、OCE90-12529、OCE90-12949及OCE92-96155。
