Ship-based Trackline Geophysical Data (MGD77) acquired during the Maurice Ewing expedition EW9901 (1999)

This data set was acquired with a ship-based Atlas Hydrosweep DS Multibeam Sonar system, Geometrics G-886 Magnetometer, and BellAerospace BGM-3 Gravimeter during Maurice Ewing expedition EW9901 conducted in 1999 (Chief Scientist: Dr. Deborah Smith). 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): Long Term Monitoring of Seismicity at the Mid-Atlantic Ridge Using Autonomous Underwater Hydrophones, and funding was provided by NSF grant(s): OCE98-11575 and OCE98-12237.

本数据集是在1999年开展的Maurice Ewing航次EW9901（首席科学家：Deborah Smith博士）期间，通过船载Atlas Hydrosweep DS多波束声呐系统、Geometrics G-886磁力仪及BellAerospace BGM-3重力仪采集获取的。该数据集文件格式为MGD77，包含单波束测深数据、重力场数据与磁场数据，且所有数据均在采集完成后进行了处理。本次数据采集隶属于“利用自主水下水听器长期监测大西洋中脊地震活动”项目，项目资助方为美国国家科学基金会（NSF），资助编号为OCE98-11575与OCE98-12237。
