Ship-based Trackline Geophysical Data (MGD77) acquired during the Maurice Ewing expedition EW0204 (2002)

This data set was acquired with a ship-based BellAerospace BGM-3 Gravimeter and Atlas Hydrosweep DS2 Multibeam Sonar system during Maurice Ewing expedition EW0204 conducted in 2002 (Chief Scientist: Dr. Dale Chayes). These data files are of MGD77 format and include Gravity Field and Singlebeam Bathymetry data and were processed after data collection. Data were acquired while the Maurice Ewing was in transit.本数据集由2002年执行的莫里斯·尤因（Maurice Ewing）号航次EW0204（首席科学家：戴尔·蔡斯（Dale Chayes）博士）搭载船载BellAerospace BGM-3重力仪（Gravimeter）与Atlas Hydrosweep DS2多波束声呐（Multibeam Sonar）系统采集获得。该数据集文件采用MGD77格式，包含重力场数据与单波束测深（Singlebeam Bathymetry）数据，且已于数据采集完成后完成处理。本次数据采集工作全程在莫里斯·尤因号科考船的航行途中开展。
