This data set was acquired with a ship-based Atlas Hydrosweep DS2 Multibeam Sonar system during Maurice Ewing expedition EW0401 conducted in 2004 (Chief Scientist: Dr. Michael Rawson). These data files are of MGD77 format and include Singlebeam Bathymetry data and were processed after data collection. Data were acquired while the Maurice Ewing was in transit.本数据集搭载船载Atlas Hydrosweep DS2多波束声呐系统（Atlas Hydrosweep DS2 Multibeam Sonar system），于2004年执行的莫里斯·尤因号（Maurice Ewing）EW0401科考航次中采集所得，该航次首席科学家为Michael Rawson博士。本次数据文件采用MGD77格式，包含单波束测深数据，且已在数据采集完成后完成后处理。数据采集工作于莫里斯·尤因号航行途中开展。
