Processed ship-based Multibeam Sonar Data acquired during the Maurice Ewing expedition EW9504 (1995)

This data set was acquired with a ship-based Atlas Hydrosweep DS Multibeam Sonar system during Maurice Ewing expedition EW9504 conducted in 1995 (Chief Scientist: Dr. Mitchell Lyle). These data files are of MBSystem Compatible format and include Acoustic Backscatter and Swath Bathymetry data and were processed by the GMRT Team using the open source MB-System multibeam sonar processing software as part of the GMRT Synthesis effort. These data are included in the GMRT Synthesis, version 3.0. Data were acquired as part of the project(s): Late Pleistocene Climate-Induced Fluctuations in the California Current: A Paleoceanographic Study and Ocean Drilling Project Site Survey, and funding was provided by NSF grant(s): OCE93-14512 and OCE93-15085.

本数据集系1995年Maurice Ewing探险EW9504期间，由首席科学家Dr. Mitchell Lyle领导，利用安装在船舶上的Atlas Hydrosweep DS多波束声纳系统采集而成。数据文件采用与MBSystem兼容的格式，包含声学后向散射和横扫测深数据，并由GMRT团队利用开源的MB-System多波束声纳处理软件进行加工，作为GMRT综合研究项目的一部分。这些数据已包含在GMRT综合研究版本3.0中。数据采集作为以下项目的一部分：加利福尼亚洋流受晚更新世气候影响引起的波动：一项古海洋学研究以及海洋钻探项目场地勘察，项目资金由NSF资助项目编号OCE93-14512和OCE93-15085提供。
