Processed ship-based Multibeam Sonar Data from the Central America Subduction Zone acquired during the Maurice Ewing expedition EW0005 (2000)

This data set was acquired with a ship-based Atlas Hydrosweep DS Multibeam Sonar system during Maurice Ewing expedition EW0005 conducted in 2000 (Chief Scientist: Dr. Kirk McIntosh). These data files are of MBSystem format and include Acoustic Backscatter, Sidescan, 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 1. Data were acquired as part of the project(s): Structure of the Nicaragua/Costa Rica Subduction Zone: A Framework for the Subduction Factory and Seismogenic Zone Initiatives, and funding was provided by NSF grant(s): OCE99-05355 and OCE99-09859.\r

本数据集由船载Atlas Hydrosweep DS多波束声呐系统采集，采集于2000年开展的Maurice Ewing考察航次EW0005（首席科学家：Kirk McIntosh博士）。这些数据文件采用MBSystem格式，包含声学反向散射、侧扫声呐及条带测深数据，由GMRT团队使用开源MB-System多波束声呐处理软件进行处理，是GMRT综合数据集构建工作的一部分。该数据被纳入GMRT综合数据集1.0版本。数据采集是以下项目的一部分：《尼加拉瓜/哥斯达黎加俯冲带结构：俯冲工厂与发震带计划框架》，资金由美国国家科学基金会（NSF）资助项目提供，项目编号为OCE99-05355与OCE99-09859。
