Processed ship-based Multibeam Sonar Data acquired during the Maurice Ewing expedition EW0114 (2001)

This data set was acquired with a ship-based Atlas Hydrosweep DS2 Multibeam Sonar system during Maurice Ewing expedition EW0114 conducted in 2001 (Chief Scientist: Dr. James Cochran). These data files are of MBSystem Compatible format and include Swath Bathymetry data and were processed at sea using the open source MB-System multibeam sonar processing software. Data were acquired as part of the project(s): The Effects of Changes in Mantle Temperature on Melt Supply and Crustal Accretion: An MCS Reflection and OBH Refraction Study of the Southeast Indian Ridge, and funding was provided by NSF grant(s): OCE99-11720.

本数据集依托船载Atlas Hydrosweep DS2多波束声呐系统采集，采集工作隶属于2001年执行的Maurice Ewing航次EW0114，该航次首席科学家为James Cochran博士。本数据集文件采用MBsystem兼容格式，包含条带测深（Swath Bathymetry）数据，且已在作业船上通过开源MB-System多波束声呐处理软件完成现场数据处理。本次数据采集作为以下研究项目的组成部分开展：《地幔温度变化对熔体供给与地壳增生的影响：东南印度洋海岭的多道地震反射（MCS Reflection）与大洋海底地震折射（OBH Refraction）研究》。本研究获得美国国家科学基金会（National Science Foundation，NSF）资助项目OCE99-11720的经费支持。
