Processed ship-based Multibeam Sonar Data (version 2) acquired at the Juan de Fuca Spreading Center during the Atlantis expedition AT18-08 (2011)

This data set was acquired with a ship-based Kongsberg EM122 Multibeam Sonar system during Atlantis expedition AT18-08 conducted in 2011 (Chief Scientist: Dr. William Chadwick). These data files are of MBSystem format and include Sidescan, Swath Bathymetry, and Acoustic Backscatter 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 2.3. Data were acquired as part of the project(s): NeMO 2011 - Axial Seamount and Endeavour Segment, Collaborative Research: Monitoring inflation at Axial Seamount, Collaborative Research: Thermal biology of hydrothermal vent paralvinellid worms, Resistivity Probe Deployments at the Endeavour ISS, and Essential upgrades to resistivity instruments, and funding was provided by NSF grant(s): OCE06-23383, OCE06-23554, OCE07-25605, OCE07-26093, OCE07-51868, and OCE08-19004.

本数据集由船载康士伯（Kongsberg）EM122多波束声呐系统采集自2011年执行的亚特兰蒂斯号（Atlantis）科考航次AT18-08，本航次首席科学家为威廉·查德威克（William Chadwick）博士。本次数据文件采用MBsystem格式存储，包含侧扫声呐、条带测深与声学背散射数据，由GMRT团队依托开源MB-System多波束声呐处理软件，作为GMRT综合项目的一部分完成处理。本数据集隶属于GMRT综合项目2.3版本。数据采集隶属于以下多项研究项目：NeMO 2011——轴状海山与恩达佛段协作研究、轴状海山隆升监测协作研究、热液喷口副沙蚕科蠕虫热生物学研究、恩达佛ISS区电阻率探针部署项目，以及电阻率仪器必要升级项目。本项目由美国国家科学基金会（National Science Foundation, NSF）提供资助，资助编号包括：OCE06-23383、OCE06-23554、OCE07-25605、OCE07-26093、OCE07-51868及OCE08-19004。
