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2011年进行的亚特兰蒂斯探险AT18-08期间，搭载康斯伯格EM122多波束测深系统所采集。数据文件采用MBSystem格式，包含侧扫声纳、条带地形测量和声学后向散射数据，并由GMRT团队利用开源的MB-System多波束测深处理软件进行加工，作为GMRT综合研究项目的一部分。这些数据包含在GMRT综合研究版本2.3中。数据采集属于以下项目的一部分：2011年NeMO项目——阿克塞尔火山和恩德维尤段，协同研究：监测阿克塞尔火山的膨胀，协同研究：热水喷口拟阿丝虫的热生物学，恩德维尤ISS站点的电阻率探头部署，以及电阻率仪器的必要升级，资金支持来源于美国国家科学基金会（NSF）的以下资助项目：OCE06-23383、OCE06-23554、OCE07-25605、OCE07-26093、OCE07-51868和OCE08-19004。
