Sentry AUV near-bottom processed swath bathymetry data (*p.mb88 format), Shinkai Deep and FeMO hydrothermal vent sites (FK140625, 2014) at Loihi Seamount (Hawaii)

This processed swath bathymetry data set was collected at the Loihi Seamount Shinkai Deep and FeMO hydrothermal vent sites with a Reson SeaBat 7125 multibeam sonar system during Sentry AUV dives 265-270. The data files are in MB-System-compatible format (mbio format 88) and contain processed swath bathymetry and acoustic backscatter data. The dives were conducted during the 2014 R/V Falkor cruise FK140625 (chief scientist Brian Glazer, University of Hawaii) as part of the projects called Characterization of Microbial Transformations in Basement Fluids, from Genes to Geochemical Cycling; and, Redox dynamics resulting from chemical and physical fluxes in surficial permeable sediments. Funding was provided with NSF awards OCE10-31947 and OCE10-61827 and by the Schmidt Ocean Institute. The AUV was operated by WHOI:NDSF. The data files were reprocessed in 2016 by Jennifer Paduan (MBARI) with funding provided by a grant from the David and Lucile Packard Foundation to MBARI.

本处理完成的条带测深（swath bathymetry）数据集采集自罗希海底山（Loihi Seamount）的新深海槽（Shinkai Deep）与FeMO热液喷口位点，数据采集搭载Reson SeaBat 7125型多波束声呐系统，于“森特里”号自主水下航行器（Autonomous Underwater Vehicle，简称AUV）的265至270次下潜任务中完成。该数据集文件采用MB-System兼容格式（mbio格式88），包含已处理的条带测深数据与声学背散射数据。本次下潜任务执行于2014年“福尔库号”研究船（R/V Falkor）FK140625航次，首席科学家为夏威夷大学的Brian Glazer，相关工作隶属于两项研究项目：《基底流体中微生物转化的表征：从基因到地球化学循环》与《表层渗透性沉积物中化学与物理通量驱动的氧化还原动力学》。本项目的资金支持来自美国国家科学基金会（National Science Foundation，简称NSF）的OCE10-31947与OCE10-61827两项资助，以及施密特海洋研究所（Schmidt Ocean Institute）。该自主水下航行器由伍兹霍尔海洋研究所国家深潜设施（WHOI:NDSF）运维。数据集文件于2016年由Jennifer Paduan（蒙特雷湾水族馆研究所（Monterey Bay Aquarium Research Institute，简称MBARI））完成重新处理，相关经费来自大卫与露西尔·帕卡德基金会授予蒙特雷湾水族馆研究所的专项拨款。
