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.
