Near-bottom AUV multibeam bathymetry grid (ESRI ASCII format) from the Octopus Garden hydrothermal spring site

Near-bottom multibeam bathymetry data were collected with the MBARI Mapping AUV on 8 missions in February 2022 to cover the octopus brooding sites "Octopus Garden" and "Octocone". The grid file presented here is in ESRI ASCII format and the projection is UTM zone 10N. The AUV was operated at 50-m altitude for 1-m lateral resolution data. Position and attitude were provided by a Kearfott SeaDevil Inertial Navigation System (INS) integrated with a 1200 kHz Teledyne RD Instruments Doppler velocity log (DVL) and a Paroscientific pressure sensor, and the navigation has been adjusted and tied to a GPS-navigated regional bathymetry grid using the MB-System mbnavadjust program. Funding was provided by a grant from the David and Lucile Packard Foundation to MBARI.
