Near-bottom AUV multibeam bathymetry image (GeoTIFF format) from the Octopus Garden hydrothermal spring site
Near-bottom multibeam bathymetry data was collected with the MBARI Mapping AUV on 8 missions in February 2022 to cover the octopus brooding sites "Octopus Garden" and "Octocone", and to run long lines over nearby Davidson Seamount. The image file presented here is in GeoTIFF raster image 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.
