Title:
Processed bathymetric data (netCDF grid) from 9°50'N, East Pacific Rise, acquired in 2018, 2019 and 2021 during AUV Sentry near-bottom dives
Abstract:
Bathymetric data were collected during a total of 19 AUV Sentry dives conducted from R/V Atlantis and R/V Roger Revelle during 2018 Atlantis cruise AT42-06 (two dives); 2019 Atlantis cruise AT42-21 (ten dives); and, 2021 Revelle cruise RR2102 (seven dives). Track lines were spaced 170 m apart, with Sentry about 65 m above bottom, collecting multibeam data using a 400 kHz Reson 7125 system in 2018, and a 400 kHz Kongsberg EM2040 system in 2019 and 2021. Sentry navigation was obtained using a 300 kHz Teledyne Doppler velocity log (DVL) and a Sonardyne AvTrak2 ultra-short baseline (USBL) acoustic positioning system, combined with an iXblue Phins inertial navigation system (INS), and a Paroscientific 8B7000-I Digiquartz depth sensor. Sonar data from all 19 dives were processed together using the open-source MB-System software, and were gridded at 1 m × 1 m node resolution using a beam footprint calculated with the angular beam widths and weighted by local slope. The grid file is in GMT-compatible netCDF format, in un-projected geographic coordinates.
