Ohana_Laske Bathymetry
Gridded multibeam swath bathymetry data 37-40 Ma NE Pacific 31°N, 133°W
Bathymetry grid produced as an add-on to the Ohana project. This grid covers 30.5-32.5°N, 134.5-132 °W in the NE Pacific which is to the east of the main Ohana project area. This smaller eastern area was mapped during R/V Sally Ride cruise SR2302 following Ocean Bottom Seismometer array recovery in February 2023 by a team led by Gabi Laske. Donna Blackman led the bathymetry processing and Su Talavera-Soza and Ruei-jiun Hung contributed. Detailed processing for cruise SR2302 was done manually with MB-System mbedit. Hull-mounted multibeam bathymetry data from 5 additional cruises available at NCEI as of January 2023 were compiled with the processed SR2302 multibeam data. All data were gridded at 200 m using mbgrid. The data file is in GMT-compatible netCDF grid format.
