Gridded bathymetry, 42-50 Ma NE Pacific between Molokai and Murray FZ

Bathymetry grid produced for the Ohana project located 25-30.5°N, 145.5-137.5°W in the NE Pacific. This ~500x600 km area was the site of an Ocean Bottom Seismometer array deployed Nov 2021-Feb 2023 by a team led by Gabi Laske. Donna Blackman led the bathymetry processing. Hull-mounted multibeam bathymetry data from 36 cruises available at NCEI by January 2023 were compiled, processed where necessary, and gridded at 200 m spacing. All files were first processed with MB-System using this command: mbclean -I(filelist) -F-1 -S1 -C1 -Z -B1000/6250. Further manual processing to remove outliers with mbedit was required for 22 of the cruises. Detailed processing with mbclean and mbedit was done for cruises KM2117 and SR2302, with Su Talavera-Soza and Ruei-jiun Hung contributing to the processing during the SR2302 cruise. All swath data were gridded using mbgrid. The data file is in GMT-compatible netCDF grid format.
