ODEMAR shipboard Pourquoi Pas? multibeam bathymetry

Multibeam bathymetry data, gridded at 40m, acquired around the 13°20'N and 13°30'N oceanic detachments along the Mid-Atlantic Ridge. Bathymetric data was acquired by the PourQUoi Pas? multibeam system (RESON 7150).

Data is provided as a grid in GRD format (GMT NETCDF).
