Dataset identification

Title of datasetODEMAR shipboard Pourquoi Pas? multibeam bathymetry
Narrative summary of datasetMultibeam 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). grdinfo of the file: + ODEMAR_Shipboard_Bathymetry_40m.grd: Title: Bathy_40m.grd + ODEMAR_Shipboard_Bathymetry_40m.grd: Command: File written by MATLAB function grdwrite2.m + ODEMAR_Shipboard_Bathymetry_40m.grd: Remark: Created 22-Nov-2014 16:35:13 + ODEMAR_Shipboard_Bathymetry_40m.grd: Gridline node registration used [Cartesian grid] + ODEMAR_Shipboard_Bathymetry_40m.grd: Grid file format: nf = GMT netCDF format (32-bit float), COARDS, CF-1.5 + ODEMAR_Shipboard_Bathymetry_40m.grd: x_min: -45.14293893 x_max: -44.77177893 x_inc: 0.00036 name: x nx: 1032 + ODEMAR_Shipboard_Bathymetry_40m.grd: y_min: 13.20017553 y_max: 13.62389553 y_inc: 0.00036 name: y ny: 1178 + ODEMAR_Shipboard_Bathymetry_40m.grd: z_min: -4498.29248047 z_max: -1935.33117676 name: z + ODEMAR_Shipboard_Bathymetry_40m.grd: scale_factor: 1 add_offset: 0 + ODEMAR_Shipboard_Bathymetry_40m.grd: format: classic
