Dataset identification

Title of datasetMultibeam echo sounders (MBES) bathymetry from Ormonde
Narrative summary of datasetDigital Elevation Model (DEM) of Ormonde from MEDWAVES cruise bathymetry data. ATLAS project
Summary of processing methodologyUsed MBES was a Hydrosweep DS-3 model from ATLAS. Beam width is 1º along tarck by 1º across track. Position records from GPS and vessel attitude is controlled by a POS MV unit from Applanix. Sound refraction is corrected by real time measurements of the sound velocity at the transducer depth in addition to sound velocity profiles of the water column gathered from different CTD casts taken before and after each survey. The software for procesing bathimetric data was CARIS 10. Resulting grid has been resampled to 1/8 minute grid georreferenced to mercator WGS84 in decimal degrees.
