- Use limitation
- The Single Beam bathymetry of the Italian side of the Adriatic compiled by ISMAR can be applied in oceanographic numerical model as uniform resolution GRID. The main advantages in using this kind of bathymetry, obtained from manual interpretation and contouring, is the generation of consistent model taking into account the actual sea floor morphology and its relation to key geological features. The main limitation come from the heterogeneity of the bathymetric data in terms of distribution and quality, and the possible errors generated during the interpolation procedures applied to derive an homogeneous resolution GRID.

Description of data processing :
The bathymetric data were migrated in a GIS Database and plotted as water depth points on different maps, at different scale depending on the soundings density, dividing the Adriatic in subset areas from north to south. Following an interpretative approach, based also on the interpretation of geological sub-seafloor features using CHIRP-sonar profiles, the bathymetric contours were manually drawn and digitised as vector data in a GIS, with variable space according to water depth range (contour every 1 m from 5 to 150 m and every 20 m from 150 m to 1200 m). The contours were used to generate a uniform GRID (200 m) using a kriging algorithm with variable resolution depending on the soundings density.

Description of processed data sources :
Single Beam sonar data were collected using an hull-mounted Echo sounder (Atlas Deso25 operating at frequencies of 12, 100, 33 and 210KHz) along about 17.830 km of seismic profiles during 22 cruises performed by ISMAR from 1991 to 2005 on board R/V Urania in the Italian side of the Adriatic Sea. The echo sounding profiles are unevenly distributed and the seafloor coverage is within the range of one sounding every 20-40 m, along track. The Echo sounder Atlas Deso25 was merged with the navigation system NAV PRO from Communication Technology and with DGPS positioning system with metrical accuracy.
