Global Gridded Bathymetric Data: Synthetic Bathymetric 
Location: 
Profiling System (SYNBAPS-IT) 
All ocean areas except the Artic Ocean 
Description of Data: The gridded data base was compiled by the Naval Ocean 
Research and Development Activity (NORDA) and the Naval Oceanographic Office. 
It was interpolated with digitization of bathymetric maps available up to 
1981. This enlarged global data base is called SYNBAPS-II and contains some 
7.8 million depth values on 5-min by 5-min latitude/longitude grids.
