A digital gazetteer of the names of features on the seafloor
The GEBCO Sub-Committee on Undersea Feature Names (SCUFN) maintains and makes available a digital gazetteer of the names, generic feature type and geographic position of features on the seafloor.
The gazetteer is available to view and download via a web map application, hosted by the International Hydrographic Organization Data Centre for Digital Bathymetry (IHO DCDB) co-located with the US National Centers for Environmental Information (NCEI).
The data are available in a number of formats including spreadsheet and shapefile.
Name proposals can be submitted to SCUFN for consideration for inclusion in the gazetteer.
