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.
A list of SCUFN contacts can be accessed from our Committees and Groups page.

All names selected by SCUFN are contained in the IHO-IOC GEBCO Gazetteer of Undersea Feature Names, IHO publication B-8.
The secretariat of SCUFN is provided by the Secretariat of the International Hydrographic Organization, Monaco, where the gazetteer database is maintained.
