Undersea feature names
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 sea floor.
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 Geophysical Data Center (NGDC).
The data are available in a number of formats including spreadsheet, shapefile, KML, WMS and ArcGIS layer and can be accessed as a REST-style API.
Find out more about the work of SCUFN, how to submit a name proposal and feature name terms and definitions from the gazetteer pages on GEBCO's web site.
