The Geo-Seas partnership comprises 30 organisations, of which 26 are data centres, managing marine geological and geophysical data sets. The other 4 organisations bring in additional expertise from specific user communities and in product development.
The project is coordinated by British Geological Survey (BGS), while the technical coordination is performed by Marine Information Service (MARIS). The following table gives all Geo-Seas partners in alphabetical order. Clicking on each name provides additional information on each organisation from the European Directory of Marine Organisations (EDMO), which is maintained by SeaDataNet.
