Approximately 970 offshore geological mapping and research sampling sites in Estonia are summarised by point data. Bottom samples are collected with Van Veen grab, Gemax corer, gravity corer or vibrocorer during seabed mapping since 1986. Information about the samples and boreholes is stored in the database of Geological Survey of Estonia.
Data are received from Estonia as a geodatabase and uploaded to the common database used by EMODnet Geology for webservices. For further details - see abstract.
