National database for ground investigations (NADAG) shows borehole (points) where ground surveys are carried out. NADAG includes geotechnical data (boreholes) and has a view service for this. The services NADAG offers are free.

The application Geological heritage displays registered geological localities that may be of interest for tourists, students, wildlife managers and local communities. Some of the material is of older age and the quality of information at each locality may vary. We welcome your comments and corrections to the data, or suggestions to new localities.

Naftalen, fenantren, dibenzotiofen and alkylerte homologer: Summed levels of Naftalen, fenantren, dibenzotiofen and their alkylated homologs in surfrace sediments, in µg/kg dryweight. Mareano maps debt, bottom status, nature type and pollution in norwegian ocean areas, see mareano.no

Thickness of the sedimentary cover on the bedrock (Quaternary sediments) and thickness of sediments accumulated after the last ice age (Holocene sediments).

Dataset comprises polygons of 1x1km, each square km bearing information of the number of probable occurrences of coral reefs within it (occurrence density).

Sediment genesis. Seabed sediments on the Norwegian Continental Shelf classified by genesis (quaternary geology).

Probable occurrences of coral reefs on Norwegian Continental Shelf, where the attributes 'palitelighet' and 'code' indicate whether automatic classification of the occurrence has high or low confidence. This dataset is one of four datasets created by the automatic classification of detailed bathymetry data.

Sediment particle size. Grain size composition of the top layer of the seabed sediments in the marine areas of Norway. Data is obtained from many different mapping projects, hence the varying details on the map layers (overview, regional and detailed).

Naphthalene: Concentrations of naphthalene in surface sediments, in µg/kg dry weight. Mareano maps debt, bottom status, nature type and pollution in norwegian ocean areas. see mareano.no

Bottom reflectivity. Acoustic baskscatter. The strength of the acoustic signal reflected back from the seabed. It gives an indication of the nature of the seabed (soft or hard). Data aquired with differend equipment (multibeam echosounders and 3D-seismic technology).
