Seabed sediments - Grain size

Seabed sediments (grain size) show the grain size composition in the upper part (upper 0-50 cm) of the seabed. The dataset series comprise three datasets: Seabed sediments (grain size), overview, Seabed sediments (grain size), regional and Seabed sediments (grain size), detailed. The three individual datasets are digitized in different scales and have different data coverage.

The data of this dataset series can be used as basis for decision making in the overall land use and environmental planning, habitat mapping, vulnerability analyzes, impact analysis in connection with installations on the seabed etc. Map showing sediments classified by grain size gives a good overview of the depositional environment and seabed conditions.

Explanation of assessment of FAIR principles:

There have made various tests to evaluate datasets in relation to the FAIR criteria. These are our interpretations, which then assess the criteria in relation to standards and protocols used for spatial data in Norway and Europe. For more information on which calculations we use for each indicator, look at the details of FAIR assessments for each specific dataset.

FAIR status: 77%
