The dataset provides an overview of sedimentation rates in the upper ten centimetres of seabed sediments in the North Sea and Skagerrak. Results are quantitative and were estimated with spatial modelling methods. Uncertainties of the estimates are provided as well.

The dataset provides an overview of organic carbon concentrations in the upper ten centimetres of seabed sediments in the North Sea and Skagerrak. Results are quantitative and were estimated with spatial modelling methods. Uncertainties of the estimates are provided as well.
-
Shell sand occurrences show areas in the coastal zone with information about shell sand on the seabed, either based on mapping in the field or modeling. Sediments with a calcium carbonate content > 50% and consisting of whole or crushed calcerous shells are described as shell sand or shell gravel.
-
Modelled biotopes in the NordlandVI area. MAREANO video data were to determine the biological communities and this information was put together with bathymetry, terrain and geological data to model the overall distribution of biotopes. Nine biotopes have been identified in the area through the use of multivariate statistics.
-
Distribution of shell sand localities based on modelling. Modelling is based on data collected by NGU, and carried out by NIVA, in the frame of nation program for mapping of biological diversity.
-
Modelled biotopes on the Mid-Norwegian Shelf. Seven biotopes have been identified in the area through the use of multivariate statistics, based on bathymetry, geology and dominating fauna.
-
Index layer showing the areas where mapping and/or modelling of shell sand is carried out.
-
Modelled biotopes on the TromsII/NordlandVII area. Analyses of species counts from 222 video transects has allowed to identify ten different biotopes in Troms II/ Nordland VII area. Geological, morphological and oceanographic variables have been used for spatial prediction of the distribution of biotopes across area.
