The dataset has been interpreted and digitized by NGU. The source data for interpretations is data from the Norwegian Geological Survey (NGU), the Norwegian Mapping Authority (SKS), the Institute of Marine Research (HI), the Norwegian Defence Research Establishment (FFI). Grain size data is based on interpretation of video of the seabed, interpretation of digital reflectivity data, as well as interpretation of analogue and digital seismic data. Acoustic data and video are verified with analyses of sediment samples. Detailed bathymetry data has been included to support the interpretation. Seabed sediments (grain size) has been digitized and prepared using ArcGIS tools. The methodology is described in the ‘Målemetode’ and ‘Geopåvisningtype’ fields.

The data set shows the grain size composition in the upper part of the seabed sediments (upper 0-50 cm of the seabed). The attribute table for the data set provides information on the different grain size classes and which term is used based on the content of different fractions in sediments. By applying different symbologies designed to show the content of individual particle size fractions, the dataset can be displayed as a series of more specialized maps, e.g. Sediment mud content or Dominant grain size.
