Data set shows the distribution of seabed sediments classified by genesis (Quaternary sediments). The data cover parts of the Norwegian continental shelf in Barents Sea, Norwegian Sea, North Sea and Skagerrak.

This data set contains the seabed sediments on the upper part of the bottom of the sea (upper 0-50 cm of the seabed), classified after genesis. The data set covers coastal areas in mapped areas in detailed scale. Detailing level vary between data from different mapping projects.

This dataset contains the grain size composition of seabed sediments upper part. Grain size data are based on analyzes of seabed samples, analysis and interpretation of digital reflectivity data and interpretation of analog and digital seismic data. In the attribute table of the data set, information is given about the different grain size classes based on the content of different fractions in sediments.

This dataset contains the grain size composition of seabed sediments upper part (top 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 grain sizes in sediments. Based on information about grain size distribution, other topics can be further developed, such as sedimentation environment, bottom stream data, information on hard and soft bottoms, etc.

This data set contains the distribution of seabed sediments classified after genesis in mapped areas on the Norwegian shelf. The superficial deposit surface type describes the superficial deposits genesis. The data is based on the contents of the Quaternary map which are analogous (scale 1: 250,000 to 1: 500,000), or based on digital data from modern surveying.
