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.

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 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.
