Seabed sediments (genesis) describes the geological processes behind deposition of the sediments in the uppermost 1-2 m of the seabed. The map is equivalent to Quaternary maps on land. The dataset series comprise three datasets: Seabed sediments (genesis), overview, Seabed sediments (genesis), regional and Seabed sediments (genesis), detailed. The three individual datasets are digitized in different scales and have different data coverage.

Map layer shows surface sediments (superficial deposits) on the seabed in mapped areas along the Norwegian coast. Superficial deposit as a property describes the mode of formation (genesis). The maps are digitized with a view to presentation at a scale of ca. 1:100 000 - 1:250 000 (regional mapping).

Map layer shows surface sediments (superficial deposits) on the seabed in mapped areas along the Norwegian coast. Superficial deposit as a property describes the mode of formation (genesis). The maps are digitized with a view to presentation at a scale of ca. 1:1 000 000 (overview map).

Map layer shows surface sediments (superficial deposits) on the seabed in mapped areas along the Norwegian coast. Superficial deposit as a property describes the mode of formation (genesis). The maps are digitized with a view to presentation at a scale of ca. 1:20 000 - 1:150 000 (detailed mapping). Seabed sediments classified by genesis (quaternary geology).
-
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.
-
The data set shows different landforms on the seabed on the Norwegian continental shelf and in the fjords. Examples of seabed landforms are channels, canyons, sediment waves, areas with sediment waves, glacial lineations, iceberg plough marks, moraines, slide escarpments, slide scars, slide areas, areas with slide deposits, submarine fans and areas with pockmarks.
