The map layer shows grain size composition in upper part of seabed sediments (upper ca 50 cm of the seabed). Grain size as a property describes the percentage of different grain size classes in a sediment or superficial deposit type. The maps are digitized with a view to presentation at a scale of 1:20 000 - 1:150 000 (detailed mapping).

The map layer shows grain size composition in upper part of seabed sediments (upper ca 50 cm of the seabed). Grain size as a property describes the percentage of different grain size classes in a sediment or superficial deposit type. The maps are digitized with a view to presentation at a scale of 1:1 000 000 (overview map).

The map layer shows grain size composition in upper part of seabed sediments (upper ca 50 cm of the seabed). Grain size as a property describes the percentage of different grain size classes in a sediment or superficial deposit type. The maps are digitized with a view to presentation at a scale of 1:100 000 (regional 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. 1:1 000 000 (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. 1:100 000 - 1:250 000 (regional mapping).
