The map layer shows the spread of bioclastic sediments consisting of particles formed from the decomposition of mainly calcareous organisms, and may contain all grain sizes from clay to block. The map layer contains no information about the proportion of living and dead organisms.
-
The map layer shows areas with detailed sediment maps (grain size).
-
The map layer shows areas with detailed sediment maps (genesis).
-
Acoustic backscatter. Bottom reflectivity mapped with multibeam echosounder, 50 m grid. The strength of the acoustic signal reflected back from the seabed.
-
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).
-
Sediment thickness above bedrock on the Norwegian continental shelf.
-
The map layer presents several thousand points with bottom information (grain size and sediment type) in fjords and coastal areas.
-
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).
-
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).
-
Main direction of bottom currents interpreted on the basis of the distribution pattern of sediment types.
