This WMS map layer shows selected areas from the dataset "Seabed sediments (grain size), detailed" and indicates where fine sediments are likely to accumulate due to weak bottom currents. Such areas are typically dominated by silty and/or clayey and may include areas with fine-grained sediment deposited on top of coarser material. The map layer is intended for use at map scales 1:10 000 – 1:50 000.

The map service presents a number of thematic layers derived from detailed basis information about the seabed: depth and sediment composition. The following themes are visualized: Bathymetry (terrain), Slope, Anchoring, Diggability, Accumulation basins and Habitats.
