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).
