The dataset provides an overview of the dominant sedimentation environment in the mapped area. This is an interpretation of the processes that prevail on and near the seabed in terms of erosion, transport and deposition of sediments. Based on information about the sedimentatary environment, other thematic maps can be developed, such as bottom currents, sediment transport, pollution distribution, etc.

The map layer provides an overview of the dominant sedimentation environment in the mapped area. This is an interpretation of the processes that prevail on and near the seabed in terms of deposition, transport and erosion of sediments. The map has been digitized for use at a scales of about 1:20 000 (detailed).

Accumulation basins are the natural depressions on the sea floor with very weak bottom currents and prevailingly fine grained sediments. The renewal of bottom water in natural depressions on the seafloor my be so slow, that input of extra organic matter (f.ex. from fish farms) may result in reducing conditions.
