Accumulation basins

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.

Purpose

The layer is intended to highlight selected parts of the seabed, showing accumulation areas that are characterized by weak currents and little erosion or transport of finer sediments. Knowledge of these areas may be helpful for spatial planning e.g. when planning waste emission points or aquaculture sites that require high water exchange rates.
