Benthic-pelagic coupling in the Baltic Sea

When oxygen is present in the bottom water phosphorus is buried in the bottom sediments, and the amount of phosphorus available for e.g. cyanobacteria diminishes.

When oxygen is lacking phosphorus is released back to the water column – a situation that we would like to avoid and therefore also to better understand.

The study “Benthic Pelagic Coupling in the Baltic Sea: the effect of redox changes on sediment P release and implications for water quality” improved our knowledge of the mechanisms affecting the burial of phosphorus in the Baltic Sea.
