When the project “For a Living Coast” started in 2010, the Björnö bay was one of the most eutrophic bays in Stockholm's archipelago. Most nutrients came from the bottom sediments - old releases of phosphorus stored in the ground for decades, were slowly released back into the water, contributing to eutrophication. Today there is no phosphorus release from the bottom sediments and the bay is no longer eutrophied. In the article "Phosphorus bound in sediment" we present the measure that have stopped the release of nutrients from the bottom sediments and helped the bay to regain good water quality.
