New estimate from BONUS COCOA: The coastal filter permanently removes more than half of the phosphorus entering the Baltic Sea and one-sixth of the nitrogen

Based on the new results published in a special issue of Limnology and Oceanography journal last week, BONUS COCOA estimates that the coastal filter in the Baltic Sea removes 16% of nitrogen and 53% of phosphorus inputs from land. Nutrient removal rates are specific to ecosystem types: lagoons are hot spots for denitrification and archipelagos for phosphorus burial. In fact, archipelagos act as important phosphorus traps which account for as much as 45% of the coastal phosphorus removal despite them covering only 17% of the coastal areas of the Baltic Sea. Such high burial rates could be partly sustained by phosphorus import from the open Baltic Sea.
