Sources & Sinks: A Tale of Coastal Biogeochemistry - BONUS COCOA
New COCOA publication!
Lenstra (Utrecht University) and co-workers wanted to know, which mechanisms
control the burial of phosphorus in coastal sediments, as phosphorus is known
to enhance growth of phytoplankton and burial is the only long-term sink in
They found that phosphorus burial in the northern Baltic Öre Estuary was high compared to other areas in the Baltic Sea and that burial was strongly enhanced by the formation of iron(II)- phosphorus minerals within the sediment. Additionally, they showed that iron input from the Öre River was strongly linked to variations in river discharge: Iron fluxes from the river were highest after dry periods on land, which strongly impacted the phosphorus burial in the Öre Estuary.
