Sources & Sinks: A Tale of Coastal Biogeochemistry - BONUS COCOA
New COCOA publication!
A new study from BONUS COCOA is out:
(Institute for Baltic Sea Research Warnemuende) and co-workers wanted to know whether river plume and bottom boundary layer in
the coastal zone are potential hotspots for
nitrification, due to their favorable characteristics. Nitrification is a key process in the coastal nitrogen cycle:
the produced nitrate can either be substrate for primary production whereby
nitrogen stays in the coastal system, or for denitrification whereby nitrogen
is removed from the coastal system.
They found that neither river
plume nor BBL of the Vistula Estuary in the southern Baltic Sea are hotspots for
nitrification. Instead, short term changes such as sediment re-suspension during
a storm event or oxygenation of anoxic water can significantly enhance nitrification.
