This is interesting.
But in most of the world we worry more about rivers carrying too much inorganic nitrogen (mainly from agricultural runoff) to coastal seas, leading to overwhelming algal blooms, anoxia etc. So I wonder why the concern would be the other way around in the Arctic, especially as that ocean gets warmer and the ice-edge retreats, potentially giving more light and heat for the algae to grow?
I’d also guess that there are microplankton which can digest DON (organic nitrogen), so the ecosystem would shift in their favour, until the supply is rebalanced - such processes may be slow in such cold water , but again, it’s getting warmer (especially the Lena recently ).
