Model study on the ecosystem impact of a variable C:N:P ratio for cyanobacteria in the Baltic Proper

It has been found that the changes in the elemental composition of cyanobacteria from constant C:N:P = 106:16:1 ratio to variable C:N:P = (106-400):(16-60):1 ratio lead to larger consumption of oxygen in the deep layers of the Baltic Proper at the long time scale (50 μM after 15 years, that amount to approximately 10%). This may be a considerable value in multi-decadal prognostic model calculations.
