Marine carbon dynamics

Model : marinecarbon1

Keywords : Carbon dynamics ; Climate change ; Marine ;


This is the Anderson and Williams (1998) model, but parameterised for a station at 47N 20W in the North Atlantic (so no sediment compartment - the model has an upper mixed layer in which the ecosystem operates, and assumes a deep homogeneous layer below that).

Run the model and you’ll see that nutrient N is high over winter (the phytoplankton cannot use it because the mixed layer is deep and hence average light intensity too low), then in spring the phytoplankton (P) bloom as the mixed layer shallows and is halted when nutrients run out. There’s another bloom in autumn as nutrients are re-entrained into the surface mixed layer as it starts to deepen again.
