Before revision:  We use the low-complexity FKPP model to investigate the scale-relationships in the impact of different drivers (  diffusion, mean and eddy advection, primary productivity) on the phytoplankton chlorophyll concentrations.
After revision:  We use the low-complexity FKPP model to investigate the scale-relationships in the impact of different drivers ( turbulent diffusion, mean and eddy advection, primary productivity) on the phytoplankton chlorophyll concentrations.
