Short summary
A simple modification to the existing methodology for calculating biological production in global ocean model is proposed here. A space- and time-varying production depth is found in the upper few metres of the ocean based on sunlight and nutrient availability. This new method is tested for Indian Ocean biological production zones. With this new method the carbon cycling in the surface of the Indian Ocean is simulated better in the model. A reason for the improvement is detailed in the paper.
