Appendix K Processes: phyto uptake
Once the primary productivity \(R_{prod\langle computed\rangle}^{phy}\) rate has been computed for a phytoplankton group via Equation (I.2) (and potentially Equations (I.3) and (I.4) if nitrogen fixing and salinity limitation are activated, respectively), then that rate drives the mass uptake of inorganic carbon, nitrogen, phosphorus and silicate. This uptake includes the operation of a number of user specified (or default) parameters, and the respective calculations are described following. Uptakes are denoted as fluxes, \(F\).
