Appendix L Processes: phyto losses
Once the respiration \(R_{resp\langle computed\rangle}^{phy}\) and exudation \(R_{exud\langle computed\rangle}^{phy}\) rates have been computed for a phytoplankton group via Equation (I.6) and Equation (I.12) respectively (and potentially Equation (I.7) if salinity limitation is activated), then those rates drive the mass losses of carbon, nitrogen, phosphorus and silicate. These losses are computed using a number of user specified (or default) parameters, and for each relevant computed variable, comprise the following:
- Excretion loss: Computed from a combination of respiration and exudation rates (\(R_{resp\langle computed\rangle}^{phy}\) and \(R_{exud\langle computed\rangle}^{phy}\), respectively), and
- Mortality loss: Computed from the respiration rate \(R_{resp\langle computed\rangle}^{phy}\)
The specifics of the calculation of each relevant computed variable’s excretion and mortality are described following. Losses are denoted as fluxes, \(F\).
