Isotopic model of oceanic silicon cycling: The Kerguelen Plateau case study

► Simple conceptual non-steady state box model for the cycling of Si-isotopes. ► Included processes: uptake, dissolution, advection, vertical mixing and settling. ► Model applied to Kerguelen Plateau area to simulate growth season. ► By fitting to (scarce) data, processes rates can be estimated simultaneously. ► Sensitivity study shows robustness of model.
