Extended Data Fig. 3: Comparison of the total marine P concentration in the COPSE model versus a model which incorporates marginal settings.
From: Late Ordovician climate change and extinctions driven by elevated volcanic nutrient supply
Both models are subject to increases in riverine P input. Note that because of the single global ocean in COPSE and the nullification of marginal P recycling, it requires approximately five times the P input to drive the same increase in seawater P. Both models are initialized from a present-day steady state.
