Fig. 3: Air-sea CO2 exchange in experiments with high (Exp. 3.2) and low (Exp. 3.3) oceanic phosphate concentration.
From: Moderate greenhouse climate and rapid carbonate formation after Marinoan snowball Earth
The panels show the 10 year running mean air-sea CO2 exchange (negative into the ocean) for the years 0–200 in (a) and 200–5000 in (b). The major drivers of each excursion are annotated with text in the figure, but it should be noted that their timing and magnitude are highly dependent on the setting of the simulation and the simplifications of the model. Hence, despite showing actual simulation results, this figure should rather be seen as an illustration of the effect of the different processes on the air-sea CO2 exchange.
