Fig. 5: Summary of modeling results.

Model simulation results after 100 years (a, b) and after 200 years (c-d). Cumulative anaerobic oxidation of methane (AOM) filter efficiency (a, c) and cumulative gas escape (b, d) plotted against intrinsic permeability for Case A (baseline, blue) and Case E (no AOM, black). Note that the blue line is essentially hidden behind the black in (b), meaning that AOM has a negligible mitigating effect on seafloor emissions over the first 100 years.
