(a) Methane mass flux vs. time: simulation 1–7: 1a – ∆T = 10 °C (without self-preservation); 1b – ∆T = 10 °C (with self-preservation); 2–15 °C; 3–20 °C; 4–25 °C; 5–30 °C; 6–40 °C; 7–70 °C; experiment 8 – ∆T = 10 °C. (b) Dissociation of methane hydrate: Curve 1(experiment from presented paper); Curve 2 (experiment from refs ¹⁵ and ⁷⁷); 3 – simulation.
