Figure 6: Simulation of bottom seawater temperature propagation.

Results of the seasonal heat propagation model with historic bottom water temperatures. (a) The average temperature in this area is 1.25 °C with fluctuations between −1.5 and 5 °C. (b–m) Monthly sub-bottom temperature profiles from our model. Seasonal bottom water temperature fluctuations only disturb the sub-bottom gas hydrate shallower than ∼1.65 mbsf (blue area from e–i). Our recovery of gas hydrate in May and October, however suggest gas hydrate dynamics do not respond quickly to the seasonal temperature fluctuations.
