Figure 8

(a) History of permafrost and GH P-T stability in the early 5000 years of immersion. History of surface forcing is shown in the upper panel (from subsea −1°C to harsh arctic terrestrial temperature condition of −20°C). (b) Corresponding modeled temperature versus depth (T-z) given for a set of times after the sea to terrestrial onset. The initial profile is a steady-state one corresponding to the marine setting conditions.
