Shoreface of the Arctic seas - a natural laboratory for subsea permafrost dynamics
Subsea permafrost on the Arctic shelf occupies some 13 million km2, but is poorly understood. Mathematical modeling, based on the differential equation of heat conduction, is widely used for the compilation of predictive permafrost maps. Realistic geocryological conditions on the Arctic shelf cannot...
