Due to ice wedges, segregation ice, or ice lenses, the volumetric ice content can exceed the natu- ral pore volume of the soil (i.e., excess ground ice), which [...] permafrost thaw processes in ice-rich permafrost Excess ground-ice melt: in many permafrost landscapes, ground layers super-saturated with ice occur, i.e., the volu- metric ice content exceeds the porosity [...] melting of ex- cess ground ice, but not to its aggregation, e.g., due to long- term sedimentation processes, growth of peat, or formation of ice wedges, ice lens, and segregation ice.

This is due to the special conditions in the Greenland Sea with subsurface advection
