Climate change affects Arctic regions by exposing previously frozen permafrost to thaw and changing hydrological processes. As a result, permafrost soils in Arctic have recently developed unfrozen soil portions in winter. These unfrozen soil portions may increase the soil biogeochemical connectivity...
