Abstract

The AA. describe a new technique for the simulation of natural freezing-thawing cycles of the active layer in a permafrost microcosm. The core temperature, moisture and methane concentration and release in different depths of the microcosm can be measured continuously under controlled freezing and thawing conditions. The simulation experiment provides an insight into the activity of microorganisms and turnover rates under various cryogenic conditions (i.e. frozen, partly frozen, unfrozen). The data obtained contribute to the understanding of microbial processes and methane fluxes in permafrost environments in the autumn and early winter
