Heat and mass transfer in the active layer

Updated 2002-02-13

The active layer, the annually freezing and thawing upper ground in permafrost areas, is of pivotal importance. The moisture and heat transfer characteristics of this layer also determine the boundary layer interactions of the underlying permafrost and the atmosphere and are therefore important parameters input for geothermal or climate modeling. Finally, changes in the characteristics of the permafrost and permafrost related processes may be used as indicators of global ecological change provided the system permafrost-active layer-atmosphere is understood sufficiently well. The dynamics of permafrost soils is measured with high accuracy and high temporal resolution at our two sites close to Ny-Ålesund, Svalbard. Using these continuous data we quantify energy balance components and deduce heat transfer processes such as conductive heat flux, generation of heat from phase transitions, and migration of water vapor.
