Carbon dioxide in the tundra soils of SW Spitsbergen and its role in chemical denudation
Measurements of CO2 concentrations in soil air were taken in the summer sea− sons of 1998 and 2001 in SW Spitsbergen. The measurements were carried out in three small non−glaciated catchments in the Hornsund region close to the Polish Polar Station. The pre− liminary measurementsw ere made using a D...
