Temperature regime of umbrisols, Western Spitsbergen

Abstract

The air and profile of Umbrisols in the south-western part of Svalbard are characterized by negative average annual temperatures. The duration of the period with positive temperatures at the depth of the umbric horizon (8–10 cm) is 128 days; the sum of positive temperatures is about 500 оС. The distribution of average monthly temperatures in all horizons in the profile of 0–60 cm in the annual cycle reliably correlates with air temperature.
