White Sea catchment area: changes in soil temperature

Abstract

In the situation of climate warming, no less important than changes in air temperature are estimates of changes in soil temperature both on the surface and at different depths. The article examines the current state and changes in the thermal regime of soils in the White Sea catchment area based on long-term data from weather stations located in the study area. Changes in mean annual and monthly soil temperatures were estimated for the new reference period 1991-2020. The analysis shows that the temperatures on the soil surface and at depths have increased since the beginning of the 21st century throughout the White Sea catchment area.
