   Sammanfattning : This thesis outlines the development and decay of palsas in northern Sweden in relation to climatic and environmental factors. Palsas were investigated on morphology, vegetation, peat porosity, ground temperature and local climate in four bogs situated on a north-south gradient in northern Sweden. LÄS MER

3. 2. High-resolution mapping and spatial variability of soil organic carbon storage in permafrost environments

   Författare :Matthias Benjamin Siewert; Gustaf Hugelius; Peter Kuhry; Iain Hartley; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbon; soil organic carbon; permafrost; soil; land cover classification; digital soil mapping; machine-learning; ecosystem; mapping; landscape studies; Siberia; Arctic; Physical Geography; naturgeografi;

   Sammanfattning : Large amounts of carbon are stored in soils of the northern circumpolar permafrost region. High-resolution mapping of this soil organic carbon (SOC) is important to better understand and predict local to global scale carbon dynamics. LÄS MER
