  6. 5. Soil organic carbon storage, distribution and characteristics in two contrasting permafrostaffected environments : Evaluating the role of alpine and lowland tundra areas in the permafrost carbon feedback

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Didac Pascual; [2018]
    Keywords : soil organic carbon; permafrost; tundra; alpine; climate change; feedback; mapping; landcover; landform;

    Abstract : An important portion of the large northern permafrost soil organic carbon (SOC) pool might be released into the atmosphere as greenhouse gases following permafrost thawing and subsequent SOC decomposition under future warming conditions, resulting in a warming amplification known as the permafrost carbon feedback. Improved knowledge about the amount, composition and distribution of the permafrost SOC pool is essential when assessing the potential magnitude and timing of the permafrost carbon feedback. READ MORE
