1. THE INFLUENCE OF TUNDRA VEGETATION ON SOIL TEMPERATURES
Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskapSammanfattning : The arctic has experienced more rapid global warming and is more sensitive to temperature changes compared with the rest of the world. We can already see how vegetation distributed across the arctic tundra has changed in composition, height, and abundance. LÄS MER
2. 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
Magister-uppsats, Stockholms universitet/Institutionen för naturgeografiSammanfattning : 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. LÄS MER
3. Probability Modelling of Alpine Permafrost Distribution in Tarfala Valley, Sweden
Kandidat-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : Datainsamling har genomförts i Tarfaladalen under 5 dagar vid månadsskiftet mellan mars och april 2017. Insamlingen resulterade i 36 BTS-mätningar (Bottom Temperature of Snow cover) som därefter har använts tillsammans med data från tidigare insamlingar, till att skapa en sammanställd modell över förekomsten av permafrost omkring Tarfala.

4. Near-Surface Energy Balance on an Alpine Rock Glacier: Murtèl-Corvatsch
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : This project investigates the near surface energy balance on the Murt`el-Corvatsch rock glacier in the Upper Engadine, Swiss Alps, using the 1D physical SNOWPACK model. A correct representation of the near surface energy balance is important to predict the long term evolution of permafrost below rock glaciers. LÄS MER
