11. Inferring runoff generation processes in a discontinuous permafrost catchment in northern Sweden using hydrometric, isotopic, and modeling methods
University essay from Stockholms universitet/Institutionen för naturgeografiAbstract : .... READ MORE

12. Influence of permafrost disintegration on wetland carbon fluxes in Abisko, Sweden
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The northern permafrost regions are experiencing a rapid warming as surface temperatures are rising, causing a disintegration of permafrost and a deepening of the active layer (AL). This releases previously frozen carbon, making it available for decomposition by microbes. READ MORE

13. Estimating active layer thickness at the high Arctic study site Zackenberg from remotely sensed ground subsidence
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The active layer thickness (ALT) is an indicator of permafrost thaw, which potentially leads to the release of large amounts of greenhouse gases under global warming, and thus could further amplify climate change. The thaw depth of the active layer also governs seasonal surface deformation, caused by the volume change between ice to water, which poses risks for slope stability and infrastructure foundations.

14. Traits of peat- and upland-derived stream dissolved organic carbon in the permafrost region around Abisko, northern Sweden
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Climate change-induced thawing of permafrost mobilizes previously frozen carbon of high potential reactivity, thereby, fuelling microbiological production of greenhouse gases. For this work, an analysis of the quantity, quality, and bioreactivity of DOC in streams from the Stordalen discontinuous permafrost catchment was carried out with stream water samples during the relatively warm summer of 2018.

15. Carbon Storage in Quaternary Deposits of the Circum-Arctic Permafrost Region
University essay from Stockholms universitet/Institutionen för naturgeografiAbstract : Rapid warming in northern latitudes will lead to permafrost thaw and subsequent carbon remobilisation and release to the atmosphere. To incorporate the permafrost carbon climate feedback in globalEarth System Models, it is of importance to know the carbon stored in the circumArctic permafrostregion as accurate and precise as possible.
