1. Evaluating DInSAR for measuring seasonal elevation dynamics at the Vissátvuopmi palsa mire complex in Northern Sweden
University essay from Göteborgs universitet/Institutionen för geovetenskaperAbstract : During recent years the palsa mires of Fennoscandia have reported to be undergoing extensive lateral degradation, and in a warming environment the palsa mires of Sweden among others are threatened to thaw completely by the end of this century. Since subarctic peatlands account for 30% of the global soil organic carbon storage, small degradation changes in these areas globally, can potentially change the greenhouse gas emissions on a worldwide scale.

2. Object-Based Classification of Vegetation at Stordalen Mire near Abisko by using High-Resolution Aerial Imagery
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The focus of this work is to investigate and apply the remote sensing method of object-based image analysis (OBIA) for vegetation classification of a permafrost underlain peatland in sub-arctic Sweden, by using aerial imagery of high resolution. Since the northern landscapes are an important source of naturally stored CH4 and CO2, their contribution to the global carbon cycle is a focus in research about climate change and the global methane exchange.

4. Subarctic peatlands in a changing climate : greenhouse gas response to experimentally increased snow cover
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The rate of change of our climate has been amplified since the industrial revolution and is expected to change even further by the end of this century. Global temperature and precipitation are expected to increase considerably over the next century. These increases are expected to be magnified in the Arctic regions. READ MORE
