21. Paleoglaciological study of the Ahlmannryggen, Borgmassivet and Kirwanveggen nunatak ranges, Dronning Maud Land, East Antarctica, using WorldView imagery
Master-uppsats, Stockholms universitet/Institutionen för naturgeografiSammanfattning : Paleoglaciological reconstructions based on glacial geological and geomorphological traces are used to test and constrain numerical models of ice sheet extent and dynamics. MAGIC-DML (“Mapping, Measuring and Modelling Antarctic Geomorphology and Ice Change in Dronning Maud Land”) project is trying to reconstruct the timing and pattern of ice surface elevation changes since the mid-Pliocene across western Dronning Maud Land, East Antarctica.

22. 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
23. Different generation of controlled moraines in the glacier foreland of Midtdalsbreen, Norway
Master-uppsats, Stockholms universitet/Institutionen för naturgeografiSammanfattning : A series of small mounds (< 3m) were sampled in the foreland of Midtdalsbreen outlet glacier, southern Norway. These landforms were interesting, especially at site number 1 because they were located very close to a higher Little Ice Age (LIA) moraine (> 5 m), thereby informing the dynamic of the glacier after the LIA at this location.

25. A Risk Assessment Analysis : The risk of saltwater intrusion into freshwater wells and the effects of a futuresea level rise on the Baltic Sea island of Öland
Kandidat-uppsats, Stockholms universitet/Institutionen för naturgeografiSammanfattning : Freshwater is essential for a functional society and the human well-being. However, it should not be taken for granted. Freshwater aquifers in coastal are subject to current and future risk of becoming saltwater contaminated – reaching a tipping point. Freshwater security on islands is vulnerable. LÄS MER
