1. Estimating active layer thickness at the high Arctic study site Zackenberg from remotely sensed ground subsidence
Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : 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.

2. Change in water surface area northern Sweden
Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Changes in water surface area (w.s.a.) in Arctic regions have been linked to climate warming and permafrost degradation (Briggs et al. LÄS MER
3. Investigating Seasonal Snow in Northern Sweden – a Multi-Layer Snow Pack Model and Observations from Abisko Scientific Research Station Provide Clues
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Meteorological parameters determine the physical properties of snow precipitating from the atmosphere, but snow layers also continue to develop within the snow pack after the precipitation event. New characteristics form depending on temperature fluctuations, interaction with the soil, overburden compression, rain-on-snow events and more. LÄS MER
4. Influence of soil moisture content and infiltration on ground temperature and active layer depth in a river terrace in Adventdalen, Svalbard
Master-uppsats, Stockholms universitet/Institutionen för naturgeografiSammanfattning : The active layer constitutes an important subsystem of permafrost environments. Thermal andhydrological processes in the active layer determine local phenomena such as erosion, hydrologicaland ecosystem changes, and can have implications for the global carbon-climate feedback.

5. De-icing and ice prevention of automotive headlamps and tail lamps : - An investigation of techniques and development of a test method
Master-uppsats, KTH/Farkost och flygSammanfattning : The work aims to study different methods suitable for de-icing and ice prevention of vehicle headlamps and tail lamps, especially LED-lights. Furthermore, the work aims to investigate the scale of the problem with insufficient or lack of de-icing on automotive lamps depending on the region and the environment the vehicle operates in.
