1. Legacy effects of temperature alterations on microbial resistance and resilience to drying and rewetting
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : With warming in soils due to climate change, a series of secondary factors arise, which have multifaceted effects on soil microbial communities. Of these, alterations to soil moisture are among the most crucial to understanding how microbial functions will change in the face of climate change. LÄS MER
2. 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
3. Vetenskapen : - En Forskningsstation i Tarfala
Uppsats för yrkesexamina på avancerad nivå, KTH/ArkitekturSammanfattning : Utan att forskarna riktigt kunde förklara varför stod det helt klart under 1900-talets första hälft att isarna blev mindre. På hela norra halvklotet blev glaciärerna allt mindre och denna storlekförändring sattes i samband med den temperaturökning som skett under samma tid. LÄS MER
4. Object-Based Classification of Vegetation at Stordalen Mire near Abisko by using High-Resolution Aerial Imagery
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : 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.

5. Time series analysis of ground frost conditions at Abisko, sub-Arctic Sweden, 1985-2010
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Observed climatic change may result in modification of the ground thermal regime.The causes of shallow ground temperature variability, however, are not well documented. LÄS MER
