1. Investigating surface spring snow : Changes in the isotopic composition and conductivity along an orographic precipitation gradient in northern Fennoscandia
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Stable isotopes of oxygen (O18) and hydrogen (H2) are used as proxies of past climates when ice preserved in the polar icecaps. The main assumption when doing paleoclimatic reconstructions using these isotopes is that the isotopic composition of the snow that turned into ice reflect the present temperature of the planet during deposition.

2. Karakterisering av ytstrukturen på en alpinskidas belag : Undersökning av alpinskidas struktur med mikroskopiundersökning och glidtes
Kandidat-uppsats, Mittuniversitetet/Institutionen för kvalitets- och maskinteknikSammanfattning : Forskning och karakterisering av alpinskidors belag kräver mycket tid och resurser att utföra därav försvinner informationsmängd inom området, då de tester som görs inte delas offentligt. Idag användsuteslutningsmetoden mycket och inte mätvärden som testats fram. LÄS MER
3. Glide Quality in Cross-Country Skiing : The Topographical and Frictional Impact of the Stone Grind
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälleSammanfattning : The Swedish Winter Olympic team is one of the strongest Olympic teams in theworld, and the majority of the team’s success comes from ski-related sports. So howcan the Swedish team remain, and maybe even accelerate, its competitive advantage? The answer is science. LÄS MER
4. Snow-graupel collisions in clouds: a newly derived formulation for breakup of single crystals
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : The observed and well-known discrepancy between concentrations of ice nucleating particles in the environment and the concentrations of ice particles in clouds show that there are additional ‘secondary’ processes enhancing the concentrations of ice particles. In present-day modelling of weather and climate, such processes are mostly overlooked and thus a cause for uncertainty. LÄS MER
5. Vegetation cover change on Tindfjöll mountains, Iceland, assessed by aerial photographs, topography, and climate
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Guðrún Guðjónsdóttir Climate change is having a great impact on the fragile High Latitude environment where warming is occurring at a rate at least double the global average. It is urgent to understand the relationship between climate and vegetation cover, which is playing an important role, as a carbon sink, for biodiversity, and for protecting against natural hazards.
