  1. 1. Investigating surface spring snow : Changes in the isotopic composition and conductivity along an orographic precipitation gradient in northern Fennoscandia

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Sara Andersson; [2023]
    Keywords : stable isotopes; snow; precipitation; hydrology; orography; earth science;

    Abstract : 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.

  3. 2. Glide Quality in Cross-Country Skiing : The Topographical and Frictional Impact of the Stone Grind

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Martin Johansson; [2022]
    Keywords : Friction; Stone grind; Ski development; Snow; Coefficient of Friction; Cross-Country Skiing; Ski; Friktion; Stenslip; Skidutveckling; Snö; Friktionskoefficient; Skidor;

    Abstract : 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. READ MORE

  4. 3. Snow-graupel collisions in clouds: a newly derived formulation for breakup of single crystals

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Victor Craig van der Brug; [2022]
    Keywords : Physical Geography and Ecosystem Analysis; Secondary Ice Production; Ice Cloud Number Concentration; Cloud Ice; Ice-Ice Collisions; Snow Crystal; Atmospheric Science Biogeochemical Cycles; Earth and Environmental Sciences;

    Abstract : 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. READ MORE

  5. 4. Vegetation cover change on Tindfjöll mountains, Iceland, assessed by aerial photographs, topography, and climate

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Guðrún Guðjónsdóttir; [2022]
    Keywords : Environmental changes; High Latitudes; Physical Geography; Ecosystem sciences; GIS; Climate Change; Vegetation change; Vegetation cover; Earth and Environmental Sciences;

    Abstract : 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.

  6. 5. Gribov ambiguities in non-Abelian gauge theories

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Fredrik Granström; [2021]
    Keywords : Physics and Astronomy;

    Abstract : This thesis investigates the quantization of field theories using the functional integral formalism. Gauge invariance necessitates a gauge-fixing procedure that chooses a unique field configuration from each gauge orbit. READ MORE
