  1. 1. Ash distribution and cavities in Icelandic glaciers, a marker for snow accumulation and radar signal velocity change

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Andrea Håkansson; [2020-01-15]
    Keywords : Iceland; GPR; CMP; Glacier; Vatnajökull; Háabunga; Langjökull;

    Abstract : Glaciers in the geologically active Iceland has a high scientific as well as touristic value.In this thesis, the two largest glaciers on Iceland have been studied with GPR to find ifthe method is suitable to use in future glaciolocial studies where accumulation patternsand similar attributes are in focus in a world of deglaciation.

  2. 2. REAL-TIME RENDERING OF DEFORMABLE SNOW COVERS

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Josefin Svensson; [2019]
    Keywords : ;

    Abstract : Rendering snow environments in real-time requires e‚ffective methods for representing the snow and its properties. ‘This thesis explores methods for rendering deformable snow covers, where a dynamic heightfi€eld is used for storing snow heights. Collision detection for cylinder geometries is used to generate tyretracks from wheels. READ MORE

  3. 3. Using camera traps to identify the influence of seasonal climate variations on the passage rates of a multi-species ungulate community in Öster Malma, Sweden

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Nicholas Varley; [2019]
    Keywords : ungulates; passage rates; temperature; snow depth; camera trap;

    Abstract : Future climate change projections have consistently shown that globally we are heading for hotter summers, milder winters and less precipitation. Climate changes such as increasing temperatures will have an impact on the behaviour and distribution of both flora and fauna with shifts in their ranges in accordance with their climate boundaries.

  4. 4. Snow insulation effects across the Arctic : evaluating a revised snow module in LPJ-GUESS

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alexandra Pongrácz; [2019]
    Keywords : active layer depth; Arctic; LPJ-GUESS; snow; soil temperature; Earth and Environmental Sciences;

    Abstract : The effect of future changes in temperature and precipitation patterns on arctic ecosystem functioning is often assessed using state-of-the-art ecosystem models. Many models however lack detailed representation of wintertime processes, as pointed out by recent studies (Wang et al. 2016, Slater and Lawrence 2013). READ MORE

  5. 5. Direct multispectral photogrammetry for UAV-based snow depth measurements

    University essay from KTH/Geoinformatik

    Author : Kathrin Maier; [2019]
    Keywords : Unmanned Aerial Vehicles UAV ; snow depth; direct photogrammetry; multispectral imagery; cryosphere;

    Abstract : Due to the changing climate and inherent atypically occurring meteorological events in the Arctic regions, more accurate snow quality predictions are needed in order to support the Sámi reindeer herding communities in northern Sweden that struggle to adapt to the rapidly changing Arctic climate. Spatial snow depth distribution is a crucial parameter not only to assess snow quality but also for multiple environmental research and social land use purposes. READ MORE
