  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. Snow depth measurements and predictions : Reducing environmental impact for artificial grass pitches at snowfall

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM); Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Findlay Forsblom; Lars Petter Ulvatne; [2020]
    Keywords : artificial grass; rubber granulate pollution; snow depth measurement; snow level prediction; temperature index; energy index; energy balance model; machine learning; python; random forest; ultrasonic sensor; infrared sensor; lorawan; pycom lopy4; micro python; arduino uno; web application; javascript; node.js;

    Abstract : Rubber granulates, used at artificial grass pitches, pose a threat to the environment when leaking into the nature. As the granulates leak to the environment through rain water and snow clearances, they can be transported by rivers and later on end up in the marine life. Therefore, reducing the snow clearances to its minimum is of importance. READ MORE

  3. 3. 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

  4. 4. 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.

  5. 5. 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
