  1. 1. Assessing evolution of ice caps in Suðurland, Iceland, in years 1986 - 2014, using multispectral satellite imagery

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alicja Miodonska; [2019]
    Keywords : remote sensing; multispectral satellite imagery; Landsat; Iceland; glaciers; ice caps; Geography; GIS; Earth and Environmental Sciences;

    Abstract : The study focuses on the application of multispectral satellite imageries in glaciological studies. It aims to assess how the Icelandic glaciers have evolved over the last decades (from the 1980s to 2014). The study area covers Mýrdalsjökull and Eyjafjallajökull ice caps located in Suðurland, Iceland. READ MORE

  2. 2. 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

  3. 3. 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

  4. 4. Impacts of future sea level rise and high water on roads, railways and environmental objects: a GIS analysis of the potential effects of increasing sea levels and highest projected high water in Scania, Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Emilie Jideblad Arnesten; [2019]
    Keywords : geography; Geographical Information Systems; GIS; sea level; sea level rise; climate change; Earth and Environmental Sciences;

    Abstract : This study uses GIS analyses to investigate the risk that increasing sea levels and highest projected highwater pose by increasing the risk of inundation on state-owned roads and railways as well as environmental objects in their side areas. This is done through an assessment of sea level rise projections and a risk analysis, which points out where vulnerable features are located and provides timeframes and durations for the risk.

  5. 5. Change in water surface area northern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Femke Pijcke; [2017]
    Keywords : Permafrost; thermokarst lakes; climate change; northern Sweden; remote sensing; Earth and Environmental Sciences;

    Abstract : Changes in water surface area (w.s.a.) in Arctic regions have been linked to climate warming and permafrost degradation (Briggs et al. READ MORE
