  1. 21. Globala uppvärmningens påverkan på isbjörnens parasiter

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Rebecca Söderberg; [2016]
    Keywords : Isbjörn; parasiter; global uppvärmning; Polar bears; parasites; global warming;

    Abstract : Globala uppvärmningen är ett aktuellt problem och ett djurslag som påverkas framförallt av klimatförändringarna är isbjörnen (Ursus maritimus). På det cirkumpolära Arktis använder de havsisarna som plattform för att bedriva jakt, reproduktion och förflyttningar. READ MORE

  2. 22. Changes in Surface Mass Balance on the Devon Ice Cap in the Canadian Arctic

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : Linnéa Midefelt; [2016]
    Keywords : Surface mass balance; Devon Ice Cap; Canadian Arctic; Physics and Astronomy;

    Abstract : Climate change is an ongoing process that contributes to changes in the climate on a global scale down to a local scale. The Arctic sea ice and the glaciers have continued to decrease at the same time as the rate of sea level rise has increased. READ MORE

  3. 23. Arctic sea ice drift - A comparison of modeled and remote sensing data

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Stina Karlsson; [2016]
    Keywords : Physics and Astronomy;

    Abstract : The Arctic climate and the sea ice drift are important to study both for the improvement in short-term forecasts and to get a better understanding of the climate change. Short-term forecasts are needed to improve the shipping and offshore industries in the Arctic Ocean. READ MORE

  4. 24. Snow and sea ice temperature profiles from satellite data and ice mass balance buoys

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Isabella Grönfeldt; [2016]
    Keywords : IMB; ice mass balance buoys; snow-ice interface; air-snow interface; temperature profile; snow; sea ice; Fram Strait; Greenland; Arctic Ocean; climate change; climate; physical geography and ecosystem analysis; remote sensing; satellite; sensor; SMOS; AMSR-2; TIR; numerical weather prediction; multiple regression analysis; Earth and Environmental Sciences;

    Abstract : The sea ice covers approximately 5% of the Earth’s surface at any given time and it plays an important role in the polar climate system affecting the heat, mass and momentum exchange between the atmosphere and the ocean. The snow cover on top of the sea ice affects its insulating and reflective properties and thus key figures in the climate system feedback loop. READ MORE

  5. 25. Applying GIS to Investigate the Spatial Variability of Sub-Glacial Hydrology under Land Terminating Ice Sheets in Western Greenland Ice Sheet.

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Welsh Samuel; [2016]
    Keywords : Hydraulic potential; Greenland; GIS; sub-glacial hydrological network; ice sheet dynamics; Hydraulisk potential; Grönländ; GIS; sub-glacial hydrologi; istäckesdynamik;

    Abstract : With continued warming regional surface air temperatures around the Artic in recent decades, there is growing importance in understanding how ice sheet dynamics interact with a shifting global climate system. This research investigates the spatial variability of sub-glacial hydrology under land terminating ice sheets in Western GrIS, when applying varying overburden ice pressures within Shreve’s (1972) hydraulic potential equation.
