  1. 16. Analysis of Arctic peak-season carbon flux estimations based on four MODIS vegetation products

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Antonin Kusbach; [2016]
    Keywords : satellite-derived data; vegetation indices; Arctic; net ecosystem exchange; big data analysis; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

    Abstract : Increased temperatures in high latitudes may alter the carbon dynamics throughout the Arctic. Modelled CO2 simulations show that current climate conditions constitute the Arctic a net carbon sink, though the large extent and fine landscape heterogeneity raise an uncertainty about the carbon sink/source status of the region.

  2. 17. Analysis of the Temporal Variability of Positive Degree Day Factors

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

    Author : Hanna Rönnberg; [2016]
    Keywords : Positive Degree Day Surface Mass Balance; Physics and Astronomy;

    Abstract : The surface mass balance determines the growth or decay of an ice sheet, by taking the difference between accumulation and ablation. In this thesis snow and ice ablation is related to 2m-temperature through the positive degree day method. READ MORE

  3. 18. Size-dependent airborne particle emissions from ship traffic

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

    Author : Fredrik Mattsson; [2016]
    Keywords : Aerosol particle; shipping; emission; health effect; particle number concentration; particle number size distribution; Physics and Astronomy;

    Abstract : Most aerosol particles emitted from shipping affect the climate by counteracting the greenhouse effect. Although, this masks the warming effect of greenhouse gases, aerosol particles also have a negative health effects, and therefore emissions need to be reduced. READ MORE

  4. 19. 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

  5. 20. 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
