  1. 1. Greenhouse gas emissions from peat soil thawing in spring : a comparison between fertilized and unfertilized soil

    University essay from SLU/Dept. of Soil and Environment

    Author : Fanny Otterlin Karlsson; [2024]
    Keywords : agricultural soil; carbon dioxide; freeze-thaw cycles; nitrous oxide; soil temperature; water content;

    Abstract : Peat soils drained for agriculture and forestry contribute to a significant amount of greenhouse gas emissions. Nitrous oxide is a greenhouse gas with high warming potential and agriculture in general accounts for about 70 % of nitrous oxide emissions. READ MORE

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Namika Maharjan; [2023]
    Keywords : Advanced Terrestrial Simulator ATS ; hillslope connectivity; tracer test; hydrological modeling; parameter analysis; sub artic regions; hillslope hydrology;

    Abstract : The Sub artic regions are becoming increasingly important due to the effects of climate change. In northern Sweden, thawing of permafrost has led to significant increases in annual minimum flows in several catchments. READ MORE

  4. 3. Applying LPJ-GUESS on the Arctic: A model evaluation and benchmarking study

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Margot Jeanne Knapen; [2023]
    Keywords : Physical Geography and Ecosystem Analysis; LPJ-GUESS; Arctic; FLUXNET; Gross Primary Productivity; Ecosystem Respiration; Permafrost; Active Layer Thickness; Snow Depth; Earth and Environmental Sciences;

    Abstract : Warming in the Arctic occurs at a much higher rate than the global average, which has a considerable impact on the Arctic terrestrial carbon cycle. Permafrost thawing can release substantial amounts of carbon, whilst tundra shrubification and tree-line advance, on the other hand, may compensate for this. READ MORE

  5. 4. Temperaturens inverkan på tillväxt av olika mikroorganismer på frysta livsmedel

    University essay from SLU/Department of Molecular Sciences

    Author : Almohannad Alahmad; [2022]
    Keywords : Frysning; ; förskämning; hållbarhet; mikroorganism; upptining;

    Abstract : Metoder för att bevara mat har varit en viktig aspekt för att säkra livsmedelsförsörjningen genom historien. Frysning och andra konserveringsmetoder har använts med framgång under årens lopp för att förlänga livsmedels hållbarhetstid, men det finns ibland mikroorganismer på livsmedel som kan växa till mängder som kan leda till sjukdom och utgöra problem för individers hälsa, eller så kan de förskämma livsmedel.
