  1. 21. Diatoms from the late Holocene of the western Chukchi Sea, Arctic Ocean: environmental signals and palaeoceanography

    Master-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Erik Browaldh; [2022]
    Nyckelord :diatoms; late holocene; SWERUS-L2-2-PC1; Herald Canyon; Chukchi Sea; ice-algae; sympagic; cryophilic; warm water diatom; Bering Sea Water species; bottom water temperature; BWT; benthic foraminifera; palaeothermometry; ice dynamics; Fragilariopsis; Fossula arctica; Paralia sulcata; Shionodiscus oestrupii; Thalassiosira simonsenii; Chaetoceros; Chaetoceros sp. 7;

    Sammanfattning : The sediment Core SWERUS-L2-2-PC1 (2PC) retrieved from the Chukchi Sea, Arctic Ocean sits in an oceanographically dynamic location at the Arctic-Pacific Ocean gateway. The 8.3 m-long core was retrieved in Herald Canyon at the marginal ice zone at 57 m depth. LÄS MER

  3. 22. Analysing seasonal snow cover trends and patterns on Svalbard

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Dhruv Maniktala; [2022]
    Nyckelord :snow cover; snow disappearance; snow onset; snow-free duration; CARRA; Svalbard;

    Sammanfattning : Rapid warming in the Arctic is highly impacting the cryosphere in the region, causing melting of the sea ice, retreat of glaciers and reduction in the snow cover. If suffering further temperature increase, the albedo of the region would reduce due to higher absorption of the solar radiation in snow-free areas. LÄS MER

  4. 23. Fjällräven i ett föränderligt klimat

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Emma Marander; [2022]
    Nyckelord :fjällräv; vulpes lagopus; klimatförändringar;

    Sammanfattning : Climate change is an ongoing threat to the world´s biodiversity, and has an alarming effect on the Arctic. One species that can only be found in this particular habitat is the arctic fox, whose future is threatened by the aversive effects of global warming. The aim of this study was to investigate how climate change is affecting the arctic fox. LÄS MER

  5. 24. Tundra carbon cycling in relation to sea-ice decline in a warming Arctic

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Juliane Glinski; [2022]
    Nyckelord :sea-ice decline; warming Arctic; earlier growing season; arctic tundra; heterotrophic and autotrophic respiration; climate warming; Earth and Environmental Sciences;

    Sammanfattning : We set out to investigate whether arctic tundra acted as a sink or source of carbon dioxide (CO2) between 1980-2014 and to relate changes in the net carbon balance to Arctic sea-ice decline. We want to understand how climate change and arctic warming influence arctic carbon cycling. LÄS MER

  7. 25. Vegetation cover change on Tindfjöll mountains, Iceland, assessed by aerial photographs, topography, and climate

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Guðrún Guðjónsdóttir; [2022]
    Nyckelord :Environmental changes; High Latitudes; Physical Geography; Ecosystem sciences; GIS; Climate Change; Vegetation change; Vegetation cover; Earth and Environmental Sciences;

    Sammanfattning : Guðrún Guðjónsdóttir Climate change is having a great impact on the fragile High Latitude environment where warming is occurring at a rate at least double the global average. It is urgent to understand the relationship between climate and vegetation cover, which is playing an important role, as a carbon sink, for biodiversity, and for protecting against natural hazards.
