1. 1. Investigating surface spring snow : Changes in the isotopic composition and conductivity along an orographic precipitation gradient in northern Fennoscandia

   Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Sara Andersson; [2023]
   Nyckelord :stable isotopes; snow; precipitation; hydrology; orography; earth science;

   Sammanfattning : Stable isotopes of oxygen (O18) and hydrogen (H2) are used as proxies of past climates when ice preserved in the polar icecaps. The main assumption when doing paleoclimatic reconstructions using these isotopes is that the isotopic composition of the snow that turned into ice reflect the present temperature of the planet during deposition.

3. 2. Evaluating DInSAR for measuring seasonal elevation dynamics at the Vissátvuopmi palsa mire complex in Northern Sweden

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :André Farjami; [2022-09-09]
   Nyckelord :;

   Sammanfattning : During recent years the palsa mires of Fennoscandia have reported to be undergoing extensive lateral degradation, and in a warming environment the palsa mires of Sweden among others are threatened to thaw completely by the end of this century. Since subarctic peatlands account for 30% of the global soil organic carbon storage, small degradation changes in these areas globally, can potentially change the greenhouse gas emissions on a worldwide scale.

4. 3. Geographical expansion rate of a brown bear population in Fennoscandia and the factors explaining the directional variations

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

   Författare :Lisbet Hougaard Baklid; [2022]
   Nyckelord :Geography; GIS; brown bear; expansion rate; Ursus arctos; Fennoscandia; Sweden; barrier; Earth and Environmental Sciences;

   Sammanfattning : The brown bears, Ursus arctos L., in the Scandinavian peninsula were distributed in almost all counties before aimed reduction during the 1700-1900s (Swenson et al. 1995). From 1981-2013 the population increased more than five times (Chapron et al. LÄS MER

5. 4. The end of the timber frontier in northern Sweden : early logging, natural forests and the frontier concept

   Master-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Alice Cosatti; [2022]
   Nyckelord :timber frontier; Northern Sweden; Tjeggelvas nature reserve; Piteälven; Norrbotten; high-grading;

   Sammanfattning : The Fennoscandian forests experienced drastic changes in the 19th century. The high demand for timber during the European industrialization pushed the timber companies towards increasingly remote forest landscapes for resource extraction. LÄS MER

7. 5. Perspektiv på en bronsålder–koloni vid Norrlandskusten : En studie om kontinuitet och förändring i röse-kulturen

   Kandidat-uppsats, Umeå universitet/Institutionen för idé- och samhällsstudier

   Författare :Magnus Stenius; [2021]
   Nyckelord :Cairns; Settlements; Kiukaisculture; Late-Neolithic; Bronze-Age; territory; maritime;

   Sammanfattning : This essay is focused on two coastal cairn areas located at the Gulf of Bothnia just south of Umeå in Västerbotten County. Located between 30 – 50 m above sea level today they are thus removed several km from the shoreline due to land uplift and isostatic processes stemming from the last Ice Age. LÄS MER
