  1. 11. Arktis, en plats för både soft och hard power?

    Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Ida Molin; [2023]
    Nyckelord :Arktis; Kina; Ryssland; soft power; hard power; Nordostpassagen; Law and Political Science;

    Sammanfattning : The Arctic is a changing place where the melting of the ice creates new opportunities and shipping lanes, such as Northern Sea Route and possibility for raw material extraction. However, this prospects can also be a road to conflict. LÄS MER

  3. 12. Initial Orbit Determination of Resident Space Objects From A Passive Optical Imaging System: : Application to Space Situational Awareness

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Jessica McKenna; [2023]
    Nyckelord :Space Situational Awareness; Space Science; Angles-Only Initial Orbit Determination;

    Sammanfattning : The probability of satellite collisions and disintegrations cluttering the near-Earth orbital environmentis ever-growing. This is especially true for the congested Low Earth Orbit (LEO) regime; once a critical density of objects is reached, a collisional cascading is projected to generate runaway growth of theorbital population.

  4. 13. USA och Norges avskräckningsstrategier i Arktis

    Master-uppsats, Försvarshögskolan

    Författare :Mathias Holmberg; [2023]
    Nyckelord :Arktis; Avskräckning; Militärstrategi; Norge; Regional Security Complex Theory; USA;

    Sammanfattning : This qualitative study explores the application of deterrence strategies by the United States and Norway in the Arctic. Using the Regional Security Complex Theory to understand complex interactions in the region, the study finds that the countries have differing perspectives and strategies. LÄS MER

  5. 14. Evaluating the effects of climate change on Arctic char : including impacts of brown trout competition

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Ola Carlström; [2023]
    Nyckelord :arctic char; brown trout; climate change; diet; habitat use; temperature;

    Sammanfattning : Climate change is predicted to increase the average global temperature with 1.5 °C between 2030 and 2052. The areas that are most vulnerable for climate change are the arctic regions. Arctic char (Salvelinus alpinus) is a cold-water salmonid species with the most northern distribution of all freshwater fish species. LÄS MER

  7. 15. Loess as an Environmental Proxy for Reconstruction of Palaeoclimate in the High Arctic

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Sara Rognås; [2023]
    Nyckelord :aeolian transport; loess; grain size analysis; loss on ignition; palaeoclimate; Svalbard; Holocene; vindtransporterat material; lössjord; kornstorlek; loss on ignition; paleoklimat; Svalbard; Holocen;

    Sammanfattning : We are currently speeding towards significant changes in the climate of the earth which, if ignored, will lead to severely altered climatic conditions with serious consequences for several species and ecosystems. The polar regions especially are very sensitive to climate changes, and the changes these regions undergo affect the climate on a global scale. LÄS MER
