  1. 1. Sporadic-E layers in the polar cap ionosphere : A review on Es occurrence, dynamics and formation theory

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Anton Thorell; [2023]
    Nyckelord :Sporadic-E layers; plasma physics; space physics; arctic geophysics; radar technology; UNIS; Svalbard; EISCAT.; Sporadiska E-skikt; plasmafysik; rymdfysik; arktisk geofysik; radarteknik; UNIS; Svalbard; EISCAT.;

    Sammanfattning : Sporadic-E layers (Es) are layers of metallic ions that appear in the lower E-region of the ionosphere and can last from under one hour to several hours. Es are found at all latitudes, but polar cap Es, and specifically over Svalbard at a latitude of around 78◦ , are the focus of this study. LÄS MER

  3. 2. Feedback effects in the Arctic region and how they affect the global climate

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Lotta Nyman; [2020]
    Nyckelord :Arctic warming; Arctic change; Climate feedback effect; Lower latitude weather; Arctic amplification; Permafrost; Earth and Environmental Sciences;

    Sammanfattning : The Arctic is warming at a rate two to three times that of the global average. Although only covering a small area of the globe, it is a vital component of the climate system. Through climatic feedback effects the warming is enhanced, and risks leading to further climate change. LÄS MER

  4. 3. Den arktiska dragningskraften : En studie om arktisk turism i Norrbotten

    M1-uppsats, Umeå universitet/Institutionen för geografi

    Författare :Karin Lindblad; [2020]
    Nyckelord :Arctic; Tourism; Resources; Norrbotten; Nature;

    Sammanfattning : The view of the world is changing and with it the people’s conception of the magnitude of the world. The reason for this is tourism, never has it been so easy to travel and discover new places. The Arctic, that was once considered a remote and distant place is not anymore. LÄS MER

  5. 4. Tourism in Norrbotten, Sweden : A better understanding of tourism and its future – from the organizations perspective

    Kandidat-uppsats, Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Författare :Rebecca Öhman; Karin Sandlund; [2020]
    Nyckelord :Tourism industry; overcrowding; arctic region; turism industrin; överbefolkat; arktisk region;

    Sammanfattning : The tourism industry is one of the fastest growing industries in the world and the growth of tourism in the northernmost county of Sweden, Norrbotten, has been evident in recent years. With this rapid growth within tourism in Norrbotten, a reflection arises of why tourism is increasing to this extent. LÄS MER

  7. 5. Arctic Loess as an Environmental Archive : Identifying Weathering with XRF Analysis in West Greenland

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Isabelle Karnik; [2019]
    Nyckelord :loess; XRF; weathering index; Holocene climate; Greenland;

    Sammanfattning : Loess from west Greenland was studied to evaluate Holocene paleoclimate in the Arctic region. Deposits of loess are formed over long time scales through deposition of fine aeolian sediment and they exist in several places in the world. LÄS MER
