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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Anton Thorell; [2023]
    Keywords : 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.;

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Miljövetenskaplig utbildning

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

    Abstract : 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. READ MORE

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

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

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Isabelle Karnik; [2019]
    Keywords : loess; XRF; weathering index; Holocene climate; Greenland;

    Abstract : 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. READ MORE

  6. 5. Analysis of Arctic peak-season carbon flux estimations based on four MODIS vegetation products

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Antonin Kusbach; [2016]
    Keywords : satellite-derived data; vegetation indices; Arctic; net ecosystem exchange; big data analysis; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

    Abstract : Increased temperatures in high latitudes may alter the carbon dynamics throughout the Arctic. Modelled CO2 simulations show that current climate conditions constitute the Arctic a net carbon sink, though the large extent and fine landscape heterogeneity raise an uncertainty about the carbon sink/source status of the region.
