  1. 1. Mass Balance of the High-Arctic Glacier Nordenskiöldbreen, Svalbard, in a Changing Climate

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

    Författare :Maja Gustavsson; [2019]
    Nyckelord :Mass balance; glacier; Nordenskiöldbreen; climate change; Massbalans; glaciär; Nordenskiöldbreen; klimatförändringar;

    Sammanfattning : Melting glaciers are the major contributor to sea level rise. Glaciers are sensitive indicators of climate change and current experience strong developments in a rapidly warming Arctic environment. LÄS MER

  2. 2. Spatial and Temporal Variations in a Perennial Firn Aquifer on Lomonosovfonna, Svalbard

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper; Uppsala universitet/Institutionen för geovetenskaper

    Författare :Monika Hawrylak; Emma Nilsson; [2019]
    Nyckelord :perennial firn aquifer; ground penetrating radar; Svalbard; Lomonosovfonna; flerårig firnakvifer; georadar; Svalbard; Lomonosovfonna;

    Sammanfattning : A firn aquifer is a type of englacial water storage that forms when surface meltwater fills up the pore space in porous firn. If the retention time exceeds one year the feature is regarded as perennial. The melt and accumulation rates as well as the available pore space determine the formation and extent of the firn aquifer. LÄS MER

  3. 3. On the Relationship Between Energetic Electron Precipitation and Mesopause Temperature

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

    Författare :Florine Enengl; [2019]
    Nyckelord :;

    Sammanfattning : Energetic Particle Precipitation (EPP) can potentially change the neutral atmospheric temperatureat the mesopause region. Cresswell-Moorcock et al. (2013) used European IncoherentScatter Scientific Association (EISCAT) radar data to identify strong electron precipitationevents. LÄS MER

  4. 4. A Regional Analysis of Changing Climate Conditions and Glacier Mass Balance in Svalbard

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Ottar Bergman; [2019]
    Nyckelord :glacier mass balance; model data; climate change; Svalbard;

    Sammanfattning : The Arctic archipelago of Svalbard has experienced among the greatest increases in temperature on Earth in the last few decades. The changing climatic conditions have a large impact on the glacier mass balance. This study makes use of a highresolution model dataset with data on climatic and glacier conditions on Svalbard from 1957 to 2018. LÄS MER

  5. 5. A detailed study of auroral fragments

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomiUppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Författare :Joshua Dreyer; [2019]
    Nyckelord :aurora; fragments; Svalbard; all-sky camera; MSP; ASK; EISCAT;

    Sammanfattning : Aurora occurs in various shapes, one of which is the hitherto unreported phenomenon of auroral fragments. For three periods of occurrence of these fragments their properties were studied in detail during this master’s thesis, using mainly ground-based instrumentation located near Longyearbyen on Svalbard, Norway.
