  1. 21. Mineralogical and Geochemical Study of Acid Mine Drainage from 100 Years of Coal Mining in Svalbard (78° N)

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Andreas Rehn; [2020]
    Keywords : Acid rock drainage; Acid mine drainage; coal mine waste; Pyrite; Arctic; Svalbard; Spitzbergen;

    Abstract : Waste rock piles from coal mining of tertiary bituminous coal in Longyearbyen, Svalbard, show sulfide oxidation and subsequent acid mine drainage (AMD) production. The aim was to establish deeper understanding of AMD prediction based on Mineralogy and Geochemistry of coal and AMD samples. READ MORE

  3. 22. Effects of snow-free season, temperature and radiation variations on the retreat of Linné glacier, Svalbard

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Juliano Hanna; [2020]
    Keywords : Glacier; Arctic; Svalbard; climate change; GIS; drone; air temperature and solar radiation; Earth and Environmental Sciences;

    Abstract : Linné glacier has retreated approximately 1.8 km since 1936 and 1 km between 1995 and 2019. Linné glacier is following the same trend as other glaciers around Svalbard. Linné glacier is a well-monitored glacier with a time series of air temperature, incoming solar radiation and snow height data since 2003. READ MORE

  4. 23. Movement of Foxfonna rock glacier in Svalbard between 2017-2019

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Elias Lundström; [2020]
    Keywords : rock glacier; Svalbard; UAV; photogrammetry; movement detection; permafrost; Earth and Environmental Sciences;

    Abstract : The movement of a rock glacier located at the bottom of the Foxfonna glacier, Svalbard, Norway, was studied through the use of photogrammetry and feature tracking software, between the years of 2017-2019, as well as elevation changes between 2009 and 2019. This could aid in further knowledge about the rapid velocity changes of rock glaciers in a continuous permafrost environment. READ MORE

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

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

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

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE
