  1. 1. Flotation of Yxsjöberg historical tungsten ore tailings

    Master-uppsats, Luleå tekniska universitet/Mineralteknik och metallurgi

    Författare :Princess Rochelle Gan; [2019]
    Nyckelord :;

    Sammanfattning : Tailings dams, due to their sheer size and metal content, pose safety and environmental hazards. The Småltjarnen repository, which hosts material from the largest known tungsten mineralization in Sweden named the Yxsjöberg deposit, is estimated to contain 2. LÄS MER

  2. 2. Cold Surface Layer Dynamics of Storglaciären, Northern Sweden 2009-2019

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Shunan Feng; [2019]
    Nyckelord :Storglaciären; cold surface layer; cold-temperate transition surface; polythermal glacier; Storglaciären; kallt ytskikt; kall-tempererad is; polyterrmal glaciär;

    Sammanfattning : Storglaciären is a sub-Arctic polythermal glacier in northern Sweden. Twenty years' monitoring of thecold surface layer found that it has lost one third of its total volume of cold ice with an average thinningrate of 0.80 ± 0.24 m·a-1 for the period of 1989-2009. LÄS MER

  3. 3. Impact of different atmospheric forcings on surface mass balance estimates in Greenland

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Stina Olandersson; [2018]
    Nyckelord :Physical Geography and Ecosystem analysis; surface mass balance; Greenland; climate models; numerical weather prediction models; surface energy balance; Arctic; climate change; Earth and Environmental Sciences;

    Sammanfattning : The Greenland Ice sheet (GIS) is the second largest ice sheet on Earth and thus stores a large amount of Earths freshwater. Because of climate change and the Arctic amplification, GIS is experiencing changes and increased melt rates. The total mass budget determines the amount of sea level rise caused by input from freshwater from the GIS. LÄS MER

  4. 4. Climate Change and Precipitation Variability Influence on the Greenland Ice Sheet

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Jennie Olsson; [2018]
    Nyckelord :Physics; Ice Sheet; Surface Mass Balance; SMB; Representative Concentration Pathways; RCP; Climate Change; Greenland; Precipitation; Precipitation Variability; Glaciers; Glacier; Meteorology; Greenhouse Effect; Greenhouse Gas; Future Climate; Climate; Physics and Astronomy;

    Sammanfattning : Climate changes have a large impact on precipitation patterns and precipitation variability change. With this in mind, precipitation over Greenland is studied. This is done for present day precipitation model data from 1991-2010 compared to future model simulations of precipitation for 2081-2100. LÄS MER

  5. 5. Increased leaching of metals as a result of foundation work

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Emmy Mattisson; [2018]
    Nyckelord :Principal components analysis; Modified double mass analysis; Geochemistry; Sulphide bedrock; Remediation methods; Surface water pollution;

    Sammanfattning : Heavy metal contamination in the environment is a global issue that is likely to increase in the future. This report investigates a construction area in which increased concentrations of the heavy metals cadmium, cobalt, copper, nickel and zinc and a decreased pH-value has been observed in the surface water recipient.
