  1. 1. Environmental change during the Holocene : A comparative multi-proxy study of landscape disturbances in Northern Sweden

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Mégane Capel; [2019]
    Keywords : Holocene; Lake-Water TOC; climate; lake sediment; vegetation;

    Abstract : Varved lake sediments were used to provide information on how a landscape is affected by disturbances of different scales, from global (i.e. climatic) to local (i.e. READ MORE

  2. 2. Long-term trends in bottom water chemistry of Swedish lakes

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Jelena Rakovic; [2017]
    Keywords : hypolimnion; sediment; oxygen; dissolved organic carbon; phosphorus; ammonium; silica;

    Abstract : Long-term monitoring of lake water is essential for tracking local and long-range effects of anthro-pogenic pressure and to inform policy aiming at mitigating human environmental impacts. Swedish reference lakes are recovering from acidification; are subject to climate change and increasing inputs of terrestrial dissolved organic matter (DOM). READ MORE

  3. 3. Effect of historical land-use on lake-water carbon and geochemistry: : A multi-proxy study of two lake sediment profiles in Dalarna throughout the Holocene

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Florian Muthreich; [2016]
    Keywords : lake-water TOC; summer farming; forest grazing; sediment geochemistry;

    Abstract : This study examines changes in lake-water total organic carbon (LW-TOC) and lake sediment geochemistry in two lakes, Stångtjärnen and Holtjärnen in (Dalarna, Sweden), during the Holocene and the role of the historic forest grazing and farming (fäbod-system). The aims of the study were to: 1. READ MORE

  4. 4. Tracing late Holocene changes in lake-water total organic carbon : A multi-proxy approach based on sediment bio-geochemistry and a faecal biomarker

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Sofia Jonsson; [2015]
    Keywords : lake-water TOC; faecal biomarkers; Pyrolysis GC MS; forest grazing;

    Abstract : Long-term dynamics of lake-water total organic carbon (LW-TOC) concentrations in freshwater lakes provide an important perspective on the recent increases in LW-TOC observed in many of these systems and may assist with the identification of natural and anthropogenic drivers of change. This study examines how LW-TOC in Dragsjön, a lake situated in an area with a long history of anthropogenic land use, has changed in response to natural and anthropogenic perturbations throughout the Holocene.

  5. 5. Geokemisk undersökning vid Rävlidmyrgruvan, Västerbottens län : provtagning, analys och förslag till åtgärder

    University essay from SLU/Dept. of Soil Sciences

    Author : Sara Frandsen; [2007]
    Keywords : Acid Mine Drainage AMD ; sulfatreducerande bakterier SRB ; sulfidmineral; dagbrottssjö;

    Abstract : The mining industry, in terms of ore excavation and metal production, is and has been important to the Swedish economy. In connection with the ore excavation process, large amounts of partly sulphidic waste are produced. READ MORE
