  1. 1. Changes in lake-water organic carbon over recent centuries in northern Sweden, Västerbotten : Past and present mechanisms, and the potential implications on mercury

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

    Author : Magnusson Petter; [2023]
    Keywords : Lake-water TOC; Summer forest farming; traditional agriculture; land-use; geochemistry; mercury;

    Abstract : Due to the current increase in lake water total organic carbon (LW-TOC), many studies have investigated the long-term dynamics using lake sediments. However, these have mainly been focused on Sweden’s south and south-central parts. READ MORE

  3. 2. Modelling the Effects of Climate Change on Future DOC Export to Lake Mälaren Using a Generalized Watershed Loading Functions (GWLF) Model

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Klara Lindqvist; [2022]
    Keywords : Hydrology; DOC; browning; climate change; drinking water production; Mälaren; Hydrologi; DOC; brunifiering; klimatförändringar; dricksvattenproduktion; Mälaren;

    Abstract : Browning of boreal freshwaters due to an increased export of terrestrial dissolved organic carbon (DOC) has been observed for some decennia. Drivers include recovery from acid deposition and changing climate and land cover. READ MORE

  4. 3. 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

  5. 4. 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

  6. 5. 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
