  1. 1. The evaluation of preparation techniques for the measurements of hydrogen isotope ratios in ecology

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

    Author : Kusal Weragama; [2021]
    Keywords : Deuterium; liquid water equilibration; steam equilibration; exchangeable H fraction; non-exchangeable H; Equilibrium fractionation factor; Isotopic soil fraction;

    Abstract : The stable isotope ratio of non-exchangeable hydrogen (δ2Hn) emerged as a promising new tool for source attribution in aquatic ecology, which can better discriminate between the organic matter sources. However, determining the absolute isotopic values is problematic due to the functional groups with hydrogen (H) that can easily exchange with the ambient water. READ MORE

  3. 2. The role of catchment scale for determining hydrological flow paths during spring flood

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Viktor Sjöblom; [2005]
    Keywords : melt water; flow paths; stream flow generation; soil frost; wetlands; 18O; isotopic hydrograph separation;

    Abstract : The purpose of this study was to explore the pathways of melt water during the spring flood. Snow melt is a complex process of great importance for boreal ecosystems, and there are major challenges remaining to fully understand the stream flow generation. The study was carried out at Vindeln Experimental Forests, Vindeln in northern Sweden. READ MORE
