  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. Tracing the source of colourless carbon in an arctic lake on SW Greenland : Insights of organic matter origin from hydrogen isotope analyses of samples prepared using steam equilibration

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

    Author : Bror Holmgren; [2016]
    Keywords : Søndre Strømfjord; dissolved organic carbon; stable isotopes; steam equilibration;

    Abstract : Lakes play an important role in the global carbon (C) cycle as they process carbon from terrestrial (allochthonous) and within lake (autochthonous) sources and may store C over long periods of time. Some arctic lakes contain high concentrations of dissolved organic carbon (DOC) that does not absorb light and thus remains colourless. READ MORE
