  4. 2. Terrestrial organic carbon dynamics in Arctic coastal areas : budgets and multiple stable isotope approaches

    Author : Vanja Alling; Christoph Humborg; Carl-Magnus Mörth; Rüdiger Stein; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic carbon; DOC; POC; multiple stable isotopes; Laptev Sea; East Siberian Sea; Lena River; Arctic; residence times; degradation; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Arctic rivers transport 31-42 Tg organic carbon (OC) each year to the Arctic Ocean, which is equal to 10% of the global riverine OC discharge. Since the Arctic Ocean only holds approximately 1% of the global ocean volume, the influence of terrestrially derived organic carbon (OCter) in the Arctic Ocean is relatively high. READ MORE

  5. 3. Dissolved and suspended transport of tungsten, molybdenum, and vanadium in natural waters

    Author : Susanne Bauer; Johan Ingri; Carl-Magnus Mörth; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tungsten; molybdenum; vanadium; Baltic Sea; redox cycling; suspended particles; boreal rivers; Applied Geology; Tillämpad geologi;

    Abstract : Some transition metals and metalloids occur primarily as oxyanions in natural waters including antimony, arsenic, chromium, molybdenum, tungsten and vanadium. These oxyanions can pass through cell walls along the same pathways as phosphate or sulfate. Some of these oxyanions are essential for life, but in high concentrations they become all toxic.

    Abstract : The transport of elements by streams from headwater regions to the sea is influenced by landscape characteristics. This thesis focuses on the influence of landscape characteristics (e.g. READ MORE

  7. 5. The influence by point sources on carbon, nitrogen and metals in two sedimentary environments

    Author : Hanna Bohlin; Nils Holm; Carl-Magnus Mörth; Gunnar Jacks; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap;

    Abstract : Sediments in two aquatic environments have been investigated. Both are anthropogenically affected and polluted. The focus has been on stable carbon and nitrogen isotopes, C/N ratios, and heavy metals. The first site is Höggarnsfjärden Bay in the inner parts of the Stockholm Archipelago, Sweden, where a garbage dump releases treated leach water. READ MORE
