  1. 1. 231Pa and Th isotopes as tracers of deep water ventilation and scavenging in the Mediterranean Sea

    Författare :Sandra Gdaniec; Carl-MAgnus Mörth; Per Andersson; Helen Coxall; Per Roos; Per Anerson; Matthieu Roy-Barman; Carl-Magnus Mörth; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; 231Pa; 230Th; 232Th; Mediterranean Sea; scavenging; deep water ventilation; geokemi; Geochemistry; Protactinium; Thorium; particle transport; deep water circulation;

    Sammanfattning : The naturally occurring isotopes 231Pa and 230Th are used as tracers of marine biogeochemical processes. They are both produced from the radioactive decay of their uniformly distributed uranium parents (235U and 234U) in seawater. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 5. Landscape hydrogeochemistry of Fe, Mn, S and trace elements (As, Co, Pb) in a boreal stream network

    Författare :Louise Björkvald; Carl-Magnus Mörth; Hjalmar Laudon; Christine Alewell; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; landscape hydrogeochemistry; boreal streams; spring flood; Fe; Mn; S; As; Co; Pb; sulphur isotopes; sulphate; organic S; DOC; spatial variability; temporal variability; wetlands; Earth sciences; Geovetenskap; geokemi; Geochemistry;

    Sammanfattning : 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. LÄS MER
