  1. 1. Carbon Dynamics in Northern Marginal Seas

    Author : Sofia Hjalmarsson; Göteborgs universitet.; Gothenburg University.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dissolved inorganic carbon; total alkalinity; continental shelf pump; marginal seas; Baltic Sea; Skagerrak; Laptev Sea; East Siberian Sea; Chukchi Sea;

    Abstract : The marginal seas have, despite their relatively small area, an important role in the global carbon cycle. They are largely influenced by carbon and nutrient fluxes from land and a large part of the biological production occurs in the marginal seas. READ MORE

  2. 2. Transport, degradation and burial of organic matter released from permafrost to the East Siberian Arctic Shelf

    University dissertation from Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Author : Lisa-Marie Bröder; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic carbon; marine sediments; East Siberian Sea; Laptev Sea; cross-shelf transport; degradation rate constants; carbon isotopes; terrestrial biomarkers; HMW wax lipids; lignin phenols; compound-specific radiocarbon analysis; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Permafrost soils in the Arctic store large quantities of organic matter, roughly twice the amount of carbon that was present in the atmosphere before the industrial revolution. This freeze-locked carbon pool is susceptible to thawing caused by amplified global warming at high latitudes. READ MORE

  3. 3. Compositional clues to sources and sinks of terrestrial organic matter transported to the Eurasian Arctic shelf

    University dissertation from Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Author : Emma Karlsson; Stockholms universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic carbon; degradation; microcosm; incubation; terrestrial biomarkers; acyl lipids; lignin phenols; radiocarbon; Eurasian Arctic shelf; East Siberian Sea; Laptev Sea; Lena River; colloidal matter; particulate matter; sedimentary matter; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The amount of organic carbon (OC) present in Siberian Arctic permafrost soils is estimated at twice the amount of carbon currently in the atmosphere. The shelf seas of the Arctic Ocean receive large amounts of this terrestrial OC from Eurasian Arctic rivers and from coastal erosion. READ MORE

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

    University dissertation from Stockholm : Department of Applied Environmental Science (ITM)

    Author : Vanja Alling; Stockholms universitet.; [2010]
    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. 5. Molecular and isotopic characterization of terrestrial organic carbon released to (sub-)Arctic coastal waters

    University dissertation from Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Author : Jorien Elisabeth Vonk; Stockholms universitet.; [2010]
    Keywords : organic carbon; terrestrial biomarkers; radiocarbon; particulate organic carbon; sediments; sphagnum; Arctic; Bothnian Bay; East Siberian Sea; Kalix River; Kolyma River; tillämpad miljövetenskap; Applied Environmental Science;

    Abstract : Arctic soils store half of the global soil organic carbon (OC) pool and twice as much C as is currently present in the atmosphere. A considerable part of these carbon pools are stored in permafrost. READ MORE
