  1. 1. Carbon Dioxide in Inland Waters Drivers and Mechanisms Across Spatial and Temporal Scales

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Cecilia Nydahl; Uppsala universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon dioxide; dissolved organic carbon; inland water; lake; stream; groundwater; mesocosm; carbonate system; carbon; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Inland waters are an essential component of the global carbon cycle as they are very active sites for carbon transformation processes. Much of this carbon is transformed into the greenhouse gas carbon dioxide (CO2) and emitted into the atmosphere. READ MORE

  2. 2. Carbon Emissions from Western Siberian Inland Waters

    University dissertation from Umeå : Umeå University

    Author : Svetlana Serikova; Umeå universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; carbon; carbon dioxide; methane; carbon emissions; river; lake; inland waters; permafrost; Siberia; Limnology; limnologi;

    Abstract : Inland waters (i.e. rivers, streams, lakes, ponds) emit carbon (C) into the atmosphere. The magnitude of global inland water C emission has been estimated to equal the global ocean C sink, thus making inland waters an important component of the global C cycle. READ MORE

  3. 3. Organic carbon dynamics in the Baltic Sea A modelling perspective

    University dissertation from Stockholm : Department of Meteorology, Stockholm University

    Author : Filippa Fransner; Stockholms universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon cycle; organic carbon; primary production; remineralisation; terrestrial DOC; extracellular DOC; flexible stoichiometry; Redfield ratio; air-sea CO2 exchange; pCO2; coupled 3D physical-biogeochemical modelling; Gulf of Bothnia; Baltic Sea; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Abstract : Coastal seas constitute a link between land and the open ocean, and therefore play an important role in the global carbon cycle. Large amounts of carbon, of both terrestrial and marine origin, transit and are transformed in these waters, which belong to the more productive areas of the oceans. READ MORE

  4. 4. Flocculation of Allochthonous Dissolved Organic Matter – a Significant Pathway of Sedimentation and Carbon Burial in Lakes

    University dissertation from Uppsala : Universitetsbiblioteket

    Author : Eddie von Wachenfeldt; Uppsala universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; flocculation; dissolved organic carbon; allochthonous; carbon sequestration; carbon cycle; boreal lakes; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Freshwater ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi Limnisk ekologi;

    Abstract : Inland waters receive substantial amounts of organic carbon from adjacent watersheds. Only about half of the carbon exported from inland waters reaches the oceans, while the remainder is lost en route. This thesis identifies flocculation as an important and significant fate of carbon in the boreal landscape. READ MORE

  5. 5. Waterborne Carbon in Northern Streams Controls on dissolved carbon transport across sub-arctic Scandinavia

    University dissertation from Stockholm : Department of Physical Geography, Stockholms Universitet

    Author : Elin Jantze; Stockholms universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dissolved carbon; DOC; DIC; TOC; sub-arctic; hydrology; Abisko; Physical Geography; naturgeografi;

    Abstract : Waterborne carbon (C) forms an active and significant part of the global C cycle, which is important in theArctic where greater temperature increases and variability are anticipated relative to the rest of the globe withpotential implications for the C cycle. Understanding and quantification of the current processes governing themovement of C by connecting terrestrial and marine systems is necessary to better estimate future changes ofwaterborne C.
