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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Anna Cecilia Nydahl; Gesa A. Weyhenmeyer; Marguerite Xenopoulos; [2019]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  2. 2. Greenhouse gas emission from tropical reservoirs Spatial and temporal dynamics

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Annika Linkhorst; Sebastian Sobek; Frédéric Guérin; [2019]

    Sammanfattning : The emission of methane (CH4) and carbon dioxide (CO2) from reservoirs has been estimated to make up for about 1.3% of the global anthropogenic greenhouse gas emission. The impoundment of a river leads to the accumulation of sediment that is brought in from inflowing rivers, and the sediment organic matter is degraded to CH4 and CO2. LÄS MER

  3. 3. Carbon Emissions from Western Siberian Inland Waters

    Detta är en avhandling från Umeå : Umeå University

    Författare :Svetlana Serikova; Jan Karlsson; Oleg S. Pokrovsky; Hjalmar Laudon; Peter Raymond; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; carbon; carbon dioxide; methane; carbon emissions; river; lake; inland waters; permafrost; Siberia; Limnology; limnologi;

    Sammanfattning : 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. LÄS MER

  4. 4. Arctic Water System Change and its Interactions with Permafrost and Ecosystem Changes

    Detta är en avhandling från Stockholm : Department of Physical Geography and Quaternary Geology, Stockholm University

    Författare :Johanna Mård Karlsson; Georgia Destouni; Daqing Yang; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arctic; climate change; monitoring; ecosystem shifts; hydrology; hydro-climatic change; permafrost; Physical Geography; naturgeografi;

    Sammanfattning : Climate change and various changes in the landscape itself, such as permafrost thaw, may trigger and mediate substantial changes in the inland water system of the Arctic. Many climate change responses in the Arctic landscape and ecosystems are then related to alterations in the hydrological system. LÄS MER

  5. 5. Physical process effects on catchment-scale pollutant transport-attenuation, coastal loading and abatement efficiency

    Detta är en avhandling från Stockholm : KTH

    Författare :Georg Lindgren; Georgia Destouni; Roko Andricevic; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Efficient pollutant load abatement; groundwater-surface water interactions; biogeochemical cycles; nitrogen; Lagrangian stochastic travel time approach; GIS; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Hydrology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Hydrologi;

    Sammanfattning : Pollutants follow various subsurface and surface water pathways from sources within a catchment to its outlet and may cause detrimental effects on downstream water quality and ecosystems. Along their different transport pathways through a catchment, pollutants may be attenuated subject to different physical and biogeochemical processes. LÄS MER
