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

    Author : Anna Cecilia Nydahl; Gesa A. Weyhenmeyer; Marguerite Xenopoulos; Uppsala universitet; []
    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

  4. 2. Carbon Emissions from Western Siberian Inland Waters

    Author : Svetlana Serikova; Jan Karlsson; Oleg S. Pokrovsky; Hjalmar Laudon; Peter Raymond; Umeå universitet; []
    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

  5. 3. Biophysical controls on CO2 evasion from Arctic inland waters

    Author : Gerard Rocher-Ros; Reiner Giesler; Ryan A. Sponseller; Ann-Kristin Bergström; Paul del Giorgio; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Inland waters; carbon dioxide; organic carbon; inorganic carbon; arctic; CO2 evasion; DOC; DIC; streams; metabolism; oxygen; Limnology; limnologi;

    Abstract : CO2 evasion to the atmosphere from inland waters is a major component of the global carbon (C) cycle. Yet spatial patterns of CO2 evasion and the sources of C that fuel evasion remain poorly understood. READ MORE

  6. 4. Monitoring Water Availability in Northern Inland Waters from Space

    Author : Saeid Aminjafari; Fernando Jaramillo; Ian Brown; Cathleen Jones; Stockholms universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Water occurrence; Lake water level; Remote sensing; Altimetry; D-InSAR; naturgeografi; Physical Geography;

    Abstract : River deltas and lakes support biodiversity and offer crucial ecosystem services such as freshwater provision, flood control, and fishing. However, climate change and human activities have affected deltas and lakes globally, altering the services they provide. READ MORE

  7. 5. Land use effects on greenhouse gas emissions from boreal inland waters

    Author : Marcus Klaus; Jan Karlsson; Peter Staehr; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; greenhouse gas; boreal forest; carbon cycling; whole-ecosystem experiment; limnology; metabolism; forest clearcutting; nitrogen enrichment;

    Abstract : Anthropogenic activities perturb the global carbon and nitrogen cycle with large implications for the earth’s climate. Land use activities deliver excess carbon and nitrogen to aquatic ecosystems. In the boreal biome, this is mainly due to forestry and atmospheric deposition. READ MORE
