  2. 16. Mineralisation rates of natural organic matter in surface sediments affected by physical forces

    Author : Carina Ståhlberg; Bo Svensson; Lars Rahm; David Bastviken; Anders Tengberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sediment; Organic matter mineralisation; Organic matter degradation; Redox; Electron acceptor; Resuspension; Advective pore water flow; Other chemistry; Övrig kemi;

    Abstract : Nedbrytning av organiskt material är en nyckelfaktor som påverkar omvandlingar av de många grundämnen som utgör eller är associerade till just organiskt material. En stor del av nedbrytningen av akvatiskt organiskt material (OM) sker i gränsskiktet mellan sediment och vatten. READ MORE

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

    Author : Eddie von Wachenfeldt; Lars Tranvik; David Bastviken; John Downing; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; flocculation; dissolved organic carbon; allochthonous; carbon sequestration; carbon cycle; boreal lakes; Freshwater ecology; 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. 18. Production and emission of CO2 in two unproductive lakes in northern Sweden

    Author : Jan Åberg; Mats Jansson; Anders Jonsson; David Bastviken; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; lake; carbon dioxide; organic carbon; inorganic carbon; boreal; arctic; DOC; DIC; CO2; emission; thermal stratification; allochthonous organic carbon; Freshwater ecology; Limnisk ekologi; Physical geography; Naturgeografi; naturgeografi; Physical Geography;

    Abstract : Unproductive lakes are one of few natural landscape compartments with net release of carbon to the atmosphere. Lakes also generally decrease the net terrestrial carbon uptake, since most of the CO2 production in unproductive lakes are derived from organic carbon produced on land (e.g. in forests). READ MORE
