  2. 21. Dissolved organic carbon in tropical watersheds : Linking field observation and eco-hydrological modelling

    Author : Fabien Rizinjirabake; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dissolved organic carbon DOC ; Rwanda; Land use land cover variability; Climate variability and change; Rukarara River Watershed; eco-hydrological modelling; field observation;

    Abstract : Dissolved organic carbon (DOC) is a general description of the organic material dissolved in water. DOC is an important source of energy, carbon, and nutrient transfers from terrestrial to aquatic ecosystems. The export of DOC into aquatic ecosystems may contribute to the carbon balance of terrestrial ecosystems and to water degradation. READ MORE

  4. 22. Dissolved Organic Matter from a colloidal perspective

    Author : Erika Andersson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dissolved organic matter; colloids; Microbial decomposition; hematite nanoparticles; soil; small angle scattering; light scattering; 1H NMR;

    Abstract : Dissolved organic matter (DOM) is considered the most bioavailable fraction of soil, and thus play a key role in the cycling of carbon. Because of its mobility, DOM also forms the connection between terrestrial and aquatic systems, and constitutes an important vector for nutrients and contaminants. READ MORE

  5. 23. Characterisation of natural dissolved organic matter with liquid chromatography and high resolution mass spectrometry

    Author : Claudia Patriarca; Jonas Bergquist; Lars Tranvik; Per J.R. Sjöberg; Jeffrey A. Hawkes; Norbert Hertkorn; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aquatic carbon cycle; dissolved organic matter; DOM; high resolution mass spectrometry; online liquid chromatography; organic matter characterization; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Abstract : Dissolved organic matter (DOM) is one of the most heterogeneous and complex mixture on Earth. DOM plays a crucial role in biogeochemical processes on the global scale and it is essential to sustain and regulate the biological processes in aquatic ecosystems. READ MORE

  6. 24. Characterization of dissolved organic matter : An analytical challenge

    Author : Claudia Patriarca; Jonas Bergquist; Lars Tranvik; Jeffrey A. Hawkes; Jonathan Martin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Abstract : Dissolved organic matter (DOM) is the prevalent form of organic carbon in most aquatic environments. It is an ultra-complex mixture that plays a crucial role in global carbon cycling. Despite its importance it is still poorly understood due to its extreme heterogeneity and intricacy. READ MORE

  7. 25. Reactive dissolved organic carbon dynamics in a changing environment : Experimental evidence from soil and water

    Author : Balathandayuthabani Panneer Selvam; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dissolved organic carbon; DOC; Photodegradation; Biodegradation; DOC reactivity;

    Abstract : Dissolved organic carbon (DOC) is the major form of organic carbon in aquatic ecosystems. Biological and photochemical degradation of DOC are major causes of greenhouse gas emissions from aquatic ecosystems. READ MORE
