  1. 16. CARBONDIOXIDE FLUXES FROM A CONTROLLED BOREAL RIVER

    University essay from Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

    Author : FRANK ARTHUR; [2018]
    Keywords : Carbon dioxide fluxes; Gas transfer Velocity; Turbulence; Eddy covariance; Stream flow; Wind speed; Global Carbon cycle; Latent and sensible heat fluxes.;

    Abstract : River, lakes and   streams account for more carbon dioxide emissions than all other freshwater   reservoirs together. However, there is still lack of knowledge of the   physical processes that control the efficiency of the air-water exchange of   CO2 in these aquatic systems. READ MORE

  3. 17. Dissolved organic carbon (DOC) : Differences in reactivity amongst water sources to boreal streams in Sweden

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Lukas Eriksson; [2018]
    Keywords : Dissolved organic carbon; DOC; Discrete riparian inputs; Resazurin; Resorufin;

    Abstract : The importance of dissolved organic carbon (DOC) to aquatic environments is well established in the scientific community. In boreal landscapes, small streams receive water from headwater lakes, mires, and discrete flow paths that drain riparian soils. READ MORE

  4. 18. Production, sorption and pathways for dissolved organic carbon flow in the Krycklan catchment. : Modelling with focus on the terrestrial forest ecosystem.

    University essay from KTH/Mark- och vattenteknik

    Author : Francisco Mieres Dinamarca; [2016]
    Keywords : Dissolved Organic Carbon; Modelling; Krycklan Catchment;

    Abstract : Dissolved Organic Carbon accounts for many different functions in the boreal forest ecosystem. It is the main vehicle for organic carbon transport from the litterfall to the forest soil profile and together with water drainage it can be transported to streams. READ MORE

  5. 19. Spatial variability of aquatic carbon dioxide and methane concentrations : A study of a hemi-boreal stream

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Hampus Haglund; Daniel Klingmyr; [2016]
    Keywords : Carbon dioxide; methane; spatial variability; greenhouse gases; stream emissions; freshwater carbon dynamics; natural greenhouse gas emissions;

    Abstract : Inland waters such as streams and lakes have recently been found to be supersaturated with both carbon dioxide (CO2) and methane (CH4) – the high concentrations resulting in significant natural emissions of greenhouse gases (GHGs). Previous studies have shown that streams emit particularly large amounts of GHGs per area covered, but the spatial variability is very high and has rarely been studied in detail. READ MORE

  6. 20. Quantification of Terrestrial CO2 Sources to a Headwater Streamin a Boreal Forest Catchment

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Elin Hultin Eriksson; [2016]
    Keywords : Deep soil respiration; headwater streams; lateral CO2 export; CO2 storage; riparian zone; Krycklan; Djup jordrespiration; bäckar; lateral CO2-export; CO2-lagring; riparianzon; Krycklan;

    Abstract : Carbon Dioxide (CO2) emissions from streams are a significant component of the global carbon cycle.Terrestrial export of CO2 through runoff is increasingly recognized as a major source of CO2 in boreal headwater streams. READ MORE
