  1. 16. Climatic effects of changes in radiative forcing due to clear-cutting in Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Iris Muzic; [2019]
    Keywords : Physical Geography and Ecosystem Science; land-cover change; ICOS; albedo; carbon dioxide; radiative forcing; clear-cutting; Earth and Environmental Sciences;

    Abstract : Land cover conversion affects climate by imposing changes in the surface properties and carbon dioxide fluxes. Forest management programs often disregard that modification in surface albedo influences the exchange of energy and climate sensitivity. READ MORE

  3. 17. 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

  4. 18. Variability and regulation of the planktonic respiratory quotient in a eutrophic lake (Lake Vombsjön) in summer 2016

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Karla Münzner; [2017]
    Keywords : Physical geography and ecosystem analysis; biogeochemistry; bacterioplankton respiration; eutrophic lake; carbon cycling; Lake Vombsjön; Earth and Environmental Sciences;

    Abstract : Bacterial respiration and biomass growth are important processes for carbon cycling in freshwater ecosystems and bacterial respiration is often quantified from measured O2 concentrations by using a respiratory quotient (RQ=O2 consumed to produce CO2, in moles) of 1. Recent studies have shown, however, that RQs can vary a lot in different aquatic ecosystems (0. READ MORE

  5. 19. The effect of tropical cyclones on the carbon cycle

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Brendan Bos; [2017]
    Keywords : Earth and Environmental Sciences;

    Abstract : Tropical cyclones influence processes within the carbon cycle on different time-scales. Forested ecosystems suffer windfall and long-term impacts from tropical cyclones, leading to the release of CO2 to the atmosphere. READ MORE

  6. 20. Organogena jordar : hur man kan minska markytesänkning och växthusgasemission

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Fredrik Karlsson; [2017]
    Keywords : organogena jordar; markytesänkning; mulljord; emission;

    Abstract : Odlade organogena jordar motsvarar idag ca 7 % av den svenska jordbruksmarken. Genom dränering av tidigare våtmarker har de gått från att ackumulera kol till att släppa ut kol i form av koldioxid. READ MORE
