  1. 16. Spatiotemporal variability in methane emission from an Arctic fen over a growing season : dynamics and driving factors

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Kirstine Skov; [2014]
    Keywords : seasonal variability; Arctic wetlands; physical geography; methane emission; biological factors.; geography; ebullition; environmental factors; spatial variability; Earth and Environmental Sciences;

    Abstract : Resume. Metanudledning fra Nordlige vådområder udgør en betydelig del af den naturlige udledning af metan, en potent drivhusgas. Både fysiske og biologiske faktorer influerer produktion, oxidation og transport af metan og dermed netto udledningen. Udledningen af metan fra Nordlige vådområder viser stor rumlig og tidslig variation. READ MORE

  3. 17. Modelling methane emissions from Arctic tundra wetlands : effects of fractional wetland maps

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Zhanzhang Cai; [2014]
    Keywords : fractional wetland maps; Arctic tundra; methane emissions; biogeochemical modelling; Physical Geography and Ecosystem analysis; LPJ-GUESS; sensitivity test; parameter optimization; Earth and Environmental Sciences;

    Abstract : The Arctic tundra has been considered as one of the most sensitive areas to global climate change. One impact of global warming is that permafrost thawing could result in more waterlogged and anaerobic conditions, and consequently an increasing release of methane (CH4) to the atmosphere.

  4. 18. Experimental Tools for Studies of Heterogeneous Catalysis - Development and Case Studies

    University essay from Lunds universitet/Fysiska institutionen

    Author : Jonas Evertsson; [2013]
    Keywords : X-ray Diffraction; PLIF; Planar Laser Induced Fluorescence; activity measurement; reactor; catalyst; catalytic processes; XRD; Mass spectrometry; Heterogeneous catalysis; Chemistry; Physics and Astronomy;

    Abstract : In this project four reactors for studies of heterogeneous catalysis have been developed. They were tested using case studies, especially concerning methane oxidation over palladium. The test measurements showed that the reactors work or would work very well after slight modifications. READ MORE

  5. 19. Observation of methanogenesis and potential iron-dependent anaerobic oxidation of methane in old lake sediments, a study of two boreal forest lakes.

    University essay from Institutionen för biologisk grundutbildning

    Author : Elias Broman; [2013]
    Keywords : Limnology; Lake; Sediment; Methane; Anaerobic oxidation;

    Abstract : Organic and inorganic carbon can enter inland waters in different ways, and often a considerable amount of this carbon is coming from terrestrial input. Once this terrestrial carbon enters a lake, the carbon may be degraded, mineralized or eventually buried in the sediment. READ MORE

  6. 20. Diurnal variation in methane flux in a low-arctic fen in Southwest Greenland

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Bjarne Munk Lyshede; [2012]
    Keywords : geography; physical geography and ecosystem analysis; diurnal; methane; wetland; Arctic; Greenland; Earth and Environmental Sciences;

    Abstract : Popular science: A Day in the Life of a Methane Bog Methane gas is continuously released from wetlands around the world. In Kobbefjord, Greenland the release of methane is low during the cold of winter and higher in warm summer months. But the amount released also varies from day to night; a pattern that has to do with both temperature and light. READ MORE
