  1. 11. BVOC emissions from a subarctic mountain birch : analysis of short term chamber measurements

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Erik Ahlberg; [2011]
    Keywords : fjällbjörk; flyktiga kolföreningar; geografi; naturgeografi; BVOC; mountain birch; volatile organic compounds; physical geography; geography; Earth and Environmental Sciences;

    Abstract : Flyktiga organiska föreningar som släpps ut från växter (BVOC- Biogenic volatile organic compounds) kan ha en stor påverkan på atmosfärisk kemi genom reaktioner som leder till ökad eller minskad ozonproduktion, och genom att de kan vara ett förstadium till aerosoler. De vanligaste flyktiga organiska föreningarna är isopren (2-metyl, 1,3-butadien) och dess derivat, terpener och terpenoider (isoprenoider). READ MORE

  3. 12. Estimating soil organic carbon from soils to the sea

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Ana R.A. Saores; [2011]
    Keywords : TOC; DOC; organic carbon; headwater catchments; TOC losses;

    Abstract : Carbon lateral exports from terrestrial soils to the water conduit have been recently recognized as important components of global C budgets. These fluxes play also a major role in several processes within freshwaters that are important for biodiversity and human health. READ MORE

  4. 13. Mud volcanoes : a review

    University essay from Lunds universitet/Geologiska institutionen

    Author : Maria Åkesson; [2008]
    Keywords : mud volcanism; mud volcanoes; methane; climate dynamics; LUSI; Earth and Environmental Sciences;

    Abstract : Mud volcanoes are pathways through and within which buried argillaceous loose sediments and lithified rocks are altered and transported back to the Earth’s surface. The types of mechanisms of formation, maintenance and triggering of this natural, sedimentary recycling-process vary largely whereby external as well as internal properties of mud volcanoes differ greatly.

  5. 14. Snow cover dynamics and plant phenology documentation using digital camera images and their relation with CO2-fluxes at Stordalen mire, northern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Susanne Svensson; [2005]
    Keywords : naturgeografi; climatology; cartography; carbon flux; climate monitoring; physical geography; snowmelt; pedology; geomorphology; geomorfologi; marklära; kartografi; klimatologi; Earth and Environmental Sciences;

    Abstract : This report investigates the utilization of digital camera images (DCIs), sensitive in the visible part of the spectrum, for documentation of seasonal and inter-annual variations in snow cover and plant phenology. The DCIs used were transformed to orthographic images (ortho-image) from ordinary oblique DCIs taken between January 2001 and December 2003 at a sub- arctic mire (Stordalen) in northern Sweden.

  6. 15. Winter dynamics of the greenhouse gas exchange in a natural bog

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Magnus Lund; [2005]
    Keywords : geomorfologi; naturgeografi; climatology; cartography; denitrification; Fäjemyren; physical geography; N2O uptake; pedology; geomorphology; marklära; kartografi; klimatologi; Earth and Environmental Sciences;

    Abstract : Northern peatlands are important in the context of the climate change. Since they comprise huge amounts of soil organic carbon and are found where the most significant greenhouse warming is predicted, they have the potential to exert major feedback effects on the global warming.
