  1. 1. Methods for measuring mercury in gas ebullition from fiber banks : A literature study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Diana Jonsson; [2021]
    Keywords : Fiber bank; fiber rich-sediment; mercury; contaminants; gas ebullition; pulp-fiber; wood industry; paper industry; environmental toxicity; wood waste;

    Abstract : Mercury contamination is an environmental issue with high priority due to its high toxicity. In addition to the atmospheric deposition, several lakes and rivers in Sweden are contaminated as a result from wood and pulp-fiber industries which stretches back 200 years. READ MORE

  3. 2. Traits of peat- and upland-derived stream dissolved organic carbon in the permafrost region around Abisko, northern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nora Kainz; [2021]
    Keywords : physical geography; ecosystem analysis; permafrost degradation; DOC; DOC concentration; stable isotope carbon signature; DOC quality; DOC degradation; Atmospheric Sciences and Biogeochemical Cycles; Earth and Environmental Sciences;

    Abstract : Climate change-induced thawing of permafrost mobilizes previously frozen carbon of high potential reactivity, thereby, fuelling microbiological production of greenhouse gases. For this work, an analysis of the quantity, quality, and bioreactivity of DOC in streams from the Stordalen discontinuous permafrost catchment was carried out with stream water samples during the relatively warm summer of 2018.

  4. 3. 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

  5. 4. Importance of large scale extreme precipitation to the surface mass balance of the Greenland Ice sheet

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : Moa Hallberg; [2018]
    Keywords : Ice sheet; Greenland; surface mass balance; atmospheric rivers; Physics and Astronomy;

    Abstract : The ongoing climate change has affected Greenland's ice sheet with heighten near surface temperatures, an extended melt season and change in precipitation. These effects have caused Greenland's ice sheet to melt at an accelerating rate. READ MORE

  6. 5. Natural capital and sustainable development: The story so far

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Falco Richardson; [2016]
    Keywords : economics; economic value; environmental conservation; natural capital; sustainable development; political-ecology;

    Abstract : Natural capital is a way of conceptualizing the linkages between economics and the environment. The concepts foundations can be traced back to the environmental movement of the 1970s and the works of influential economists at that time. READ MORE
