  4. 2. Accelerator Mass Spectrometry of 36Cl and 129I : Analytical Aspects and Applications

    Author : Vasily Alfimov; Göran Possnert; Ala Aldahan; Hans-Arno Synal; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Accelerator Mass Spectrometry; iodine-129; chlorine-36; gas-filled magnet; radioactive tracer; Arctic Ocean; Nordic Seas; North Atlantic; thermohaline circulation; Sellafield; La Hague; Miljöteknik; Environmental engineering; Miljöteknik;

    Abstract : Two long-lived halogen radionuclides (36Cl, T1/2 = 301 kyr, and 129I, T1/2 = 15.7 Myr) have been studied by means of Accelerator Mass Spectrometry (AMS) at the Uppsala Tandem Laboratory. The 36Cl measurements in natural samples using a medium-sized tandem accelerator (~1 MeV/amu) have been considered. READ MORE

  5. 3. Chemical composition of Arctic aerosols and their link to clouds

    Author : Yvette Gramlich; Claudia Mohr; Paul Zieger; Ilona Riipinen; Ulrich Pöschl; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic; aerosols; cloud residuals; mass spectrometry; biomass burning; Environmental Sciences; miljövetenskap;

    Abstract : The Arctic is a place particularly vulnerable to climate change, warming at an accelerated rate compared to the rest of the Earth. In this remote environment, the atmosphere, the ocean, the ice, and the land are all interlinked and are shaping a very complex system. READ MORE

  6. 4. Atmospheric DMS in the High Arctic

    Author : Jenny Lundén; Gunilla Svensson; Caroline Leck; Leonor Tarrason; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DMS; Modelling; Arctic; Meteorology; Meteorologi; meteorologi; Meteorology;

    Abstract : During the Arctic summer when the anthropogenic influence is limited, the natural marine source of sulfur in the form of gas-phase dimethyl sulfide viz. DMS(g), is of great importance for cloud formation. READ MORE

  7. 5. Towards a changed view on greenhouse gas exchange in the Arctic: new findings and improved techniques

    Author : Mikhail Mastepanov; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; methane; carbon dioxide; greenhouse gas; chamber; Arctic; fen; permafrost;

    Abstract : Arctic ecosystems represent an important component in the global terrestrial exchange of greenhouse gases and energy with the atmosphere. In the changing climate, which is most pronounced in the Arctic, the possible scenarios of greenhouse gas exchange response should be seriously considered in predictive climate modelling efforts.
