  2. 1. Carbon Dynamics in Northern Marginal Seas

    Author : Sofia Hjalmarsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dissolved inorganic carbon; total alkalinity; continental shelf pump; marginal seas; Baltic Sea; Skagerrak; Laptev Sea; East Siberian Sea; Chukchi Sea;

    Abstract : The marginal seas have, despite their relatively small area, an important role in the global carbon cycle. They are largely influenced by carbon and nutrient fluxes from land and a large part of the biological production occurs in the marginal seas. READ MORE

  4. 2. Ocean circulation in the Amundsen Sea, West Antarctica

    Author : Ola Kalén; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ocean; currents; icebergs; remote sensing; ocean model;

    Abstract : The increase of mass loss from the Antarctic Ice Sheet is a significant contribution to global sea level rise. The most rapid changes are occurring in the Amundsen Sea area, where the thinning of the floating glaciers is assumed to be driven by the ocean. READ MORE

  5. 3. An evaluation of the distributions of polychlorinated biphenyls and organic matter in coastal sediments

    Author : Anders Jönsson; Örjan Gustafsson; Detlef Schulz-Bull; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polychlorinated biphenyls PCBs ; organic carbon; sediment; stable carbon isotopes; Earth sciences; Geovetenskap;

    Abstract : The objective of this thesis is to improve the understanding of what processes and mechanism affects the distribution of polychlorinated biphenyls (PCBs) and organic carbon in coastal sediments. Because of the strong association of hydrophobic organic contaminants (HOCs) such as PCBs with organic matter in the aquatic environment, these two entities are naturally linked. READ MORE

  6. 4. Glacial history of Northeast Greenland: cosmogenic nuclide constraints on chronology and ice dynamics

    Author : Lena Håkanson; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Jameson Land; Store Koldewey; Scoresby Sund; Ice dynamics; Glacial history; Cosmogenic; Greenland Ice Sheet;

    Abstract : The aim of this thesis was to use cosmogenic exposure dating to investigating whether highly weathered landscapes in the Northeast Greenland fjord zone have developed during prolonged ice free conditions or have been preserved beneath cold-based ice. Previous work along the Northeast Greenland coast has presented two conflicting hypotheses for the extent of the Greenland Ice Sheet during the last glacial maximum (LGM). READ MORE

  7. 5. Organic geochemical investigation of sources, transport and fate of terrestrial organic matter in the southeast Laptev Sea

    Author : Emma Karlsson; Örjan Gustafsson; Volker Brüchert; Sebastian Sobek; Rienk Smittenberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biogeochemistry; biogeokemi; Marine Geoscience; marin geovetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Permafrost carbon stores have been suggested to react to warming trends with increased terrestrial loading to its coastal waters. Presently, the warming has been seen to be especially high in the East Siberian Arctic and the fate of the major release of terrestrial matter to these coasts is yet to be detailed. READ MORE
