  2. 1. Light conditions in seasonally ice-covered waters : within the Baltic Sea region

    Author : Elina Kari; Susanne Kratzer; Matti Leppäranta; Monika Winder; Tiit Kutser; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seasonal sea ice; Fast ice; Drift ice; Phytoplankton spring bloom; Under-ice plume; Turbidity; Suspended particulate matter; Chlorophyll; Coloured dissolved organic matter; Baltic Sea; Marine Ecology; marin ekologi;

    Abstract : Seasonal ice cover is a major driver of seasonality in aquatic ecosystems in the Baltic Sea region. Ice cover influences the underwater light conditions directly by limiting the light transfer and indirectly by modifying the mixing and circulation under the ice. READ MORE

  4. 2. Air-Sea Fluxes of CO2 : Analysis Methods and Impact on Carbon Budget

    Author : Maria Norman; Anna Rutgersson; Erik Sahlée; William Drennan; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; air-sea exchange; carbon dioxide; Baltic Sea; eddy-covariance method; inertial dissipation method; cospectral-peak method; Baltic Sea measurements; CO2 fluxes; Galathea 3 expedition; Baltic Sea modeling; water-side convection; coastal upwelling; carbon budget; Meteorology; Meteorologi;

    Abstract : Carbon dioxide (CO2) is an important greenhouse gas, and the atmospheric concentration of CO2 has increased by more than 100 ppm since prior to the industrial revolution.  The global oceans are considered an important sink of atmospheric CO2, since approximately one third of the anthropogenic emissions are absorbed by the oceans.

  5. 3. Mechanisms controlling air-sea gas exchange in the Baltic Sea

    Author : Lucía Gutiérrez-Loza; Anna Rutgersson; Erik Sahlée; Marcus Wallin; John Prytherch; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Air-sea gas exchange; Baltic Sea; CO2 flux; methane flux;

    Abstract : Carbon plays a major role in physical and biogeochemical processes in the atmosphere, the biosphere, and the ocean. CO2 and CH4 are two of the most common carbon-containing compounds in the atmosphere, also recognized as major greenhouse gases. READ MORE

  6. 4. Networking a region into existence? : dynamics of civil society regionalization in the Baltic Sea Area

    Author : Marta Reuter; Södertörns högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : .... READ MORE

  7. 5. Organic carbon dynamics in the Baltic Sea : A modelling perspective

    Author : Filippa Fransner; Jonas Nycander; Christoph Humborg; Andreas Oschlies; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon cycle; organic carbon; primary production; remineralisation; terrestrial DOC; extracellular DOC; flexible stoichiometry; Redfield ratio; air-sea CO2 exchange; pCO2; coupled 3D physical-biogeochemical modelling; Gulf of Bothnia; Baltic Sea; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Coastal seas constitute a link between land and the open ocean, and therefore play an important role in the global carbon cycle. Large amounts of carbon, of both terrestrial and marine origin, transit and are transformed in these waters, which belong to the more productive areas of the oceans. READ MORE
