  1. 11. Oceanographic studies of the Baltic Sea with emphasis on sea ice and mixing processes

    Författare :Christian Nohr; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; Water and Heat budgets; Deep-water mixing; Internal Wavedrag; Dynamical Sea Ice production; Sea Ice dynamics;

    Sammanfattning : This thesis comprises of model estimates of the water and heat budgets, re-estimating of the budget of deep-water mixing energy, model studies of generation mechanisms for internal waves, sea ice dynamermics and finally sea ice monitoring. Common site for all the studies are the Baltic Sea. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  4. 13. Östersjöns skeppssättningar : monument och mötesplatser under yngre bronsålder

    Författare :Joakim Wehlin; Kristian Kristiansen; Helene Martinsson-Wallin; Mads Kähler Holst; Högskolan på Gotland; []
    Nyckelord :HUMANIORA; HUMANITIES; Ship setting; stone setting; burial; burnt bone; bronze age; Pre-roman iron age; bornholm; gotland; latvia; saaremaa; åland; baltic sea; maritime; landscape; seascape; maritime institution; maritory;

    Sammanfattning : During the Late Bronze Age, the number of metal objects in the Baltic Sea region increased tremendously.  Mobility and interaction in this northern inland sea intensified. This occurred in a period of prehistory when the ship was the predominant symbol in southern Scandinavia. LÄS MER

  5. 14. Silicon cycling in the Baltic Sea : Trends and budget of dissolved silica

    Författare :Liana Papush; Åsa Danielsson; Lars Rahm; Petra Tallberg; Linköpings universitet; []
    Nyckelord :Dissolved silica; trends; nutrient; nutrient ratios; diatoms; Redfield; limitation; eutrophication; riverine load; budget; fluxes; accumulation; retention; optimisation; Baltic Sea; Löst kisel; trender; näringsämne; näringsämnens kvoter; kiselalger; Redfield; tillväxtbegränsning; övergödning; flodtillförsel; budget; flöden; ackumulering; retention; optimering; Östersjön; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The dissolved silicon (DSi) has a crucial role for growth of a large group of primary producers – diatoms and, hence, impact on functioning of the aquatic food web. This thesis contributes to an increased understanding of the modifications of the DSi cycling in the Baltic Sea. LÄS MER

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

    Författare :Filippa Fransner; Jonas Nycander; Christoph Humborg; Andreas Oschlies; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
