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

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Christian Nohr; Göteborgs universitet.; Gothenburg University.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; Water and Heat budgets; Deep-water mixing; Internal Wavedrag; Dynamical Sea Ice production; Sea Ice dynamics;

    Abstract : 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. READ MORE

  2. 2. Ecophysiological responses of Baltic and Atlantic Fucus vesiculosus to environmental factors

    University dissertation from Sundsvall : Mittuniversitetet

    Author : Charlotta A Nygård; Nils Ekelund; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; acclimation; Atlantic; Baltic Sea; Bothnian Sea; Cd; Fucus vesiculosus; growth; high PAR; Pb; photosynthesis; salinity; stress; UV-B; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi;

    Abstract : The Baltic Sea is a species-poor ecosystem where marine species coexist with freshwater species. The Baltic Sea offers low salinity, low content of inorganic carbon, long cold winters and no tides. READ MORE

  3. 3. Physiological adaptations in two ecotypes of Fucus vesiculosus and in Fucus radicans with focus on salinity

    Abstract : The in origin intertidal marine brown alga Fucus vesiculosus L. grow permanently sublittoral in the brackish Bothnian Sea, side by side with the recently discovered F. radicans L. Bergström et L. READ MORE

  4. 4. Physiological responses of marine and brackish Fucus vesiculosus L. with respect to salinity

    University dissertation from Sundsvall : Mittuniversitetet

    Author : Maria Gylle; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; acclimation; Bothnian Sea; compatible solutes; desiccation; fluorescence; F. vesiculosus; F. radicans; immunoblot; mannitol; photosynthesis; Rubisco; salinity; Algfysiologi; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi;

    Abstract : The intertidal brown alga Fucus vesiculosus L. is mainly a marine species (34 practical salinity units, psu), but the alga also grows in the sublittoral of the brackish Bothnian Sea (part of the Baltic Sea; 5 psu). READ MORE

  5. 5. Modelling the Dissolved Inorganic Carbon System in the Baltic Sea

    University dissertation from Sundsvall : Mittuniversitetet

    Author : Moa Edman; Göteborgs universitet.; Gothenburg University.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; Kattegat; pH; pCO2; total alkalinity; biogeochemistry; dissolved inorganic carbon; eutrophication; acidification; climate change; numerical modelling;

    Abstract : Oceans are capable of storing part of the emitted anthropogenic carbon dioxide (CO2) due to the formation of carbonic acid and subsequent dissociation. CO2 is also assimilated by biota and the inorganic carbon system is thus coupled to biogeochemical processes. READ MORE
