  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; Mittuniversitetet.; [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

  4. 4. Iodine Isotopes (129I and 127I) in the Baltic Sea   Tracer applications & environmental impact

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Peng Yi; Uppsala universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; radioactive 129I; stable 127I; AMS; iodine species; nuclear reprocessing facilities; tracers; Baltic Sea; circulation; water exchange; environmental impact;

    Abstract : 129I is a radioactive isotope (T1/2= 15.7 million years) produced through natural and anthropogenic pathways, but the anthropogenic production is presently dominating the Earth’s surface environments. READ MORE

  5. 5. Genetic Aspects of Environmental Disturbances in Marine Ecosystems Studies of the Blue Mussel in the Baltic Sea

    University dissertation from Huddinge : Södertörns högskola

    Author : Josefine Larsson; Södertörns högskola.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Blue mussel; Baltic Sea; anthropogenic disturbance; pollution; sewage effluents; harbors; genetics; genomics; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Abstract : Anthropogenic environmental changes can serve as drivers for evolutionary responses in wild populations. To predict the long-term impact of anthropogenic changes on populations, it is crucial to understand the genetic effects caused by these disturbances. READ MORE
