  2. 16. Tracing environmental change and human impact as recorded in sediments from coastal areas of the northwestern Baltic Proper

    Author : Lena Norbäck Ivarsson; Elinor Andrén; Thomas Andrén; Mikael Lönn; John Anderson; Södertörns högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; paleoecology; diatom stratigraphy; stable nitrogen isotopes; hypoxia; nutrient discharge; eutrophication; Medieval Climate Anomaly; Little Ice Age; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Abstract : The eutrophication of the Baltic Sea due to increased anthropogenic nutrient loads during the 20th century is well documented and studied. However, in the Baltic Sea drainage area, humans have affected the environment longer than the environmental monitoring can provide data for. READ MORE

  4. 17. Bio-optics, satellite remote sensing and Baltic Sea ecosystems : Applications for monitoring and management

    Author : Therese Harvey; Susanne Kratzer; Jakob Walve; Petra Philipson; Stiig Markager; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bio-optics; Remote sensing; MERIS; Eutrophication; Baltic Sea; Monitoring; Management; WFD; MSFD; HELCOM; Chlorophyll-a; Secchi depth; Coloured Dissolved Organic Matter; Suspended Particulate Matter; Marine Ecology; marin ekologi;

    Abstract : Earth observation satellites cover large areas with frequent temporal repetition and provide us with new insight into ocean and coastal processes. Ocean colour measurements from satellite remote sensing are linked to the bio-optics, which refers to the light interactions with living organisms and dissolved and suspended constituents in the aquatic environment.

  5. 18. Phenotypic and Genotypic responses in the planktonic diatom Skeletonema marinoi - Effects of Natural Processes and Anthropogenic Stressors

    Author : Susanna Gross; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diatoms; genotype; phenotype; resting cell; eutrophication; spring bloom; diversity; grazing; adaptation; phytoplankton; microalgae; Skeletonema;

    Abstract : Diatoms are one of the most diverse and abundant phytoplankton taxa and are highly important as primary producers, accounting for nearly half of the marine primary production and constituting the base in the marine food web. Despite their high dispersal potential they are genetically diverse and display genetically structured populations. READ MORE

  6. 19. Nitrogen Removal in Created Wetlands : Considerations – Challenges – Possibilities

    Author : Josefin E. Nilsson; Antonia Liess; Stefan Weisner; Eva Lindström; Jennifer Tank; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecosystem services; eutrophication; constructed wetlands; agricultural runoff; denitrification; wetland multifunctionality; climate change; nutrient retention; vegetation; hydrology; greenhouse gas emissions; biodiversity; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Created wetlands in agricultural landscapes deliver a multitude of ecosystem services, one of which is the removal of nitrogen (N) from water to reduce eutrophication. Wetland N removal, primarily through denitrification, is influenced by various factors. READ MORE

  7. 20. The Baltic Sea marine system - human impact and natural variations

    Author : Erik Gustafsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; modelling; salinity; oxygen; nutrients; eutrophication; acidification; climate;

    Abstract : The environmental state of the Baltic Sea system is influenced by both natural and anthropogenic factors. Water exchange with the adjacent ocean and within the system depend on large-scale atmospheric circulation and properties of the straits separating the different sub-basins. READ MORE
