  1. 1. Benthic metabolism and sediment nitrogen cycling in Baltic sea coastal areas the role of eutrophication, hypoxia and bioturbation

    University dissertation from Department of Geological Sciences, Stockholm Univeristy

    Author : Stefano Bonaglia; Stockholms universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Eutrophication; Sediment; Benthic Flux; Nitrogen Cycle; Denitrification; Baltic Sea; Biogeochemistry; biogeokemi; marin- och brackvattensekologi; Marine and Brackish Water Ecology; marin ekologi; Marine Ecology; geokemi; Geochemistry;

    Abstract : Eutrophication is one of the greatest threats for the Baltic Sea, and one of its more critical consequences is bottom water hypoxia. Nutrient enrichment and oxygen-depletion affect both the deep central basins and a number of coastal areas, even though strategies for nutrient reduction have lately been implemented. READ MORE

  2. 2. Uncertainty measurements and validation of ocean colour data in optically complex waters

    University dissertation from Stockholm, Sweden : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : José M. Beltrán-Abaunza; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ocean colour validation; MERIS; in situ radiometry; water quality; CDOM; marin- och brackvattensekologi; Marine and Brackish Water Ecology;

    Abstract : The thesis addresses validation activities associated with the use of in situ and satellite-based radiometers to assess water quality parameters, such as chlorophyll-a (Chl-a), total suspended matter (TSM) and coloured dissolved organic matter (CDOM- also known as yellow substances, YEL) in CDOM-dominated waters. In paper I, an inter-comparison of in situ radiometers is presented. READ MORE

    University dissertation from Stockholm : Systemekologiska institutionen

    Author : Gustaf Almqvist; Stockholms universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Round goby; Neogobius melanostomus; Apollonia melanostoma; non-indigenous fish; life history characteristics; predation; competition; Gulf of Gdańsk; Baltic Sea.; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Marine ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi Marin ekologi; marin- och brackvattensekologi; Marine and Brackish Water Ecology;

    Abstract : Human mediated transfer of non-indigenous species is considered to be a major threat to global biodiversity. The Ponto-Caspian round goby (Neogobius melanostomus), which has established populations in various regions in Eurasia and North-America, was first observed in Gulf of Gdańsk, Baltic Sea, in 1990.
