  1. 1. Managing coastal eutrophication : Land-sea and hydroclimatic linkages with focus on the Baltic coastal system

    Författare :Guillaume Vigouroux; Georgia Destouni; Alice Newton; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; coastal eutrophication; land-coast-sea continuum; management; hydroclimatic change; research gaps; eutrophication modelling; temoporal trends; scoping review; Baltic Sea; Physical Geography; naturgeografi;

    Sammanfattning : Eutrophication endangers coastal ecosystems all over the world and is most often associated with an increase in anthropogenic nutrient loads to coastal waters, which fuel the growth of algae and create a variety of environmental problems. This is also the case for the Baltic Sea where coastal waters may be affected by various land, coast-sea, and hydroclimatic drivers and feedbacks, over different scales, including the eutrophic open sea.

  2. 2. Seagrasses and Eutrophication : Interactions between seagrass photosynthesis, epiphytes, macroalgae and mussels

    Författare :Esther Francis Mvungi; Mats Björk; Thomas J. Lyimo; Jens Borum; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; CO2; epiphytes; eutrophication; mussels; pH; Photosynthetic activities; seagrasses; Ulva; Plant physiology; Växtfysiologi; Plant Physiology; växtfysiologi;

    Sammanfattning : Seagrass meadows are highly productive, ecologically and economically valuable ecosystems. However, increased human activities along the coastal areas leading to processes such as eutrophication have resulted in the rapid loss and deterioration of seagrass ecosystems worldwide. LÄS MER

    Sammanfattning : This dissertation researches how perspectives in western industrial societies communicate about and give meaning to environmental degradation through case studies on the causes and effects of cultural eutrophication—namely nutrient pollution, algal blooms, and dead zones—in the Baltic Sea. Utilizing this approach, this dissertation addresses the ecological problems of cultural eutrophication in marine ecosystems by exposing normative claims humans make about the Baltic Sea and its contents as well as detailing how seas that exceed human expectations may offer insights into negotiating differing perspectives, discrepancies in power, and ways of being among humans and non-humans in marine environments.

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

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

    Sammanfattning : 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. LÄS MER

  5. 5. Predictive Models and Eutrophication Effects of Fish Farms

    Författare :Lennart Nordvarg; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Earth sciences; Fish farm; eutrophication; model; Geovetenskap; Earth sciences; Geovetenskap; Sedimentology; sedimentologi;

    Sammanfattning : Aquaculture has become one of the fastest growing food industries in the world. Like many other industries, aquaculture, and especially fish farms may cause negative effects on the environment, such as eutrophication, which is recognised as a major threat to aquatic ecosystems.
