  1. 1. SWAT Runoff Modeling and Salinity Estimation in the Odra River Catchment

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Tassilo Thebe; [2023]
    Nyckelord :;

    Sammanfattning : In 2022, a significant fish die-off happened in the Odra River due to a bloomof the toxic gold algae species Prymnesium parvum, which occurs in saline andwarm waters. This event is seen as a major ecological disaster in recent Europeanriver incident history. LÄS MER

  4. 3. Living in a lifeless sea : how the ecological degradation of the Baltic Sea is affecting people living in its coastal zone on Gotland

    Master-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Lara Johanna Katharina Kerschl; [2023]
    Nyckelord :Baltic Sea; ecological degradation; lifeworlds; Gotland; phenomenology;

    Sammanfattning : Facing a number of different environmental problems, such as intense oxygen depletion, overfishing and various forms of marine pollution, the Baltic Sea is one of the most degraded seas on earth. While the aspects of its ecological degradation are well-researched, only few studies have focused on how the Baltic Sea’s state is affecting the 85 million people living in its coastal zone.

  7. 5. Analysis of the water quality dynamics of Lake Vomb; Interactions between water quality profile and cyanobacterial bloom in a eutrophic lake in Sweden

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Wiebke Coenen; [2022]
    Nyckelord :Vombsj¨on; Lake profile; Cyanobacteria; Drinking water; Random Forest; Technology and Engineering;

    Sammanfattning : Lake Vomb, located in Sk˚ane, Sweden, provides water for groundwater infiltration, used for the drinking water supply of several municipalities, including Malm¨o. The lake is in a bad ecological condition with intense algae blooms during summer. Cyanobacteria dominate mentioned blooms in 2021 posing the threat of releasing cyanotoxins. LÄS MER
