  1. 1. Impact of Sea Surface Temperature and Salinity on Phytoplankton blooms phenology in the North Sea

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Krystyna Muszel; [2023]
    Nyckelord :Geography; GIS; North Sea; phytoplankton; bloom; phenology; remote sensing; TIMESAT software; Earth and Environmental Sciences;

    Sammanfattning : Various environmental forcings can affect phytoplankton blooms, resulting in changes in bloom timing and abundance, which can have many far-reaching consequences. Understanding bloom phenology is crucial to predict and counter any potential harmful changes. LÄS MER

  3. 2. 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. Aluminiumbehandling som sjörestaureringsåtgärd i Stora och Lilla Ullfjärden

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Maja Sellergren; [2022]
    Nyckelord :Aluminum treatment; lake restoration; algal blooms; Bayesian decision analysis; Aluminiumbehandling; sjörestaurering; algblomning; bayesiansk beslutsanalys;

    Sammanfattning : Stora och Lilla Ullfjärden är två sjöar som tillhör den innersta delen av en vik i Mälaren. Här har den höga fosforbelastningen länge varit ett problem då den leder till kraftig algblomning varje år. LÄS MER

  5. 4. Feasibility Investigation of Floating PV in Hydro reservoirs : A case study on tropical and mediterranean climatic regions

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Adithi Prasannalal Sheena; [2021]
    Nyckelord :Floating PV; HOMER Pro; tropical; mediterranean;

    Sammanfattning : To secure the growing energy demand due to the rise in population and technological advancements, countries worldwide are looking for alternatives or complementary generation sources to support the existing grid infrastructure and power generating system. The increase in global temperature and climate change forces each country to switch to clean energy production. LÄS MER

  7. 5. Long-term phosphorus trends in Swedish rivers and streams : widespread and persistent nutrient decline

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Sara Camiolo; [2021]
    Nyckelord :eutrophication; rivers; streams; phosphorus;

    Sammanfattning : Phosphorus (P) is often considered the limiting nutrient for freshwater productivity because of its relevant role in regulating algal production and determining community composition. The concern for increasing anthropogenic P inputs registered since the last century has shaped environmental policies around the world to limit the effects of algal bloom (also known as eutrophication) in freshwater ecosystems through the establishment of maximum threshold nutrient concentrations.
