  3. 7. Mercury accumulation in lake sediments on different time scales – the influence of algal primary production

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Anne Rebotzke; [2023]
    Nyckelord :mercury; lake sediment; primary productivity; algal scavenging; biogenic silica; diatom proxy; chlorophyll-a; organic matter;

    Sammanfattning : The aim of this work is to test the proposed approach of algal scavenging as a driver of sediment mercury (Hg) on different time scales and to gain a better understanding of the mechanisms of Hg accumulation in lake sediments. A 3000-year sediment record from Nylandssjön in northern Sweden was analysed for this purpose, as well as a 20-year sediment record from the seasonal sediment traps of this lake. LÄS MER

  4. 8. 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
