  1. 1. Mussel farming along the south-Swedish coasts - a possible solution to eutrophication?

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : David Trulsson; [2023]
    Keywords : Mussel farming; Aquaculture; Spatial suitability analysis; Eutrophication; Baltic Sea; Biology and Life Sciences; Earth and Environmental Sciences;

    Abstract : The concept of mussel farming as a mitigator to nutrient pollution is steadily spreading. The southernmost part of Sweden borders the Baltic Sea where the water quality differs between the costs, however, all are affected by eutrophication. READ MORE

  3. 2. The geochemical status of the surface water and the sediments in the estuary of the Sangis River, Kalix, Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Anton Sandberg; [2023]
    Keywords : Framboidal pyrite; dredging; Sangis River; estuary; redox ladder; sediment; sediment cores; SEM-EDS;

    Abstract : It has been common in forestry and agriculture to drain waterlogged areas through ditching in order to cultivate them. The ditches that drain water are usually connected to some watercourse, such as a river. READ MORE

  4. 3. The role of bed sediments for fractionation of phosphorus in remediated ditches in Sweden

    University essay from SLU/Dept. of Soil and Environment

    Author : Emma Ryding; [2022]
    Keywords : Phosphorus fractionation; agricultural stream; sediment; two-stage ditch; eutrophication;

    Abstract : Sweden’s environmental quality objectives “A varied agricultural landscape” and “Zero eutrophication”, aims to ensure food production while reducing negative impact from fertilizers on the environment. The input ceilings of nutrient concentrations in the Baltic Sea are still critical. READ MORE

  5. 4. As I live and breathe! : The effects of hypolimnic oxygenation on benthic macroinvertebrate and zooplankton assemblages

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Rashid Kadhim; [2022]
    Keywords : lake hypoxia; benthic macroinvertebrates; chironomids; zooplankton;

    Abstract : Exacerbated deep-water hypoxia, brought about by anthropogenic-derived dissolved organic carbon (DOC) input, has potentially detrimental impacts on organisms residing in freshwater ecosystems. Oxygenation of the water column is a potential management strategy to mitigate this impact, and used to alleviate DOC induced oxygen depletion. READ MORE

  6. 5. Developing a supervised machine learning model for an optimised aluminium addition based on historical data analytics, for clean steelmaking

    University essay from KTH/Materialvetenskap

    Author : Arun Kumar Thakur; [2022]
    Keywords : Clean steelmaking; Data analytics; De-oxidation; Machine learning; Ren ståltillverkning; Dataanalys; Deoxidation; Maskininlärning;

    Abstract : De-oxidation is an important process in clean steelmaking. Al (Aluminium) is mainly used as de-oxidant and controls the final oxygen content and impact the sulphur removal in steel. Adding optimum amount of Al is critical for steel cleanliness and to reduce cost. READ MORE
