  1. 1. TRACKING WASTEWATER EMISSIONS IN RIVERS ENTERING GULF OF BOTHNIA COAST

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

    Författare :Helen Mkandawire; [2023]
    Nyckelord :Nutrients inputs; wastewater; coastal waters; Gulf of Bothnia; wastewater emissions; nutrient transportation; marine water; nutrient loading; eutrophication.;

    Sammanfattning : The Gulf of Bothnia consists of two sub-basins in the northern Baltic Sea: the Bothnian Sea (salinity 4-5‰) and Bothnian Bay (salinity 2-3‰). Changing nutrient concentrations and signs of eutrophication has recently been observed in the Gulf of Bothnia. LÄS MER

  3. 2. Uttrycksmönster av kiseltransportörgener hos Chaetoceros affinis med realtids-PCR

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Nikolaj Gubonin; [2021]
    Nyckelord :diatom; SIT; kisel; realtids-PCR; relativt genuttryck; konkurrens;

    Sammanfattning : Diatoms are photosynthetic protists that reside in aquatic environments. A unique feature of diatoms is their cell wall structure made of silica. Silicon is a limiting nutrient for diatoms. The bioavailable form of silicon in aquatic environments is silicic acid. LÄS MER

  4. 3. Life Cycle Assessment of Lettuce Production Systems : A Case Study Performed at Hollbium

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

  7. 5. Effects of hydrodynamics on mussel larvae settlement and mussel distribution - with a focus on fine-scale velocities in Port Alfred Marina, South Africa

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Magnus Janson; [2020]
    Nyckelord :Larval settlement; hydrodynamics; water velocity; mussel distribution; Port Alfred; South Africa; Technology and Engineering;

    Sammanfattning : Mussels, like other intertidal organisms, depend on the motion of water throughout their entire life cycle. Hydrodynamic forces are essential for the transportation and settlement of mussel larvae, as well as feeding and growth for adult mussels. LÄS MER
