  1. 1. THE FIRST ACTIVE ACID SULFATE SOIL FOUND OUTSIDE THE BALTIC BASIN, IN VISKA VALLEY WEST COAST OF SWEDEN

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Johanna Bergström; [2023-09-15]
    Nyckelord :Acid sulfate soil; AS soil; ERT measurements; resistivity; Baltic basin; Swedish west coast; acidification; Tapes transgression;

    Sammanfattning : Acid sulfate (AS) soils are naturally formed but are responsible for environmental problem due to its low pH. Drainage of active AS soils can lead to mobilization of harmful metals and a severe pH drop in nearby aquatic environments, which in turn may harm the ecological conditions. LÄS MER

  3. 2. Acid sulphate soil in Falkenberg on the west coast of Sweden - The first discovery of active acid sulphate soil outside the Baltic Basin

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Ida Kling Jonasson; [2020-09-09]
    Nyckelord :Acid sulphate soil on the Swedish west coast; formational environment; Tapes transgression; Resistivity measurements; Baltic Basin;

    Sammanfattning : Active AS soil has several negative impacts on the environment due to their ability to severely decrease pH-values and mobilize metals bound in the soil. The negative impacts can especially be seen in aquatic environments that drains an active AS soil. LÄS MER

  4. 3. Holocene lake-level changes in the Siljan Lake District – Towards validation of von Post’s drainage scenario

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Savvas Paradeisis-Stathis; [2020]
    Nyckelord :Lake Siljan; Dalarna; basin isolation; catastrophic drainage; early Holocene; lake sediments; XRF scanning; C N ratio; magnetic susceptibility; pollen; Ancylus Lake; Earth and Environmental Sciences;

    Sammanfattning : The Dalarna province in south-central Sweden shows a great variety of geological evidence from the Late Quaternary. A peculiar deglaciation pattern, along with unique hydrological conditions, has left a lot of space for speculations over the palaeoenvironmental conditions during the early Holocene. LÄS MER

  5. 4. Hydrological and chloride transport processes in a small catchment of the Norrström Basin : a MIKE SHE modelling approach

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

    Författare :Zhuhuan Liu; Chen Zhou; [2019]
    Nyckelord :MIKE SHE; Hydrological Modelling; Kringlan; Water Balance; Particle Tracking;

    Sammanfattning : Water is ubiquitous on our planet and constitutes a vital part of ecosystems. It supports the life of all beings on the earth while simultaneously evokes water-related issues such as water shortage, water contamination. As UN advocates, a globally shared blueprint for available clean water is depicted in Sustainable Development Goals (SDGs). LÄS MER

  7. 5. Analys av bottensediment från västra Gotlandsbassängen i Egentliga Östersjön

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Gustav Hållenius; [2018]
    Nyckelord :Baltic Sea; eutrophication; phosphorus; metal; sediment; Östersjön; övergödning; fosfor; metall; sediment;

    Sammanfattning : Rapporten ämnar undersöka bottensediment bärgade från ett område i västraGotlandsbassängen i Östersjön. Östersjön är ett ansträngt bräckvattenhav medutbredda övergödningsproblem, döda bottnar och hotad biologisk fauna. LÄS MER
