  1. 1. Marine Geology and Holocene Paleoceanographyof the Southern Quark, Baltic Sea

    Master-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Anton Wagner; [2022]
    Nyckelord :Bottom currents; Sortable silt; Radiocarbon dating; Baltic Sea stages; Estuarine circulation; Marine sediment cores; Marine geophysical mapping;

    Sammanfattning : The Understen-Märket trench is located in the Southern Quark and is the only deep-water connection between the Baltic Propper and the Gulf of Bothnia. Bathymetric mapping reveals a number of eroded channels and drift deposits exists on the seafloor, indicating that the area is heavily affected by current activity. LÄS MER

  3. 2. A Method for Evaluating and Mapping Terrestrial Deposition and Preservation Potential- for Palaeostorm Surge Traces. Remote Mapping of the Coast of Scania, Blekinge and Halland, in Southern Sweden, with a Field Study at Dalköpinge Ängar, Trelleborg

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Lykke Lundgren Sassner; [2021]
    Nyckelord :Storm surge; Storm surge formation; Storm patterns in Baltic Sea; Preservation potential; Terrestrial preservation potential and erosion; Earth and Environmental Sciences;

    Sammanfattning : Studier av palaeostormfloder ger bakgrund till inom vilka intevall stormar av olika storlek förväntas återkomma och träffa olika områden. Denna information kan användas vid modellering, riskbedömning och stadsplanering. LÄS MER

  4. 3. Records of environmental change and sedimentation processes over the last century in a Baltic coastal inlet

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Hanna Nilsson; [2019]
    Nyckelord :Baltic Sea; eutrophication; coastal areas; archipelago; laminated sediments; nutrient inputs; carbon and nitrogen content; biogenic silica; sedimentation; environmental impact; marine geology; Earth and Environmental Sciences;

    Sammanfattning : The marine ecosystem in the Baltic Sea is affected by multiple stress factors, e.g. eutrophication and deoxygenation, overfishing and anthropogenic pollution. Here we evaluate the short-term trends of dissolved oxygen in bottom waters and changes in the primary productivity within a coastal inlet in the Baltic Sea. LÄS MER

  7. 5. Acoustic survey of sea floor features in Asköfjärden

    Kandidat-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Kim Lundmark; [2017]
    Nyckelord :Marine Geology; Marine Geophysics; Multibeam; Sub-bottom Profiler; Stockholm Archipelago; Geomorphology; Baltic Sea; Gas Seeps; Methane Gas; Fluid Migration; Groundwater; Acoustic Units; Sediment Profile;

    Sammanfattning : Marine geological surveys in Asköfjärden in the southern Stockholm Archipelago hasrevealed step like features in the sediments on the Baltic sea floor. The aim of this project is toanalyse the steps and possible formation processes from the survey data. LÄS MER
