  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. Kartläggning av kvicklera med hjälp av flygresistivitetsmätningar

    M1-uppsats, Högskolan i Jönköping/JTH, Byggnadsteknik

    Författare :Clara Jönsson; Linn Larsson; [2017]
    Nyckelord :Geology; geotechnics; quick clay; sensitivity; resistivity; Geologi; geoteknik; kvicklera; resistivitet; sensitivitet;

    Sammanfattning : Purpose: One of the major soil problems that the construction industry may face is the presence of a certain type of highly sensitive marine clay, known as quick clay. The quick clay possesses properties that allow the clay to move from being relatively stable to on mechanical impact losing virtually all shear strength and act as a viscous mass. LÄS MER
