  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. Arctica Islandica – Annually Banded Mollusc Offers High Temporal Resolution Record Into End Of North Sea Little Ice Age

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Eilidh Towers; [2022]
    Nyckelord :sclerochronology; Arctica islandica; palaeoenvironments; Little Ice Age; radiocarbon reservoir effect;

    Sammanfattning : Sclerochronology affirms the well-established fact that banded growth increments in marine molluscs accurately record oscillations in climate and environment for the past millennia or more. This study considers how such records can enhance understanding of environmental shifts across the 18th to 20th centuries. LÄS MER

  4. 3. OSL dating of the Mesolithic site Nilsvikdalen 7, Bjorøy, Norway.

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Elin Jirdén; [2022]
    Nyckelord :OSL dating; luminescence; SAR protocol; water content; archaeology; Late Mesolithic; Norway.; Earth and Environmental Sciences;

    Sammanfattning : Luminescence dating is a well-established dating method within geological and archaeological research. However, the use of luminescence dating, and more specifically optically stimulated luminescence (OSL), is currently underutilised in Norwegian archaeology. LÄS MER

  5. 4. Technology and market screening for “green” disposable diapers

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Carolina Nealis; [2021]
    Nyckelord :disposable diapers; nappies; green; eco; ecological; Engångsblöjor; miljövänliga; gröna; eco; ekologiska;

    Sammanfattning : Marknadens påstående om att ”använda så lite plast som möjligt” är vilseledande när 5 av 11 miljövänliga blöjmärken observerades innehålla 80-75% fossil baserad plast.  Detta demonstrerar att vilseledande marknadsföring är närvarande på marknaden av miljövänliga engångsblöjor.

  7. 5. Odensjön - A new varved lake sediment record from southern Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Hanna Hertzman; [2021]
    Nyckelord :Varved lake sediment; late Holocene; organic sediments; diatoms; land-use history; southern Sweden; palaeolimnology; Earth and Environmental Sciences;

    Sammanfattning : Annually laminated (varved) sediments provide opportunities to reconstruct climate change and human impact on the environment with high temporal resolution. Depending on the character of the varves, such sediments can provide insight into the delivery of both autochthonous and allochthonous material from the lake and its catch- ment and answer questions regarding both regional and local responses to climate- and land-use changes.
