  1. 1. Reconstructing Past Climate by Using XRF and Loss of Ignition on Loess from Adventdalen, Svalbard : Rekonstruktion av tidigare klimat genom attanvända XRF analys och antändningsförlust på lössavlagringar från Adventdalen, Svalbard

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Albin Andreasson; Noa Lind; [2023]
    Keywords : Svalbard; loess soil; XRF; weathering; climate change;

    Abstract : By analyzing the texture, composition and chemical composition of loess soils, the reconstruction ofpast climate regimes is enabled, which can improve our understanding of current and future climatechange. Properties such as grain size and composition, mineralogy, organic matter and chemicalcomposition can provide information about which environmental factors were present during thedeposition of the sediment, which can lead to a detailed picture of the climate history of a site.

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

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

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

    Abstract : 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. READ MORE

  4. 3. Post-IR IRSL dating of K-feldspar from Loess at Lowland Point, SW England : Developing a Chronology for Past Climate Records

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Elin Törnqvist; [2022]
    Keywords : loess; post-IR IRSL; Lowland Point; SW England; Quaternary; löss; post-IR IRSL; Lowland Point; England; kvartär;

    Abstract : Loess deposits are terrestrial clastic sediments derived from aeolian deposition. Loess is transported in periglacial conditions and was mainly deposited in cold environments around glaciers during the Quaternary period. READ MORE

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

    University essay from Lunds universitet/Geologiska institutionen

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

    Abstract : 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.

  6. 5. Development of a Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Josephine Lindsey-Clark; [2021]
    Keywords : Neutron Activation Analysis; NAA; European Spallation Source; ESS; Lund Ion Beam Analysis Facility; LIBAF; Gamma-Ray Spectra; Physics and Astronomy;

    Abstract : This report outlines the first stages of the development of the Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility in the Division of Nuclear Physics, Lund University. The motivation for this project is to use the Neutron Activation Analysis detection technique for environmental monitoring around the European Spallation Source, soon to come into operation. READ MORE
