  1. 1. 3D modelling and resistivity measurements for hydrogeological assessments in the northern part of Vombsänkan

    University essay from Lunds universitet/Geologiska institutionen

    Author : Farid Khorshidian; [2023]
    Keywords : Conceptual 3D modelling; Resistivity; Hydrogeology; Blue Transition; Vombsänkan; Vombverket; Earth and Environmental Sciences;

    Abstract : The geology of Vombsänkan is characterized by a complex sequence of Quaternary deposits overlying the Paleozoic sedimentary bedrock. The area is 759 km2 and has recorded several ice advances followed by glacial retreats and ice melting. READ MORE

  3. 2. Diatoms from the late Holocene of the western Chukchi Sea, Arctic Ocean: environmental signals and palaeoceanography

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Erik Browaldh; [2022]
    Keywords : diatoms; late holocene; SWERUS-L2-2-PC1; Herald Canyon; Chukchi Sea; ice-algae; sympagic; cryophilic; warm water diatom; Bering Sea Water species; bottom water temperature; BWT; benthic foraminifera; palaeothermometry; ice dynamics; Fragilariopsis; Fossula arctica; Paralia sulcata; Shionodiscus oestrupii; Thalassiosira simonsenii; Chaetoceros; Chaetoceros sp. 7;

    Abstract : The sediment Core SWERUS-L2-2-PC1 (2PC) retrieved from the Chukchi Sea, Arctic Ocean sits in an oceanographically dynamic location at the Arctic-Pacific Ocean gateway. The 8.3 m-long core was retrieved in Herald Canyon at the marginal ice zone at 57 m depth. READ MORE

  4. 3. Reconstruction of paleoclimate and loess provenance during the last glacial in Jersey using XRF analysis

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Matilda Persson; [2022]
    Keywords : loess; origin; La Motte; XRF; Quaternary; weathering; climate; lössjord; ursprung; La Motte; XRF; kvartär; vittring; klimat;

    Abstract : With our changing climate it becomes more vital to understand the processes that control climate change in order to better understand possible future shifts. By doing this, predictions can be made about future climates and better prepare us for them. READ MORE

  5. 4. Stratigraphy and dating of a lake sediment record from Lyngsjön, eastern Scania : human impact and aeolian sand deposition during the last millennium

    University essay from Lunds universitet/Geologiska institutionen

    Author : Marijana Stevic; [2019]
    Keywords : aeolian activity; human impact; geochemistry; lake sediments; pollen; Earth and Environmental Sciences;

    Abstract : A small lake in north-eastern Scania, southern Sweden, Lake Lyngsjön, reveals a long history of aeolian sand drift based on a 3 meter long sediment sequence covering the last approximately 1400 years. Human impact, primarily through intensified land use and decreased forest cover, has periodically led to increased aeolian sand drift both locally and regionally. READ MORE

  6. 5. The Neoproterozoic Visingsö Group of southern Sweden : lithology, sequence stratigraphy and provenance of the Middle Formation

    University essay from Lunds universitet/Geologiska institutionen

    Author : Viktor Ahrenstedt; [2018]
    Keywords : Neoproterozoic; Visingsö Group; sequence stratigraphy; provenance; lithology; Earth and Environmental Sciences;

    Abstract : The depositional setting of the Neoproterozoic Visingsö Group has long been a subject of discussion. This study aims to provide additional insights into the lithological composition and provenance of the sediments and to provide a sequence stratigraphic framework in order to define the depositional setting.
