1. 3D modelling and resistivity measurements for hydrogeological assessments in the northern part of Vombsänkan
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : 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. LÄS MER
2. Diatoms from the late Holocene of the western Chukchi Sea, Arctic Ocean: environmental signals and palaeoceanography
Master-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaperSammanfattning : 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. LÄS MER
3. Reconstruction of paleoclimate and loess provenance during the last glacial in Jersey using XRF analysis
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : 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. LÄS MER
4. Litologi, sedimentologi och kolisotopstratigrafi över krita–paleogen-gränsintervallet i borrningen Limhamn-2018
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Krita-paleogen-gränsen har länge varit central i diskussioner mellan forskare runt om i världen, då den markerar/sammanfaller med utdöendet av 75% av jordens arter till följd av ett enormt asteriodnedslag på Chicxulúbhalvön i Mexiko. Gränsintervallet är vida utbrett i sedimentära lagerföljder som bildades under denna tid, och kan identifieras genom sina unika kemiska egenskaper och karakteristiska litologier skapad av material från nedslaget som spreds kring jorden.

5. Stratigraphy and dating of a lake sediment record from Lyngsjön, eastern Scania : human impact and aeolian sand deposition during the last millennium
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : 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. LÄS MER
