  1. 6. Grain Size Analysis of Late Pleistocene Loess Deposits, Jersey

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Joakim Edlund; [2022]
    Keywords : Jersey; loess; grain size; ice age; past climate; Jersey; löss; kornstorlek; istid; forntida klimat;

    Abstract : As the world faces the effects of rapid climate change it is essential that we understand how the Earth’s climate has evolved in recent geological history. The island of Jersey harbours loess deposits which hold clues to recent climate change which have not been extensively studied. READ MORE

    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. 8. 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. 9. Continuous Presence : A Historical Ecology of Ängesviken, Jämtland

    University essay from Uppsala universitet/Arkeologi

    Author : Petter I. Larsson; [2021]
    Keywords : Landscape archaeology; palynology; paleoecology; patchiness; niche construction; historical ecology; continuous presence; boreal forest; outland utilisation; multidisciplinary analysis; Landskapsarkeologi; skogsarkeologi; pollenanalys; historisk ekologi; Jämtland; utmarksbruk; tvärvetenskaplig analys;

    Abstract : A case study of a prehistoric site named Ängesviken, in eastern Jämtland, is presented in this thesis. Ängesviken is situated in a region that traditionally has been understood as peripheral and without a significant history prior to the Late Iron Age or even the mediaeval period. READ MORE

  6. 10. Investigation of Thermal Maturity of  Organic Matter at the Cambro Ordovician Transition in the Zagros Basin, Iran

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Niall Gibbons; [2021]
    Keywords : acritarchs; thermal maturity; Zagros Basin; hydrocarbons; source rocks; paleoenvironment;

    Abstract : The thermal maturity of sediments from the upper Cambrian to lower Ordovician Mila and Ilbeyk  formations in the Zagros Basin in southwestern Iran is evaluated in this thesis. A number of low-cost,  fast, optical evaluation methods are utilised to assess their effectiveness for providing accurate, well  constrained thermal maturity results. READ MORE
