1. 1. Loess as an Environmental Proxy for Reconstruction of Palaeoclimate in the High Arctic

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Sara Rognås; [2023]
   Nyckelord :aeolian transport; loess; grain size analysis; loss on ignition; palaeoclimate; Svalbard; Holocene; vindtransporterat material; lössjord; kornstorlek; loss on ignition; paleoklimat; Svalbard; Holocen;

   Sammanfattning : We are currently speeding towards significant changes in the climate of the earth which, if ignored, will lead to severely altered climatic conditions with serious consequences for several species and ecosystems. The polar regions especially are very sensitive to climate changes, and the changes these regions undergo affect the climate on a global scale. LÄS MER

3. 2. The Magnetic Properties and Fabrics of Upper Pleistocene Loess on La Motte, Jersey, and their Palaeoclimate Implications

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Anya Hawkins; [2022]
   Nyckelord :last glacial; magnetic susceptibility; AMS; temperature dependent magnetic susceptibility; palaeowind reconstruction;

   Sammanfattning : The island of Jersey is an interesting location for palaeoclimate reconstruction given the likely impact of variations in North Atlantic climate and European ice sheet extent during the last glacial period considering their proximal location. These last glacial climatic variations are recorded in the loess sequence from La Motte, Jersey and in order to reconstruct these changes, a detailed magnetic analysis was performed. LÄS MER

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

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

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

   Sammanfattning : 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

5. 4. En resa tillbaka i tiden för att förstå framtiden : En undersökning av organiskt material i eoliska lössjordssediment på västra Grönland, Kangerlussuaq.

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Caroline Morin; Jessica Sundman; [2021]
   Nyckelord :Greenland; organic carbon; loss of ignition; loess; paleoclimate; Grönland; organiskt material; loss of ignition; lössjordar; paleoklimat;

   Sammanfattning : Today's changing climate on Earth makes climate research more important than ever. By providing an understanding of the Earth's history and in particular places where large-scale climate change is taking place, for example Greenland, can one get an understanding about how the Earth will react in the future.

7. 5. Investigating the Magnetic Susceptibility of Cornish Loess as a Tool for Understanding the Palaeoclimate of SW England

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Love Tingdal; [2020]
   Nyckelord :loess; palaeoclimate; Lizard Peninsula; Isles of Scilly; palaeoprecipitation; magnetic susceptibility; loess; paleoklimat; Lizard-halvön; Scillyöarna; historisk årsmedelnederbörd; magnetisk susceptibilitet;

   Sammanfattning : Loess is a silty material produced via glacial grinding and its deposition is usually associated with colder periods when there is a considerable increase in atmospheric dust transport. The magnetic susceptibility of loess-palaeosol sequences has been the subject of extensive research within palaeoclimatology as it has proven to be reliable climate proxy. LÄS MER
