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. Reconstructing Mid-Late Holocene Arctic Climate Using Loess Deposits From Kangerlussuaq, Greenland

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : William Mörtsjö Zung; [2023]
   Keywords : ;

   Abstract : The current geological epoch, the Holocene, began 11,700 years ago. During this time, a thermal maximum in temperature was reached somewhere during the early-middle stage at 8-5 kyrs ago which was followed by a period of neoglacial cooling, culminating in the little ice age (LIA).

4. 3. 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

5. 4. 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

6. 5. Aeolian and Pedogenic Processes of Loess in Southern England

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Ragna Orbe; [2019]
   Keywords : loess; Pegwell Bay; grain size distribution; magnetic susceptibility; past-climate reconstruction; lössavlagringar; Pegwell Bay; partikelstorleks distribution; magnetisk mottaglighet; historisk klimatrekonstruktion;

   Abstract : Loess is an aeolian sediment that can be utilized as a detailed proxy of past climate, since it is one of few sediments that is deposited directly from the atmosphere on land. Investigation of loess deposits can give understanding of past regional and local wind circulation patterns and velocities, atmospheric dustiness, as well as paleo-precipitation and weathering conditions.
