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

   University essay from Uppsala universitet/Institutionen för geovetenskaper

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

   Abstract : 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. READ MORE

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. Reconstructing Past Climate by Grain Size and Magnetic Susceptibility Analysis of Belgium Loess From the Late Quaternary

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Susanna Åberg; [2022]
   Keywords : aeolian dust; Romont; Europe; true loess line; past climate reconstruction; vindtransporterat stoft; Romont; Europa; true loess line; rekonstruktion av tidigare klimat;

   Abstract : Aeolian dust that gets deposited builds up loess sequences that cover 10% of the Earth's continents. Such sequences can be several metres thick with material deposited over thousands of years, and therefore act like archives of past climates. READ MORE

5. 4. Late Quaternary Climate Reconstruction Using Rock - Magnetism in Loess on Portelet, Jersey

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Elias Hero; [2022]
   Keywords : ;

   Abstract : Loess is a very fine aeolian sediment that can be used as a proxy for stadial and interstadial glacialperiods. To understand how Earth’s climate have changed and what effects that change have had on theplanet and life on it we can use climate archives. READ MORE

6. 5. 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
