1. Reconstructing Mid-Late Holocene Arctic Climate Using Loess Deposits From Kangerlussuaq, Greenland
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : 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).

2. Grain Size Analysis of Late Pleistocene Loess Deposits, Jersey
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : 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. LÄS MER
3. 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
4. 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
5. Jordlagerföljden i Höjeådalen utifrån nya borrningar
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Jordarternas utbredning över sydvästra Skåne är ett resultat av Weichselistidens komplexa växelverkande isframstötar, där stora mäktiga kvartära avlagringar finns i anknytning till Alnarpssänkan och Lundadalen. Avlagringarna och deras glaciala ursprung är ett historiskt omdiskuterat ämne. LÄS MER
