1. Loess as an Environmental Proxy for Reconstruction of Palaeoclimate in the High Arctic
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : 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
2. 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).

3. Variations in depositional environments of the Paleogene Firkanten Formation across Adventdalen, from Operafjellet to Breinosa
Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaperSammanfattning : The lowermost Paleogene clastic infill of the Central Spitsbergen Tertiary Basin, the coal bearing Firkanten Formation, has been the subject of study for researchers in the past but little focus has been on the northeast edge of the basin until now. Due to the economic potential of the coal seams in the formation, the Norwegian mining company, Store Norske Spitsbergen Grubekompani (SNSG), has for several years conducted core drilling in key locations in basin, and for decades, they have given an access to their core material to researchers.

4. En detaljerad undersökning av kalkstenslager i den mellanordoviciska gullhögenformationen på Billingen i Västergötland
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Under mellanordovicium täcktes paleokontinenten Baltica av ett grundhav och i det temperade klimatet som rådde avsattes långsamt kallvattenkarbonater som kom att täcka stora delar av paleokontinenten. Idag har merparten av dessa sedimentlager eroderat bort och kalksten har endast bevarats på spridda platser i Sverige. LÄS MER
5. Bogged down: Human preservation and decomposition. Using forensic scoring methods to assess three bog bodies from Denmark, England & Ireland.
Master-uppsats, Lunds universitet/ArkeologiSammanfattning : This work looks at three case studies from bog body research in Denmark, England and Ireland in order to investigate the variation of human decomposition in different depositional environments and the application of forensic methods to the area of bog body research in archaeology. The work attempts to assess the chosen case studies using an established forensic scoring method by Heaton et al (2010) and discusses the possible benefits of using an appropriately adapted scoring method for bog body research.
