   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stable isotopes; U-Th dating; trace elements; stalagmite; speleothem; Mid-Holocene; Caribbean; ITCZ; rapid climate change; climate; Eastern Mediterranean; Peloponnese; Santorini; Neolithic; Alepotrypa Cave; Physical Geography; naturgeografi;

   Abstract : This thesis contributes to increased knowledge on Holocene climate and environmental variability from two complex and sparsely studied areas. Using a speleothem from Gasparee Cave, Trinidad, as a paleoclimate archive, the local expression of the 8. READ MORE

4. 2. Speleothems as environmental recorders : A study of Holocene speleothems and their growth environments in Sweden

   Author : Hanna S. Sundqvist; Karin Holmgren; Anders Moberg; Regine Hock; Frank McDermott; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; speleothems; palaeoclimate; stable isotopes; luminescence; karst hydrology; Holocene; Sweden; Jämtland; Physical geography; Naturgeografi;

   Abstract : The main aim of this thesis was to contribute with detailed information of regional environmental change during the Holocene through studies of speleothems and their growth environments from two caves, Korallgrottan and Labyrintgrottan in northwestern Sweden, and a cellar vault in Uppsala. This was done through studies of stable isotopes and luminescence properties in the speleothems in combination with a detailed monitoring study in Korallgrottan. READ MORE

5. 3. Climate in the eastern Mediterranean during the Holocene and beyond – A Peloponnesian perspective

   Author : Martin Finné; Karin Holmgren; Hanna S. Sundqvist; Georgia Destouni; Neil Roberts; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stable isotopes; U-Th dating; stalagmites; climate variability; flooding history; eastern Mediterranean; southern Greece; Holocene; Pleistocene; Physical Geography; naturgeografi;

   Abstract : This thesis contributes increased knowledge about climate variability during the late Quaternary in the eastern Mediterranean. Results from a paleoclimate review reveal that regional wetter conditions from 6000 to 5400 years BP were replaced by a less wet period from 5400 to 4600 years BP and to fully arid conditions around 4600 years BP.
