  2. 1. Holocene environmental changes and climate variability in the Eastern Mediterranean : Multiproxy sediment records from the Peloponnese peninsula, SW Greece

    Author : Christos Katrantsiotis; Stefan Wastegård; Rienk Smittenberg; Jan Risberg; Elin Norström; Sherilyn Fritz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mediterranean; Greece; Peloponnese; Holocene; sediments; diatoms; n-alkanes; stable isotopes; tectonics; climate variability; monsoons; NAO; NCP; Physical Geography; naturgeografi;

    Abstract : This thesis presents multiproxy reconstructions of the mid to late Holocene climate and environmental changes in the Peloponnese peninsula, SW Greece. The combined dataset consists of diatom, biomarker and X-ray fluorescence spectrometry (XRF) elemental data in radiocarbon-dated sediment cores taken from the Agios Floros fen and the Gialova Lagoon in SW Peloponnese and the Ancient Lake Lerna in NE Peloponnese.

  4. 2. 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.

  5. 3. Archaeological and Historical Reconstructions of the Foraging and Farming Communities of the Lower Zambezi : From the mid Holocene to the second Millennium AD

    Author : Hilário Madiquida; Paul Sinclair; Karl-Johan Lindholm; Dr Munyaradzi Manyanga; Uppsala universitet; []
    Keywords : HUMANIORA; HUMANITIES; Mozambique; Zambezi Valley; Late Stone Age; Early Farming Communities; Long-distance trade; Afro-Portuguese; Written sources; Archaeology; Historical Ecology; Archaeology; Arkeologi;

    Abstract : In this thesis I combine new archaeological surveys and excavations together with the historical and ethnographic sources, to construct a long term settlement history and historical ecology of the lower Zambezi River valley and delta region, in Mozambique. The evidence presented indicates that people have settled in the area since the Late Stone Age, in total eight new archaeological sites have been located in archaeological surveys. READ MORE

  6. 4. Vegetation history, human impact and palaeogeography of West Estonia : Pollen analytical studies of lake and bog sediments

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Vegetation history; human impact; palaeogeography; shoreline displacement; The Baltic Sea; the Yoldia Sea; the Ancylus Lake; the Litorina Sea; pollen analysis; macro fossil analysis; bog and lake sediments; radiocarbon dating; Holocene; Estonia; Geovetenskap; Earth sciences; Geovetenskap; Earth Sciences with Specialization Environmental Analysis; geovetenskap med inriktning mot miljöanalys;

    Abstract : The history of Holocene vegetation in western Estonia and the West Estonian Archipelago is described. Early Holocene sea level changes in the area are reconstructed, and human impact on the vegetation during the Late Holocene is discussed West Estonia was divided into five study areas (Rummu-Maardu, Mustjärve, Velise-Kiilaspere, Tôstamaa Peninsula, and northern Saaremaa in the West Estonian Archipelago, from north to south).

  7. 5. Modelling the early to mid-Holocene Arctic climate

    Author : Marit Berger; Arne Johansson; Rodrigo Caballero; KTH; []
    Keywords : Arctic; early Holocene; mid-Holocene; climate modelling; paleoclimate; sea ice; climate change;

    Abstract : In the recent past it has become evident that the Earth's climate is changing, and that human activity play a significant role in these changes. One of the regions where the ongoing climate change has been most evident is in the Arctic: the surface temperature has increased twice as much in this region as compared to the global average, in addition, a significant decline in the Arctic sea-ice extent has been observed in the past decades.
