  1. 6. Environmental and climatic changes in the Baltic Sea and the eastern Mediterranean Sea : as recorded by pigments and isotopes in sediments

    Författare :Johanna Borgendahl; Rolf Hallberg; Joyanto Routh; Stefano Bernasconi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap;

    Sammanfattning : This thesis is a study of Holocene sapropels from two semi-enclosed seas; the Baltic Sea and the Mediterranean Sea. Sapropels are sedimentary layers with organic C > 2%. LÄS MER

  3. 7. Speleothems from Warm Climates : Holocene Records from the Caribbean and Mediterranean Regions

    Författare :Meighan Boyd; Karin Holmgren; Ian J. Fairchild; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 8. Transport of Mercury Species in the Environment. Exchange between Oceanic Waters and the Atmosphere

    Författare :Maria Andersson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mercury; dissolved gaseous mercury; elemental mercury; evasion; flux; Mediterranean Sea; North Atlantic Ocean; Arctic Ocean; accumulation; in-situ measurements; on-line measurements;

    Sammanfattning : Mercury is an element present in the earth crust as well as a component in the atmosphere. During centuries mercury has been released by natural sources, e.g. volcanic eruptions, evasion from water surfaces and degassing from soil. LÄS MER

  5. 9. Contacts and Trade at Late Bronze Age Hazor : Aspects of Intercultural Relationships and Identity in the Eastern Mediterranean

    Författare :Kristina Josephson Hesse; Thomas B. Larsson; Amnon Ben-Tor; Bozena Werbart; Magnus Ottosson; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Hazor; Canaan; Eastern Mediterranean; Late Bronze Age; contacts; trade; temple architecture; Mycenaean pottery; Cypriote pottery; interregional interaction networks; emulation; peer polity interaction; centre-periphery approach; Archaeology; Non-European; Arkeologi; utomeuropeisk; Archaeology; Arkeologi; Archaeology;

    Sammanfattning : Hazor’s role in an international Late Bronze Age context has long been indicated but never thoroughly investigated. This role, I believe, was more crucial than previously stressed. LÄS MER

  7. 10. 231Pa and Th isotopes as tracers of deep water ventilation and scavenging in the Mediterranean Sea

    Författare :Sandra Gdaniec; Per Anerson; Carl-Magnus Mörth; Matthieu Roy-Barman; Helen Coxall; Per Roos; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protactinium; Thorium; particle transport; deep water circulation; geokemi; Geochemistry;

    Sammanfattning : The naturally occurring isotopes 231Pa and 230Th are used as tracers of marine biogeochemical processes. They are both produced from the radioactive decay of their uniformly distributed uranium parents (235U and 234U) in seawater. LÄS MER
