  1. 1. Paleoenvironmental and paleoclimatic changes in northeast Thailand during the Holocene

    Författare :Sakonvan Chawchai; Barbara Wohlfarth; Richard Bindler; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Paleoenvironment; paleoclimatic; sediment; peat; multi-proxy; Asian monsoon; the Holocene; Marine Geology; maringeologi;

    Sammanfattning : The long-term climatic and environmental history of Southeast Asia is still fragmentary. This thesis therefore aims at studying lake sediment/peat sequences using a multi-proxy approach to reconstruct the environmental history and the impact of past changes in monsoon variability and intensity on lake ecosystems in Thailand.

  3. 2. Holocene development of Lake Lögurinn and Eyjabakkajökull : a multi-proxy approach

    Författare :Johan Striberger; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Iceland; the Holocene; lake sediments; varves; glacial meltwater variability; surge periodicity; palaeoclimate;

    Sammanfattning : The North Atlantic region has experienced significant climate fluctuations during the Holocene. It has been shown that these fluctuations affected the terrestrial environment in Iceland, including its glaciers and ice caps. LÄS MER

  4. 3. Marine multi-proxy records of late Quaternary climate change from the Atlantic Ocean

  5. 4. The Eemian Interglacial at Sokli, northern Finland : A multi-proxy environmental and climatic reconstruction based on a 9 m long lacustrine sediment sequence

    Författare :Anna Plikk; Karin F. Helmens; Oliver Heiri; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Last Interglacial MIS5e ; northern Europe; palaeolimnology; palaeoecology; temperature reconstruction; multiple proxies; climate dynamics; climatic events; kvartärgeologi; Quaternary Geology;

    Sammanfattning : Understanding the fundamentals of the Earth’s climate system during the Quaternary Period (the past ca 2.6 million years) is of imminent interest in light of the reported recent climatic changes. LÄS MER

  7. 5. Dansgaard-Oeschger cycles and Heinrich events in western Europe - A diatom perspective

    Författare :Linda Ampel; Barbara Wohlfarth; Jan Risberg; Sherilyn Fritz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dansgaard-Oescher cycles; Heinrich events; MIS 3 and 2; diatoms; Les Echets; France; Quaternary geology; Kvartärgeologi; Quarternary Geology; kvartärgeologi;

    Sammanfattning : The last glacial period was characterised by several abrupt climatic shifts referred to as Dansgaard-Oeschger (DO) cycles and Heinrich events. These shifts were most frequent between 60,000 and 20,000 years before present coinciding with Marine Isotope Stages (MIS) 3 and 2. LÄS MER
