  4. 17. Holocene Environmental Change of Southern Öland, Sweden

    Author : Kerstin Alm Kübler; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Pollen analysis; Öland; Sweden; heath vegetation; landscape history; Fagus; beach ridges; numerical analysis; Geovetenskap; Earth sciences; Geovetenskap; Quarternary Geology; kvartärgeologi;

    Abstract : This thesis describes Holocene environmental change in Ottenby, southern Öland,Sweden. Analyses of pollen sequences collected distally in the Littorina ridge and in fentroughs between lower laying beach ridges show the vegetation history during twoperiods, the first around 8000 BP and the second from 0/500 AD to about present time.

  5. 18. Holocene Climate in Central and Southern Sweden : Quantitative Reconstructions from Fossil Data

    Author : Karin Antonsson; Keith Bennett; Heikki Seppä; Andy Lotter; Uppsala universitet; []
    Keywords : Quaternary geology; pollen analysis; climate reconstructions; transfer functions; vegetation dynamics; Sweden; Kvartärgeologi;

    Abstract : In quantitative palaeoecology modern species-environmental relationships can be statistically modelled, and recent development has made the calibration models more statistically robust. These models are used to transform fossil assemblages to quantitative estimates of past environmental conditions. READ MORE

  6. 19. Influence of solar activity and environment on 10Be in recent natural archives

    Author : Ann-Marie Berggren; Ala Aldahan; Göran Possnert; Anne Hormes; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cosmogenic isotopes; beryllium; ice cores; varved lake sediments; accelerator mass spectrometry; co-precipitation; Quaternary geology; Kvartärgeologi;

    Abstract : Understanding the link between the Sun and climate is vital in the current incidence of global climate change, and 10Be in natural archives constitutes an excellent tracer for this purpose. As cosmic rays enter the atmosphere, cosmogenic isotopes like 10Be and 14C are formed. READ MORE

  7. 20. Event stratigraphy for the Last Glacial-Holocene transition in eastern middle Sweden

    Author : Jonas Björck; Michael J.C Walker; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Last Glacial-Holocene transition; event stratigraphy; eastern middle Sweden; pollen; plant macrofossils; marine calcareous fossils; microtephra; radiocarbon dating; clay varve chronology; GRIP; ice-core chronology; calendar year chronology; Preboreal oscillation; Yoldia Sea; Baltic Ice Lake; Quaternary Geology; kvartärgeologi;

    Abstract : This thesis outlines an event stratigraphy for the Last Glacial-Holocene transition in eastern middle Sweden. Events are short-lived occurrences that have left traces in the geological record and which, therefore, may be used for correlation and inter-regional comparisons. READ MORE
