  1. 1. POSSIBLE TIMING OF THE TRANSITION FROM PRE-INDUSTRIAL TO INDUSTRIAL CLIMATE IN THE CENTRAL TO NORTHERN OF SWEDEN, BASED ON PROXY DATA FROM TREE-RINGS

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Mika Falkensjö Oppenheim; [2022-09-28]
    Keywords : Tree-ring; maximum latewood density MXD ; Scandinavia; pre-industrial; industrial climate;

    Abstract : Earth’s climate has varied through time, with orbital forcing as the most dominant force on the climate system the last million years, causing glacial-interglacial cycles. The last glacial period ended about 11.6 thousand years (kyr), ago and the last interglacial maximum around 6.5 kyr ago. READ MORE

  3. 2. Elemental variability in tree-rings as indicator for climate change : a case study on beech and oak trees at the Laacher See, Germany

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Ann-Kathrin Wild; [2022]
    Keywords : trace elements; tree-rings; dendrochemistry; dendroclimatology; ITRAX; Laacher See; mofettes; tree-bark; Quercus sp.; Fagus sp.;

    Abstract : The aim of this study was to contribute to the comprehension of the connection of element uptake in trees at the Laacher See in Germany and climatic parameters on different time scales. Understanding the relationship of certain elements in trees and temperature might enable the assignment of extraordinary high peaks in the elemental concentration, which cannot be explained by temperature, to another process as CO2 degassing of the mofettes, which are relics of the volcanic past of the lake.

  4. 3. Using blue light reflectance from high-resolution images (6000 dpi) of Scots pine tree rings to reconstruct three centuries of Scottish summer temperatures

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Alice De Schutter; Karin Markendahl; [2021]
    Keywords : summer temperature reconstruction; climate change; Scotland; Scots pines; ultra-high image resolution; blue intensity; rekonstruktion av sommartemperatur; klimatförändringar; Skottland; skotska tallar; hög bildupplösning; blå intensitet;

    Abstract : Advances in scanner technology have made it possible to obtain high resolution (6000 dpi) images of tree samples. Due to the images’ increased capability of resolving anatomical wood structures, the new technology could be of benefit to dendroclimatology.  This study attempts to expand on Rydval et al.

  5. 4. Osteological Markers of Nutritional Stress on the Swedish Island of Öland: Physiological Effects of Environmental Fluctuations during the Scandinavian Iron Age

    University essay from Lunds universitet/Arkeologi

    Author : Claire Maeve Callahan; [2020]
    Keywords : Old World Drought Atlas; Dendroclimatology; Nutrition; Osteology; Multiple Correspondence Analysis; Skeletal Pathology; Dietary Isotopes; Environmental Reconstructions; Historic Climate; Iron Age; Sweden; Baltic Region; History and Archaeology;

    Abstract : The shift to agriculture as the main form of subsistence practice allowed past peoples the freedom and potential to exploit their natural and man-made environment for personal and societal gain. Decades of archaeological excavations conducted on the Swedish island of Öland have amassed a wealth of information regarding the subsistence and settlement patterns of Iron Age societies. READ MORE

  6. 5. Climate – Tree-Growth Relationships in Central Sweden : An Evaluation of the Palmer Drought Severity Index as a Tool for Reconstructing Moisture Variability

    University essay from Institutionen för naturgeografi och kvartärgeologi (INK)

    Author : Inga Labuhn; [2009]
    Keywords : dendroclimatology; PDSI; drought; precipitation; reconstruction; tree rings; Sweden;

    Abstract : A tree-ring width chronology from Scots pine (Pinus sylvestris L.) was constructed from a xeric site in Stockholm to investigate the relationships between climate and tree growth and to reconstruct past moisture variability. The measure of moisture conditions employed here is a self-calibrating Palmer Drought Severity Index (PDSI). READ MORE
