  1. 1. CLIMATE CHANGE AND THE NORWAY SPRUCE TREELINE IN THE CENTRAL SCANDINAVIAN MOUNTAINS Treeline evolution, tree growth and a Blue Intensity summer temperature reconstruction

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Fredrik Karlsson; [2022-09-01]
    Keywords : Treeline evolution; Tree growth; Norway spruce; central Scandinavian mountains; Blue Intensity;

    Abstract : In the context of global change, mountain regions have received increased interest in recent times with researchers trying to answer how such regions may be affected by a changing climate. Treeline environments are sensitive to the impacts of climate change which may significantly alter the characteristics of the regions. READ MORE

  3. 2. 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.

  4. 3. Aerosol Input and Snow Accumulation Rates on the Northern Greenland Ice Sheet : Reconstructed by means of Continuous Flow Analysis (CFA) of 6 shallow firn cores

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Patrick Stephan Zens; [2018]
    Keywords : continuous flow analysis; Greenland; shallow firn core; aerosol; snow accumulation; glaciochemistry; kontinuerlig flödesanalys; Grönland; grunda firnkärnor; aerosol; snöackumulering; glaciokemi;

    Abstract : Ice, firn and snow cores from the Greenland ice sheet offer a unique opportunity to reconstruct past climate conditions. These can be analyzed with continuous flow analysis (CFA) in order to acquire proxy information about ancient atmospheric aerosol concentrations, snow accumulation rates or temperature variations, atmospheric composition, solar activity as well as volcanism and biological activity.

  5. 4. Modeling Land-Cover using Bio-Climate Variables

    University essay from Lunds universitet/Matematisk statistik

    Author : Daniel Kwaku Asiamah-Yeboah; Edward Kofi Nyarko; [2013]
    Keywords : Mathematics and Statistics;

    Abstract : MODELING LAND-COVER USING BIO-CLIMATE VARIABLES Vegetation (land-cover) is an inherent part of the climate system (M.-J. Gaillard et al. 2010). 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
