Research theme: Stable carbon isotopes in tree rings: signs of climatic variations and anthropogenic effects in the Baltic region

Brief description: Search for correlations between stable tree ring carbon isotopes, climate variations and anthropogenic factors in the Baltic region.

Objectives:

  1. measurements of stable carbon isotope discrimination in tree ring samples collected from various locations;
  2. measurements of carbon isotope discrimination during a tree vegetation period;
  3. analysis of dependence of carbon isotope discrimination on the hydrometeorological environment;
  4. analysis of anthropogenic impacts on carbon isotope discrimination.
