Inter-regional (central Europe and central Alaska) comparison of lacustrine sediment archives of Late-glacial age is a crucial approach to disentangle local and global characteristics of the abrupt environmental changes 12,900 years ago. The joined inter-disciplinary project will provide an improved understanding of the dynamics of the global environmental change at the Younger Dryas onset, consolidate the current scientific collaboration between the Czech (Charles University + Biology Centre of the CAS) and the US team (University of Alaska, Fairbanks), and allow exchange of the state-of the-art methods and approaches.
