Due to financial restrictions, the EPD is no longer able to provide chronologies in calibrated radiocarbon years BP. Contributors are encouraged to provide together with the pollen data a calibrated radiocarbon chronology, stating explicitly the control points (including the assignment for the top sample) and the calibration software version used. Moreover, due to the same reasons any assessment of chronology for sites without an age-depth model has to be left to the potential EPD users until further funding is granted.
