A LONG SUB‐FOSSIL OAK TREE‐RING CHRONOLOGY FROM THE NORTH OF IRELAND

Abstract

SUMMARY A 2990 year floating tree‐ring chronology has been constructed using bog oaks from low altitudes in the north east of Ireland. The basic building blocks of this chronology are site chronologies made from the ring patterns of trees from individual sites. The construction of site chronologies and of the 2990 year master chronology are described. Applications of this chronology and its extensions include radiocarbon calibration which is already under way, stable isotope measurements for palaeotemperature estimation, and climatic interpretations based on the ring widths.
