Irregularities in dendrochronological calibration

Abstract

MOST of the ‘wiggles’ in the Suess curve1, which is used for calibrating radiocarbon dates (denoted b.p.; sidereal dates denoted BP) in terms of dendrochronology, are likely to be artefacts2. Curves with almost undiscernible fluctuations have been produced. There are, however, physical reasons for expecting some changes in the 14C content of the atmosphere to have occurred and it is important to locate them by a method that does not depend either on intuition or on minimising deviations over the whole range of the curve4–6.
