Prior to AD 1736, net accumulation values marked with an asterisk (*), represent average values over intervals bounded by volcanic events identified in the core chemistry and provisionally matched with known volcanic events (Simkin et al. 1981). Errors in accumulation values are estimated to vary from ñ 0.025 m at the surface to ñ 0.075 m at AD 1693. Future analyses may enable the meaned sections to be resolved into annual increments. Mean annual values of _180 are terminated at AD 1736 although analysis interval data are available to the base of the core, estimated to correspond to AD 1688. A graph of this raw data is shown in Holdsworth et al. 1989).
