CORING DEVICES Ancillary Description
Quality The cores were dated using multi-species annual layer counting and combined into one record (see Palmer et al., JGR 106, 2001)

The dating scale is known as LD1 (see Ultra-high-resolution seasonality of trace-ion species and oxygen isotope ratios in Antarctic firn over four annual cycles
Alison Mcmorrow, Tas D. Van Ommen, Vin Morgan, Mark A. J. Curran

This dating scale has been updated in May 2007 to add one year around Tambora region - it is the latest and best dating as of September 2010

The dates provided in temporal coverage are approximate only and cover the span of years over which the ice cores were collected.
