A Novel Approach for Developing High-Resolution Sub-Fossil Peat Chronologies with 14C Dating

From the 18th International Radiocarbon Conference held in Wellington, New Zealand, September 1-5, 2003.Sub-fossil sections from a Florida wetland were accelerator mass spectrometry (AMS) dated and the sedimentological conditions were determined. 14C data were calibrated using a combined wiggle-match and 14C bomb-pulse approach. Repeatable results were obtained providing accurate peat chronologies for the last 130 calendar yr. Assessment of the different errors involved led to age models with 3-5 yr precision. This allows direct calibration of paleoenvironmental proxies with meteorological data. The time frame in which 14C dating is commonly applied can possibly be extended to include the 20th century.The Radiocarbon archives are made available by Radiocarbon and the University of Arizona Libraries.
