This data set includes chemistry and ion data collected from a 150 m core recovered from Siple Dome, West Antarctica. The core was drilled during the 1994/1995 field season. Dating of the core was accomplished using annual signals preserved in several chemical species, beta activity profiles, and volcanic horizons. The resulting depth/age scale indicates an age of 1890 A.D. at 24 m, and 850 A.D. at 150 m depth.
