                             SUMMARY

Carbon-14 data in this file were compiled by W.F. Ruddiman and staff
at the Lamont-Doherty Earth Observatory of Columbia University. Data
include 974 carbon-14 dates from 309 ocean sediments cores, covering
the period from 40,000 years bp to the present worldwide. Estimated
error range is given. Also included are core identifier,
latitude/longitude, water depth, depth in core, institutional
source, laboratory number, and sediment fraction analyzed (total,
bulk, or fine fraction).
