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 sediment 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). The LDEO C14 data were originally
submitted to NOAA's National Geophysical Data Center (NGDC) for archive, but were
subsequently transferred to NOAA's National Climatic Data Center (NCDC) Paleoclimatology
Group for stewardship. The data are available for direct download from NCDC's Web
server. |
