LDEO Carbon 14 Data from Selected Sea floor Cores

browse graphicsample locations in study area
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.

Lineage Statement Data originally submitted to NOAA's former National Geophysical Data Center (NGDC) then transferred to the former National Climatic Data Center (NCDC) Paleoclimatology for stewardship, both centers are now part of NOAA's National Centers for Environmental Information (NCEI). Processing and lineage prior to transmission to NGDC are unknown.
