LDEO Carbonate Data - CaCO3 Percentages for 328 Sediments Cores, Principally from
The Atlantic Ocean Spanning 100,000 to 200,000 Years bp
|
LDEO Carbonate data were compiled under the direction of A. Esmay and W.F. Ruddiman
at the Lamont-Doherty Earth Observatory of Columbia University. Data include CaCO3
percentages by interval down core for 328 sediments cores, principally from the Atlantic
ocean. Data are derived primarily from two sources. First, cores analyzed during the
CLIMAP project to generate stratigraphic control on cores from key deep-sea regions.
Second, cores analyzed using almost entirely National Science Foundation funds, but
through smaller grants to individuals and institutions. On average, cores span intervals
of time of 100,000 to 200,000 years and have been analyzed at time steps of a few
thousand years. Several cores span only the last deglaciation; a few cores cover much
longer intervals, up to 3 million years. Samples are annotated as either bulk sediment,
or fine-fraction. Data are available for free download. Data were originally submitted
to NOAA's National Geophysical Data Center (NGDC) for archive and were subsequently
transferred to NOAA's National Climatic Data Center (NCDC) Paleoclimatology Group
for stewardship.
