Weight Percentage of Calcium Carbonate for 17 Equatorial Pacific Cores from Brown University
Weight percentages of calcium carbonate in this file were compiled by J. Farrell and
W. L. Prell of Brown University for 17 equatorial Pacific Ocean sediment cores. Cores
are identified by cruise and core id. Depth-in-core information and estimates of sediment
age, by depth, in millions of years (Ma) are included. Carbonate percentages are weight
percent of bulk samples, rounded to the nearest integer. Models used to generate (by
linear interpolation) ages also included in table form. Ages are based primarily on
paleomagnetic stratigraphy, refined by oxygen isotope stratigraphy, and correlation
of CaCO3 events among cores, and range from 0 to 4 million years. Comments on biostratigraphy,
delta oxygen 18, calcium carbonate events, and core quality are also included on age
model tables. These data were originally submitted to NOAA's National Geophysical
Data Center (NGDC) for archive and subsequently transferred to NOAA's National Climatic
Data Center (NCDC) Paleoclimatology Group for stewardship. These data are available
for direct download from NCDC.

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. |
