SPECMAP Archive NO.1 - Climate Times Series, Downcore and Core-top Data
The SPECMAP Archive No.1 was compiled by Brown University under the direction of A.
Duffy and J. Imbrie with the assistance of A.C. Mix and A. Mcintyre, and funded by
the National Science Foundation. The SPECMAP Archive No.1 contains climate times series
of the past 400,000 years, and basic downcore and core-top data from which these time
series were derived for 17 sediment cores from the Atlantic Ocean. Downcore records
include (1) quantitative data on planktonic species and assemblages which reflect
conditions in the surface waters of the Atlantic ocean; (2) measurements of 0-18,
C-13 difference (planktic and benthic), and Cd/Ca. The age model used to transform
each downcore record into a time series by correlation of its O-18 record with the
published O-18 chronology of Imbrie et al. (1984) is given. Time series with uniformly
spaced samples may be calculated by linear interpolation. The Archive No. 1 contains
101 files, including documentation and bibliographic information. The SPECMAR Archive
No. 1 is available for direct ftp download from NCDC. The SPECMAP Archive No. 1 was
originally submitted to NOAA's National Geophysical Data Center (NGDC) for archive
and was subsequently transferred to NOAA's National Climatic Data Center (NCDC) Paleoclimatology
Group for stewardship..

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. |
