SPECMAP Archive NO.1 - Climate Times Series, Downcore and Core-top DataEntry ID: gov.noaa.ngdc.G00997
Abstract: ABSTRACT: 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 NGDC's web server.
