Climate: Long-Range Investigation, Mapping, and Prediction (CLIMAP) 18,000 Years Before Present (18k bp) Sediment Data Files

The CLIMAP 18k bp sediment data files were compiled by Oregon State University, and include the work of several major institutions. The files contain micropaleontology in the form of faunal counts of diatoms, planktonic foraminifera, coccoliths, and radiolaria, as well as stratigraphy (percent fine, coarse, total carbonate, oxygen 18 and carbon 13), and geochemistry (percent opal, quartz, and organic carbon), and inferred sea surface temperatures for 635 ocean sediment cores.

Data are primarily from the period 18,000 years bp to the present. Time data give upper and lower sample depths, technique, and C14 dates (for total sample, coarse fraction, and fine fraction). Age estimates are given in thousands of years with upper and lower age error estimates.
