资源描述【英】 | This data set is provided by the US National Geophysical Data Center. It contains the data files of the CLIMAP (Climate: Long range Investigation, Mapping, and Prediction) project for 18,000 BP, including planktonic counts and core mineralogy. The CLIMAP project was funded by the National Science Foundation as part of the International Decade of Ocean Exploration Program. The CLIMAP 18k bp sediment data files were compiled by Oregon State University. 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. In addition, each data record contains station information. |
