Paleoceanography data are derived from many proxies found in deep-sea sediments including trace metal and isotopic composition of fossil plankton, species composition, and lithology. The World Data Center (WDC) archives data for all times in the past. You are likely to find data relevant to thePast Global Changes (PAGES) and PAGES-CLIVAR timescales in our relational database, while data for older geologic times (more than 1 million years before present) will be found only in the by contributor directory of our FTP site. Coral and mollusk data are archived in their own sub-directories.
