The World Data Center (WDC) for Paleoclimatology, the National Snow and Ice Data Center, and the WDC for Glaciology (Snow and Ice) jointly maintain archives of ice core data from polar and low-latitude mountain glaciers and ice caps throughout the world. Proxy climate indicators include oxygen isotopes, methane concentrations, dust content, as well as many other parameters.
