DATA ------------

This is a new and somewhat experimental page dedicated to posting databases (isotopic, geochronological, paleomagnetic, etc.) pertinent to Neoproterozoic glaciations and Earth history. The intent is to make these data available in an easy-to-access and easy-to-use format, or at the very least, provide a single website that can direct users to these databases. I will begin by posting the link to the data used to construct the composite d13C record in Halverson et al. (2005), as well as an updated database to published in a forthcoming Kluwer special volume (Eds. S. Xiao and A.J. Kaufman). Anyone wishing to post a database or with input on how to organize this page should feel free to contact me at halverson*igcp512.org.
