On the TeraGrid, what is NAVDAT?

Note: After ten years of service to the national science and engineering community, the TeraGrid project has ended. It is succeeded by a new National Science Foundation (NSF) program, the Extreme Science and Engineering Discovery Environment (XSEDE). You should move any data stored on TeraGrid systems to an alternate storage resource. If you have leftover service units on your TeraGrid allocation, or if your research requires further use of high performance computational, visualization, storage, and network resources, consider applying for an allocation on one or more XSEDE digital services.

The North American Volcanic and Intrusive Rock Database (NAVDAT) is an online repository for age, chemical, and isotopic data from Mesozoic and younger igneous rocks in western North America. NAVDAT represents an effort to provide a permanent and publicly available database for existing and new age geochemical data from igneous rocks in western North America. The database allows a continent-wide look at complex space-time patterns of magmatism. Many new visualization tools have been developed for NAVDAT, including space-time animations and time-animated geochemical diagrams. These tools have revealed intriguing new patterns that had not been teased out of the smaller datasets heretofore available, and demonstrate the power of a large, easily accessible database. For more, see the NAVDAT web site.
