GEONGEON
NSF Large ITR project – collaborative effort GEON is creating an IT infrastructure to
“enable” interdisciplinary geoscience research for the entire community
Project started in October 1, 2002 (after three years of preparation) and will continue
until September 30, 2007

GEON’s Vision
• Enable new discoveries in the geosciences by utilizing an easy-to-use “integration environment” built using state-of-the-art information technology resources.
The end product is a system that :Enables new interdisciplinary research and encourages resource sharing Stores and seamlessly integrates distributed data sets, software, and toolsAllows users to make searches to discover data and information
not only by name, but also by concepts.Provides high-end computational resourcesProvides a customizable analysis and research environment (workflow)Is a rich resource for teachers and learners

GEON Cyberinfrastructure Principles
• An equal partnership • IT works in close conjunction with science
• CI: Support the “day to day” conduct of science (e-science), in addition to “hero” computations
• The “two-tier” approach• Use best practices, including use of commercial tools and open
standards, where applicable…• …while developing advanced technology, and doing CS research
• Create shared “science infrastructure”• Integrated online databases, with advanced search and query engines• Online models, robust tools and applications
• Leverage from and work with other intersecting projects• Much commonality in the technologies, regardless of science
disciplines, e.g. BIRN, SEEK, and many others
