These problems require multidisciplinary research to discover relationships among Earth science disciplines, and depend on the community's ability to construct interoperable geoscience information systems. GEON is developing this cyberinfrastructure for the solid earth sciences to share, link, mediate, and analyze multidisciplinary datasets. The system will enable new interdisciplinary research, store distributed data sets and tools, allow users to search and integrate data not only by name, but by also concepts; and provide high-end computational resources and a customizable analysis and research environment (workflows) for the community.

Approach: The GEON infrastructure is organized into a set of service layers. Dataset search and integration are enhanced via ontologies. This requires semantic data registration, i.e., information about GEON-registered data sets, ontologies, and their linkages are stored in a GEON repository. The GeoWorkbench builds upon scientific workflow technology for complex analysis pipelines that bring together data access, querying, and general computational steps. Visualization and mapping services can be realized both through open source as well as commercial tools. GEON is a TeraGrid application and jobs submitted through the portal can be run on the Grid.

Significant Results:

• GEONgrid is online: ROCKS compute and data nodes (DB2, SRB, ArcInfo, …), currently 13 sites including 4 clusters• GEON portal online (GridSphere, JSR-168 compliant portlets)• Dataset registration system, including ontology registration • Ontology-enhanced search and data integration• Geologic map integration system • Concept-based queries and analysis• Scientific workflow technology (Kepler)• Joint community & IT/KR based ontology building • Cross-project collaborations (BIRN, SEEK, SCEC, …) • Industry collaborations (ESRI, IBM, … )• coming soon: 1Gbps UCSD NASA Goddard (via OptIPuter)

Broader Impact: GEON caters primarily to the needs of the solid earth geosciences community and will enable scientists to share and data and computational resources for new and interdisciplinary research. GEON technologies will also be usable by other communities due to a standards based, open system architecture. An education and outreach program (e.g., joint Geo/IT workshops; planned summer institutes etc) brings GEON technology and results to a wider community .
