CBEO:N Chesapeake Bay Environmental Observatory as a Network Node

1. CBEO:N Chesapeake Bay Environmental Observatory as a Network Node About CBEO CBEO Network Node in GEON Grid CBEO Node in CUAHSI HIS • The mission of the CBEO project is development of a Chesapeake Bay Environmental Observatory as a prototype of cyberinfrastructure (CI) for environmental observatory networks (EONs) demonstrating the transformative power of CI. • The project is organized around the following four concurrent and interacting activities: • CBEO:N incorporates the test bed CI into the national EONs • by constructing a GEON-based node and a CBEO web portal • by developing a CUAHSI-HIS-based node, available under the same portal • by prototyping CBEO tools that can be re-used through the portal • CBEO:E is the education and outreach element, with the mission to translate observational science for public consumption • MAST: Multicultural students At Sea Together, Hampton U. • Field Courses, Science Workshops • (3) CBEO:T constructs a locally accessible CBEO test-bed prototype • managing 10 years of Chesapeake Bay water quality and hydrodynamics model • CIMS, MD DNR, overflightchl-a • spatial indexing for cross-data set queries • (4) CBEO:S provides science, engineering, and management research context for various cyberinfrastructuretools and techniques • focus on hypoxia in Chesapeake Bay, in particular non-linear O2 responses to management and climate; effects of land use, water quality, hydrodynamics, biota, etc. HIS Server for Chesapeake Bay is available through the CBEO portal Hydroseek is also available through the portal, as part of “CBEO Tools” http://geon16.sdsc.edu:8080/gridsphere CBEO Data and Tools Resolving metadata heterogeneity Multiple registered resources, including shapefiles, spreadsheets, Relational databases, documents. • Aligning ODM schema with the 10year model run schema: would be CBEO contribution to national network • We have an ODM-2 proposal; ODM has a set of core tables, and extension tables or pointers to external sources (e.g. pointing to NetCDF) • Need a NetCDF converter for the testbed data • Presenting grid cells via external feature services, or preferably, WCS (WCS spec allows this, but n implementations…) • How generic is the data values part of the schema, and the grid cell characteristics?? • ODM is exposed via web services; what are the use cases for the model data so that we can design service signatures?? An R-based interpolator developed by Rebecca Murphy from JHU,is exposed via the portal
