Motivation for a Prototypical Chesapeake Bay Environmental Observatory 1.Management Needs are Linked with Science Water quality impairment and loss of living resources 2.Wealth of Data, Models and Research Archived data; on-going data streams; history of model runs 3.Important Unresolved Questions Complex questions of broad national interest (e.g., hypoxia) 4.Clear Need for Better Cyberinfrastructure Disparity among data & lack of inter-operability stymies progress 5.Excellent Test Bed for EO Integration other EONs; research & education programs; outreach

Hypoxia An Excellent Problem for EO and Cyberinfrastructure Fundamentally linked to other concerns: -- Affected by land use, water quality, hydrodynamics, biota; -- Affects chemical cycling and living resources Well-studied issue, but with complex unresolved questions: -- Non-linear O 2 responses to management & climate -- Missing source of organic matter to fuel hypoxia A Prototypical Science Issue Relevant to environmental management in many aquatic systems; Long history of policy and management focused on D.O. Requires linking data-sets & models; Requires multiple observing & computing systems; Involves multiple spatial & temporal scales; Identifiable management benefits via modeling and visualization. Strong Links with Engineering & Management

Questions?

Hypoxia vs. N Loading ( ) (Hagy et al. 2004) Hypoxia increases with N loading. Equivalent N loading in recent years (since ‘80) generates more hypoxia than in past. Winter-Spring NO 3 - Loading (10 6 kg) Hypoxic Volume (10 9 m 3 ) (DO<1 mg l -1 ) Unresolved Science Questions

Serve as a node in a larger EON grid structure to demonstrate the ability of CI to facilitate shared use of data, data streams, model, and tools; Develop and demonstrate new tools and approaches for linking research with education and public policy. Be a test-bed for the development, demonstration, and dissemination of new cyberinfrastructure tools; Transform science and engineering research by providing nationwide access to and interoperability among data sets, model results, model applications, analytical tools and data streams (existing and future) in the nation’s largest estuary.
