Conceptual Design of aChesapeake Bay Environmental

Observatory (CBEO)

A Collaborative Planning Project funded by the

NATIONAL SCIENCE FOUNDATION

Motivation for a PrototypicalChesapeake Bay Environmental Observatory

1. Management Needs are Linked with ScienceWater 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 CyberinfrastructureDisparity among data & lack of inter-operability stymies progress

5. Excellent Test Bed for EO Integrationother 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 O2 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

Mid-Atlantic Environmental Observatories:

Environmental Observatories: Four Parallel and Interactive Activities

for Prototype Development

N – develop a Node on a national network system to ensure compatibility within a broader EON

E – develop links and programs for Education, outreach, and widespread use of the EO

T – build a Test-bed for the development anddemonstration of technical tools

S – develop and explore the Science, engineering & management issues

Questions?

Hypoxia vs. N Loading (1950-2001)

(Hagy et al. 2004)

• Hypoxia increases with N loading.

• Equivalent N loading in recent years (since ‘80) generates more hypoxia than in past.

2. Wealth of Data, Models and Programs (cont’d)

• Serve as a node in a larger EON grid structureto demonstrate the ability of CI to facilitate shared use of data, data streams, model, and tools;

• Develop and demonstrate new tools and approachesfor 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 amongdata sets, model results, model applications, analytical tools and data streams (existing and future) in the nation’s largest estuary.
