  1. Conceptual Design of aChesapeake Bay Environmental Observatory (CBEO) A Collaborative Planning Project funded by the NATIONAL SCIENCE FOUNDATION CHESAPEAKE RESEARCH CONSORTIUM Tom Gross (Chesapeake Community Modeling Program) JOHNS HOPKINS UNIVERSITY Bill Ball (Dept. of Geography & Environmental Engineering) Randal Burns (Dept. of Computer Science)UNIVERSITY of DELAWARE Dom DiToro (Dept. of Civil & Environmental Engineering) UNIVERSITY of MARYLAND Mike Kemp (Center for Environmental Science) DREXEL UNIVERSITY Mike Piasecki (Dept. of Civil & Architectural Engineering) SAN DIEGO SUPERCOMPUTER CENTER Ilya Zaslavsky

  2. Motivation for a PrototypicalChesapeake Bay Environmental Observatory • Management Needs are Linked with ScienceWater quality impairment and loss of living resources • Wealth of Data, Models and Research Archived data; on-going data streams; history of model runs • Important Unresolved Questions Complex questions of broad national interest (e.g., hypoxia) • Clear Need for Better CyberinfrastructureDisparity among data & lack of inter-operability stymies progress • Excellent Test Bed for EO Integrationother EONs; research & education programs; outreach

  3. Hypoxia • A Prototypical Science Issue • 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 • Strong Links with Engineering & Management • Relevant to environmental management in many aquatic systems; • Long history of policy and management focused on D.O. • An Excellent Problem for EO and Cyberinfrastructure • Requires linking data-sets & models; • Requires multiple observing & computing systems; • Involves multiple spatial & temporal scales; • Identifiable management benefits via modeling and visualization.

  4. Chesapeake Watershed Chesapeake as Test Bed for EO Integration Mid-Atlantic Environmental Observatories: MAREO (NEON) Susquehanna River Hydrologic Observatory (CUAHSI / WatERS) Potomac River & Western Tributary Hydrologic Observatory Baltimore LTER/CLEANER Chesaspeake Bay Observing System (CBOS) CBEO (CLEANER/WatERS) York River ORION from K. Selner, CRC (ERF 2005)

  5. Environmental Observatories:Four Parallel and Interactive Activitiesfor 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 EO:N EO:E EO:T EO:S

  8. 3. Unresolved Science Questions 1950-1969 1980-1989 1970-1979 1990-2001 12 10 8 Hypoxic Volume (109 m3) (DO<1 mg l-1) 6 4 2 0 10 15 20 25 30 35 Winter-Spring NO3- Loading (106 kg) Hypoxia vs. N Loading (1950-2001) • Hypoxia increases with N loading. • Equivalent N loading in recent years (since ‘80) generates more hypoxia than in past. (Hagy et al. 2004)

  10. 2. Wealth of Data, Models and Programs (cont’d) Chesapeake Bay Monitoring Program • Extensive data collection • --Fixed station monitoring @ 2-4 wk • --Research data at finer spatial scales • CBP monitoring @ ~50 stations in • mainstem Bay plus many more in tribs • Vertical profiles in deep & shallow water • CBP monitoring initiated in 1985 • through present with few changes • CBP monitoring data available on web • Monitoring focuses on deep channels, • & extensive shallows under-sampled

  11. 2. Wealth of Data, Models and Programs (cont’d) Dissolved oxygen and Chlorophyll-aDerived from transects taken using a vertically undulating sensor system (Scanfish)(Kemp, 2005)

  12. Conclusions (2) A Chesapeake Bay Environmental Observatory would: • 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.
