Inundation Successes
• Grids, forcing, and observational data for specific storms are being shared for community testing.
• Direct comparisons are being made between operational inundation models and academic community models.
• Community building by modeling groups. Working together, sometimes for the first time….
• Improved academic - government partnerships

“Reduce uncertainty about the relationship between nitrogen and phosphorus loads and the formation, extent,, duration, and severity of the hypoxic zone, to inform adaptive management.”

Picture of Nepheloid
Early “Insights” into the “Deeps”…
Summer near bottom residence > 4 months Most near bottom water tracks near the shelf-break
Filament structures are observed in the flow
Along track variations in oxygen are observed
There may be no “source” of hypoxic bottom water. Hypoxia may happen to water that is already there….

Hypoxic Volume from Simple (1-term) vs. Complex (ICM) Models
Hypoxia in Chesapeake Bay
• Simple 1 term model for DO reproduces seasonal variability in hypoxic volume about as well as complex watershed + water quality model.
• Only weak correlation between DO and stratification
– DO is not highly sensitive to changes in freshwater inflow
• Extent of hypoxia zone is strongly related to wind direction –
• North Atlantic Oscillation?

Hypoxic Volume Increases in 1985 Nitrate Load decreases from 1970’s
Flow Average Increases Slightly
Hypotheses – Is Hypoxia correlated with NAO?

CONOPS for R2O
Super-Regional Testbed – NOAA-RC-2011-03-14
• The model must meet a demonstrated need.
• The model results must be timely and reliable.
• The model results must be “more correct”, showing decreased uncertainty.
• The model must be useable, incorporating standardized terms and formats
• The Operational Center must establish a dialog with the modelers.
• Resources needed for transition must be identified.

What’s in the Testbed Future?
• Expand to more regions & more coastal issues
• Examine more factors (e.g. data assimilation approaches, model coupling)
• Build out the cyberinfrastructure (more functionality, toolboxes for other languages, web services, outreach, training)
• Find a way to sustain testbed activities
