What’s a Testbed?

Super-Regional Testbed – NOAA-RC-2011-03-14

Funded Title:

Super-Regional Testbed to Improve Models of Environmental Processes for the US Atlantic and Gulf of Mexico Coasts

Translated Title:

Make Computer Models that Simulate Processes in Coastal Waters Easier to Use.

The Title Slide..


1Yr - $4 million through NOAA/IOOS to SURA

Program Calendar – May 2010 to May 2011

64 individuals from 20 Universities & 2 Companies

Multi-Agency involvement and benefit

What is the Testbed?


Less about the models than the process. Consensus process for Transition to Ops Value Added… Enable Modeling and Analysis IOOS Subsystem Portfolio

What are the goals of this Testbed?

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

Estuarine HypoxiaChesapeake

Shelf Hypoxia

Gulf of Mexico


“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.”

Where Does the Deep Hypoxic Water Come From?Shelf Hypoxia


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….

Estuarine Hypoxia


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


• 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
