Overview of ResultsOverview of Results

• West Florida Shelf modeling of IOPs and Rrs focused on developing re-locatable, open source code.

• Coupled physical, ecological, optical, and radiative transfer code.– (physics) to EcoSim to Ecolight

• Optical model metrics of validation.

Conclusions and New QuestionsConclusions and New Questions

• Model closure is critical.– Initially described by grazing, but there are significant terms

describing the bottom boundary and regeneration terms that are difficult to close.

• Physical simulation is critical to calculation of ecological/optical simulation model metrics.– See OOXVI LEO 3-D simulations, as well.

• Fresh water fluxes must be considered for this site for < 40 m isobath during periods of high flow.– May not be as important in June, critical in later months.



ResearchInstitute

Conclusions and New QuestionsConclusions and New Questions

• Non-sediment IOPs, CDOM, and chlorophyll modeling appear to be reasonable estimates.– Rrs is not. Why?

• In shore sediment resuspension appears to dramatically impact Rrs in all wavelengths.– Ratio based remote sensing algorithms appear to finesse this

difference.



ResearchInstitute

Status of Data Analysis/Data NeedsStatus of Data Analysis/Data Needs

• Further work on Rrs calculations is required.– Drill down of model coupling and satellite estimates is required.

– Comparison with Spectral Signatures cruise, Oct. 1998.

• Transport of EcoSim code to LEO is complete.– Currently distributed as open source in ROMS 1.8 package.

• Further simulation work on the West Florida Shelf requires the completion and release of ECOHAB data.
