Motivation
• Numerical models play an ever increasing role
in Oceanographic research
• Most models are of such complexity that they
are out of reach as teaching tools
• At the same time, the basic concept of
numerical modeling is an ideal paradigm for
teaching
Target audiences
• Formal education: K-12, undergraduate, and
graduate education
• Informal Education: Science museums
• Resource managers
Method
• Take a standard, open source numerical
model and apply it to a particular system
• Allow user to control forcing of model and
data display through a Graphical Front
End
• Pare down model so that speed of
execution is fast enough that casual user
find it interesting, but still retains physical
fidelity
Technical details
• Numerical model: the Regional Ocean Modeling
System (ROMS), available from the IMCS at
Rutgers University. F90 code

50x20 curvilinear masked grid, 10 vertical levels
Salt, no temperature
Tides imposed at offshore boundary
Allows user to modify wind field, freshwater flux
Allows user to choose V, S, sfc height, drifters
• Front End: C++, using the Fast Light Toolkit
Why use a “real” model?
• While this is a kludgy approach to the
problem, it allows us greatest flexibility in
the long run
• Allows for porting of model to other
geographic domains
• Incorporation of submodels (biology,
chemistry, sediments, etc)
• Large user community
Let’s see it!
Future improvements
• To Forcing:
– Incorporate basic biological model
– Incorporate land-use models
– Port to different geographic regions
• To output:
– Allow user to place “moorings”, developing
time series
• Currently have proposal to SeaGrant to
build “Modular” system
