The Chesapeake Interactive Modeling Project

Minnesota Sea Grant has decided to fund the next round of development of our modeling tools. In the previous round, supported by the State of Virginia, we developed the CHIMP- Chesapeake Interactive Modeling Project. THis pilot project was a "proof of concept", showing that a front end could be built that ran fast enough to be interesting to a casula user but still reproduced the basic physical features of circulation in an estuary.

In this coming round, we intend to develop a much more flexible product, which will be adaptible to a wide variety of scenarios. In addition, we are funded to develop classroom tools to help instructores in tegrate the tool into their Earth Science lesson plans.


If you download this product and decide to use it, no matter how briefly, please let me know! I am very interested in tracking its use, especially in classroom settings. Any feedback you might have about its use is equally appreciated.

There appear to be some problems with the graphics on older windows machines. If text doesn't show up, or the land mask doesn't show up on your computer, let me know.


The Chesapeake Interactive Modeling Project (CHIMP) was a short pilot program sponsored by the State of Virginia. The purpose of the project was to develop a pilot software product which could be used in a classroom setting to teach about the basic characteristics of circulation in the Chesapeake Bay, by allowing a user to change the wind speed and velocity, and the freshwater forcing through a number of subestuaries, and observe the resulting surface height, circulation and hydrographic structure in real time. At its core, CHIMP uses ROMS, the Regional Oceanic Modeling System, a research-grade numerical model used by oceanographic researchers worldwide. It incorporates a graphical front end to make this complex model accessible to a much wider audience.
