ABSTRACT
Chesapeake Bay is one of America's most productive, commercially important, and threatened ecosystems. The gradual and steady urbanization of the surrounding watershed has harmed the Bay's ecosystem. We describe our efforts to develop the Chesapeake Bay Virtual Environment (CBVE)-a multidisciplinary, collaborative project that fuses 3D visualizations of numerically generated output, observations, and other data products into a large-scale, interactive virtual world. CBVE has already proved useful in the scientific investigation of how physical and environmental processes affect circulation in the Bay as well as how this variability influences transport pathways and residence (retention) times of selected ecosystem components. Our ultimate product will incorporate runtime computational steering, interactive visualization, data sonification, and wide-area information dissemination capabilities. The development and implementation of our application to date has been supported by use of the SGI Power Challenge Array located at the National Center for Supercomputer Applications (NCSA) as well as the Information Wide Area Year (I-WAY) and the Global Information Infrastructure (GII) Testbed constructed for Supercomputing 95.
