Ecosystem Explorer for NOAA shows a more nuanced version of the standard food chain. The idea is to go beyond simple predator/prey relationships to show the ecosystem as a coherent whole, and explore the way energy (as biomass) moves through it. This is a preliminary interface, aimed at high school, early college, and the general public. There will eventually be modules targeted more towards specialists, to tame the wealth of data: currents, weather patterns, microclimates at certain locations and depths, external inputs such as fertilizer runoff, the propogation of events (such as hurricanes) through the bay, and so on. It's a great target for visualization, both because of the formal richness of the data (many dimensions etc) and the fascination of the material.
