The researchers are developing a modeling framework that integrates hydrodynamic circulation models and various biological models with the computer visualization paradigm of the virtual world to investigate coupled linkages between physics, biology, and societal pressures within the Chesapeake Bay ecosystem. Their results show how environmental forcing affects the flow in the Chesapeake Bay and also demonstrate how biological distributions change in response to the circulation in the Bay.

Using interactive visualization, one can visually compare various physical fields in the 3D space occupied by the Earth's atmosphere and oceans, and their time dynamics can be examined at coarse or fine time resolutions. Interactivity is essential because it allows scientists to choose which combinations of fields to view and at what spatial and temporal locations and scales, based on data content.

Ocean circulation and ocean thermal and density structures are inherently 3D, time-dependent phenomena. Scientific insight is quantitatively and qualitatively improved by being able to visualize such datasets and computer simulation experiments in a true 3D, time-dependent, and interactive environment.

Using this virtual reality porous media simulation, scientists and engineers can visualize contaminant and water saturations together with soil permeabilities in three dimensions. Investigators can add wells to extract contaminants and air lines to modify subsurface pressures to test the efficacy of different recovery methods.
