In this movie, the viewer starts near the outfall of White Oak Lake, in the Clinch just upstream of Jones Island. This is the outfall which contributes the Cesium contaminant to the river. As the movie proceeds, the viewer is given a bobsled ride, floating 10 feet above the local bottom, all the way to Brashear Island.

The viewpoint is always forward in this animation. The draped colors are again the potential erosion/deposition.

These sequences are the simple results of preliminary experimentation with these tools. Ultimately, as sub-bottom density data arrive from the Army Corps, we hope to interpolate 3-dimensional volumes of sub-bottom sediments, and to visualize these sub-bottom sediments by flying over and through them in ways that would not otherwise be possible. We hope that such visualization tools and techniques will permit and promote intuitive understanding of the data and allow model results to be understood as well. These tools tie the sampling, data, and modeling activities together in a way which may provide new insights.
