Visualization of Ocean Floor Bottom and Earthquake Fields in the Macquarie Ridge Complex
	Dr. Mike Coffin and Timothy Meckel of UT's Institute for Geophysics and Reuben Reyes of TACC are visualizing large 3D data sets in an immersive environment to study ocean floor bottoms and earthquake fields in the Macquarie Ridge Complex. The Macquarie Ridge Complex is half a world away located between Australia and Antarctica, but the Visualization lab allows researchers to safely explore ocean trenches 6.5 kilometers deep, correlate earthquakes with ocean tectonic plates, and view earthquake fields under the ocean floor. Ocean floor bottoms were made into 3D models from multibeam sidescanning sonar and the earthquake foci were represented as spheres to create an earthquake field that dates from years 1929 to 2000.
