Dr. Lutz shares breathtaking photos and video clips in his explanation of biological and geological changes he has observed at an undersea volcanic ridge 2,500 meters deep in the Pacific Ocean. Dr. Lutz's ongoing studies of this unique, natural deep-sea "laboratory" are dramatically altering our views of the rates at which many biological and geological processes are occurring on the face of the planet. **Dr. Lutz** served as Science Director for the IMAX film Volcanoes of the Deep Sea.
