Tomographic transmissions consist of long coded signals lasting 30 seconds or more. With precise timing, travel times can be measured to a nominal accuracy of 1 millisecond. These transmissions are audible near the source, but over most of the ocean they are below ambient noise levels, requiring sophisticated Spread-spectrum Signal Processing techniques to recover them. Many of the tools and techniques for ocean acoustics tomography originated in Ocean Acoustics Lab at the Woods Hole Oceanographic Institution . EXTERNAL LINKS
