Scientists hope to use images like these to assign a unique acoustic signature to an ecosystem. (sciencemag.org)
When the beams cross inside the object, they create precise interference patterns that provide acoustic signatures needed to construct a clear 3 - D image of internal structures throughout the scanned area. (caltech.edu)
If Mayer and his colleagues can find a reliable acoustic signature of underwater oil, they say researchers will be able to map the spread of plumes using sonar aboard ships cruising at 10 knots. (sciencemag.org)
