Broadband Used in Ocean Images

FALMOUTH, Mass., April 2 (UPI) — Two advanced broadband acoustic systems will help oceanographers pinpoint tiny zooplankton even in rough seas, scientists in Massachusetts said.

In terms of acoustics, the systems are equivalent to changing from black-and-white television to high-definition color television, researchers at Woods Hole Oceanographic Institution said in a release Thursday.


The systems showed highly promising results when tested recently off the U.S. East Coast, researchers Tim Stanton and Andone Lavery recently wrote in the Journal of Marine Science.

The new systems measure sound scattering over a continuous range of frequencies, rather than just a few frequencies.

The advanced broadband ability will aid oceanographers in classifying fish and zooplankton, no matter the turbulence of the water, Stanton and Lavery said. Previously, it was impossible to know whether sound waves were being scattered by high turbulence or by the objects being studied.
