Students in a bioacoustics workshop partly run by WHOI scientists Peter Wiebe, Tim Stanton, and Gareth Lawson in July 2013 at Friday Harbor Laboratories watch as a towed sonar system is deployed from the research vessel Centennial. The sonar system, made by BioSonics, Inc. of Seattle, carries two downward-facing transducers that emit sounds at different frequencies. Reflections of the pings can be analyzed to discern the type of organisms in the water and their depth. (Photo by Peter Wiebe, Woods Hole Oceanographic Institution)
