SU biologist develops method for monitoring shipping noise in dolphin habitat
Date:12/2/2013

the research lab of Professor Susan Parks, a specialist in the ecology and evolution of acoustic signaling. "The cumulative effect of many noisy ship passages can raise the physiological stress-level of marine mammals and affect foraging behavior."

Due to a lack of reliable baseline data, Merchant and his collaborators at Aberdeen have figured out how to monitor underwater noise levels, using ship-tracking data and shore-based time-lapse photography. These techniques form a ship-noise assessment toolkit, which Merchant says may be used to study noise from shipping in other habitats.

Parks, for one, is excited about Merchant's accomplishments. "Nathan has been a great addition to our lab," she says. "His strengths in signal processing and noise measurements for ship noise have expanded our capabilities. Underwater noise is a global problem, as major shipping routes connect all of the economies of the world."
