Dear MARMAM community,

My co-authors and I are pleased to share our new publication in
Communications Biology:

Trickey, J.S., Cárdenas-Hinojosa, G., Rojas-Bracho, L., Schorr, G.S., Rone,
B.K., Hidalgo-Pla, E., Rice, A., & Baumann-Pickering, S. Ultrasonic
antifouling devices negatively impact Cuvier’s beaked whales near Guadalupe
Island, México. Communications Biology 5, 1005 (2022).

Widespread use of unregulated acoustic technologies in maritime industries
raises concerns about effects on acoustically sensitive marine fauna
worldwide. Anthropogenic noise can disrupt behavior and may cause short- to
long-term disturbance with possible population-level consequences,
particularly for animals with a limited geographic range. Ultrasonic
antifouling devices are commercially available, installed globally on a
variety of vessel types, and are marketed as an environmentally-friendly
method for biofouling control. Here we show that they can be an acoustic
disturbance to marine wildlife, as seasonal operation of these hull-mounted
systems by tourist vessels in the marine protected area of Guadalupe
Island, México resulted in the reduced presence of a potentially resident
population of Cuvier’s beaked whales (*Ziphius cavirostris*). Human
activities are rapidly altering soundscapes on local and global scales, and
these findings highlight the need to identify key noise sources and assess
their impacts on marine life to effectively manage oceanic ecosystems.
