Human-made underwater noise is filling those channels with sound from commercial or recreation vessels, in- or near-water construction like dredging or pile driving, seismic surveying, and active sonar.
New research now suggests human-made ocean noise is more harmful to marine life than we realised. In a study published in the journal Science, a global research team including University of Victoria biologist Francis Juanes set out to document the impact of noise on marine animals and on marine ecosystems around the world.
