Shipping lanes are getting too noisy for the whales, coastal survey shows

Humpback whales and killer whales are losing up to 94 percent and 97 percent, respectively, of their communication space in the busiest areas of the ocean off the British Columbia coast, according to a new study.


Shipping noise is an easy problem to fix, compared with acidification, a warming climate and other situations that would take decades to address, Williams added. To cut down on the cacophony, ships could slow down or avoid whale-filled areas, or manufacturers could construct quieter vessels, he suggests.
