Orcas Continue Attacks on Boats Despite Heavy Metal Deterrent

Scientists warn that underwater music could harm marine life and contribute to ocean noise pollution.

Orcas have been increasingly attacking boats off the coasts of Spain and Portugal since 2020, with some incidents resulting in the sinking of vessels.
Sailors have attempted to deter the orcas by blasting heavy metal music underwater, but this method has proven ineffective and potentially harmful.
Andrew Trites, director of the Marine Mammal Research Unit at the University of British Columbia, warns that loud underwater music could cause pain and hearing damage to orcas and contribute to ocean noise pollution.
Scientists are unsure of the exact reason for the orca attacks, but theories include a defensive response from a female orca harmed by a boat, or simply playful behavior.
Efforts to find effective deterrence methods are ongoing, with recommendations for sailors including maintaining a low profile, keeping a firm grip on the boat, and waiting until the orcas leave the area before resuming sailing.
