A high tech sound system hopes to keep whales from deadly collisions with ships

Around 80 whales are killed by cargo ships on the West Coast of the United States each year.

However, scientists at UC Santa Barbara are now looking to technology to help curb the whale strikes. The underwater sound system in the Santa Barbara Channel picks up on whale sounds and enables scientists to warn cargo ships that they are getting close to whale pods.

“No company wants to cruise into the Port of Los Angeles with an endangered species stuck to the front of its ships,” said Douglas McCauley

The listening station sponsored by the Benioff Ocean Initiative is stationed 650 feet below water near the coast of Santa Cruz Island and is able to capture whale calls as far away as 30 miles and then transmits whale sound data by satellite to scientists onshore. 

“This is the first real-time whale detection system anywhere in the Pacific ocean,” said McCauley. “And we are well-overdue for pulling this technology in.”  

When whales are present, cargo ships are alerted to slow down. Reducing their speed greatly reduces the risk of striking and killing the animals.
