THE SECRET TO A SOUND OCEAN WHALE SOUNDS.

When container ships, oil tankers, and other large vessels travel through waters that are populated by whales, the ships produce noise that disrupts the whales' activities and daily life. emitting mating calls during breeding season. But noise from ships and other human activities in the ocean is disrupting these signals, making it harder and harder for whales to hear.

SHIPS PRODUCE UNWANTED NOISE A noisy ship can interfere with up to 90% of a killer whale's Ocean vessels that travel in whale-populated areas produce background noise that interferes with a whale's acoustic environment. communication.
