Noise from ships impedes humpback whales from foraging for food, and could have long-term impacts on the health of the giant marine mammals, according to a study released Wednesday. Shipping lanes overlapping with the coastal migratory paths of whales create a steady source of underwater noise pollution. Earlier research has shown how this can interfere with the behaviour of so-called toothed whales — a category that included dolphins, as well as killer and sperm whales — that emit sonar-like pings to locate prey and communicate.
