Study of marine noise highlights need to protect pristine Australian waters 28-Apr-2021 2:35 PM EDT, by Curtin University
Newswise New Curtin research has found urgent action is needed to ensure man-made underwater noise in Australian waters does not escalate to levels which could be harmful to marine animals, such as whales, and negatively impact our pristine oceans.
Lead author Professor Christine Erbe, Director of Curtin s Centre for Marine Science and Technology, said recent studies from the northern hemisphere showed man-made noise, in particular from ships, often dominates the underwater soundscape over large areas, such as entire seas, and could interfere with marine fauna that rely on sound for communication, navigation and foraging.

Researchers working at the Great Australian Bight have discovered that long-finned pilot whales can mimic the calls of their predators, which may help them to stay alive while they stealthily scavenge.
Key points:
The first study of long-finned pilot whales in the Southern Hemisphere has found the mammals have some surprising vocal abilities
Researchers found vocal similarities to the Northern Hemisphere s pilot whale species
The research raises questions about just how far the animals may be able to travel
