COVID Silver Linings: Ocean Noise

Reduced ship traffic is yet one more way wildlife–marine mammals, especially whales in this case–is benefitting from the global pandemic lockdown:

“We have a generation of humpbacks that have never known a quiet ocean,” said Fournet, whose work has shown that the whales alter their calling behaviour in response to a noisy ocean.

Late April usually marks the beginning of the cruise ship season in south-east Alaska, with the boats docking at Vancouver before heading north. This year the health crisis has halted them.

“What we know about whales in south-east Alaska is that when it gets noisy they call less, and when boats go by they call less,” said Fournet.

“I expect what we might see is an opportunity for whales to have more conversation and to have more complex conversation.”

Long may it last.
