CORONAVIRUS-19 : SEA NOISE POLLUTION PLUMMETS : GIVES SEA LIFE RESPITE


DAILY MAIL SCIENCE : UNDERWATER NOISE POLLUTION : SEA LIFE RESPITE

EXCERPT:
'We are facing a moment of truth,' marine acoustician Michelle Fournet of Cornell University - who studies humpback whales off of Alaska - told the Guardian.

'We have an opportunity to listen - and that opportunity to listen will not appear again in our lifetime.'

The last time that the oceans fell quiet was in the wake of the terrorist attacks of 9/11, when a reduction in shipping allowed experts to determine that ship noise is connected to chronic stress in baleen whales.

UNDERWATER NOISE POLLUTION CAUSES ACOUSTIC TRAUMA and DEATH


EARTH SKY ORG - UNDERWATER NOISE POLLUTION STRESSES FISH  by  Adam Crane and Maud Ferrari - University of Saskatchewan.  


EXCERPT: Nowadays, the underwater soundscape includes the roar of motors, the ping of military sonar and the bangs and blasts from offshore development.

Communication breakdown...
For fish, whales and other marine animals, intense underwater noises from blasts can cause acoustic trauma and even death. More common quieter noise, such as construction or shipping noise, may not kill the animals directly, but can disrupt their ability to find food and mates, or avoid predators.
