In acidic oceans, sound carries further
Darkfrog submitted, created time 2 months 1 day (sciencenow.sciencemag.org)
It seems that as the oceans grow more acidic with all this atmospheric CO2, sounds begin to travel longer distances before they dissipate. Despite what one might think, this is not good news for whales and dolphins, which use sound to communicate and travel. Military sonar can already disrupt cetacean behavior as much as five hundred kilometers away. If things continue at the current rate, then by 2050, these sounds will travel 70% further in some parts of the Atlantic.
