In acidic oceans, sound carries further
Darkfrog submitted, created time 3 months 1 week (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. 


Marine biologists interpret whale sounds

The splashes, barks and grunts of baleen whales carry much more meaning than biologists thought, according to the latest survey of the marine mammals.
The scientists behind the study say that these noises could be the ideal characteristics for conservationists to monitor to understand the growing impact of noises made by humans on the underwater environment.

Once hunted to the brink of extinction, humpback whales have made a dramatic comeback in the North Pacific Ocean over the past four decades... 
Arctic warming poses risks to narwhals

The polar bear has become an icon of global warming vulnerability, but a new study found an Arctic mammal that may be even more at risk to climate change: the narwhal, which is a whale with a long spiral tusk that inspired the myth of the unicorn, edged out the polar bear for the ranking of most potentially vulnerable in a climate change risk analysis of Arctic marine mammals. 
Whales may have evolved from raccoon-sized creature

In the search for a missing evolutionary link to modern whales, scientists have come up with an unlikely land cousin -- a raccoon-sized creature with the body of a small deer. 
Long-Lost Relative of Whales Found?

A group of paleontologists has identified what they believe is the closest relative of whales, dolphins, and porpoises--an extinct, raccoon-sized creature that sloshed along river bottoms and could have eaten like a landlubber. The find promises to give scientists a better idea of where whales and their ilk came from.

The Cuvier's beaked whale is a master of the ocean's crushing depths. It can dive as deep as 2 kilometers in search of prey, the deepest known for any mammal. So scientists have been at a loss to explain why, in response to naval sonar testing, this champion cetacean sometimes succumbs to the same decompression sickness that afflicts scuba divers. A new mathematical model suggests that, by replicating the sounds of a predator, sonar forces the whale to adopt a risky diving pattern. 


Marine worms chow down on cow bones

Weird whale-bone eaters can survive on more than just whale. Now it seems that several species of the Osedax worm can dine on cow carcasses as well.

"Two humpback whales that made a 90-mile river journey from San Francisco to the outskirts of Sacramento have injuries that appear to have come from a propeller, marine experts announced Wednesday."
