(Credit: NASA/ Earth Observatory) In December, a team of researchers and students at the University of California, Santa Barbara made the best of a local tragedy. The Thomas Fire, the largest in the state’s history, burned nearly 300,000 acres (120,000 hectares) in Ventura and Santa Barbara counties north of Los Angeles. The smoke [...]

To the perceptive ears of killer whales, those same ships might have sounded a little bit quieter. (From Oregon [...]

(From Eurekalert.org) -- The study, which is featured on the cover of the January 2018 issue of the Journal of General Physiology, explains how the [...]

(From Phys.org) -- From the metallic clicks of deep-diving sperm whales to the eerie whistles made by pods of [...]
Atlantic Cod (Credit: NOAA) NOAA scientists studying sounds made by Atlantic cod and haddock at spawning sites in the Gulf of Maine have found that vessel traffic noise is reducing the distance over which these animals can communicate with each other. As a result, daily behavior, feeding, mating, and socializing during critical [...]
New acoustic analysis could pinpoint impacts by meteorites or possibly plane debris. The ocean can seem like an acoustically disorienting place, with muffled sounds from near and far blending together in a murky sea of noise. Now an MIT mathematician has found a way to cut through this aquatic cacaphony, to identify underwater sound waves generated by objects impacting the ocean’s surface, such as debris from meteorites or aircraft. The results are published this week in the online journal Scientific Reports.
Humpback whales have a trick or two when it comes to finding a quick snack at the bottom of the ocean. But how they pinpoint that meal at night, with little or no available light, remains a mystery.
A central question in the debate over a Rutgers University-led study of the ocean floor off the coast of Long Beach Island is whether the loud sound waves used to map the sediment will harm dolphins, whales, and other animals.
A Rutgers study that would aim sound blasts deep into the ocean floor off the New Jersey coast to study sea-level changes from as long as 50 million years ago has passed its final regulatory hurdle.
While captive in a Navy program, a beluga whale named Noc began to mimic human speech. What was behind his attempt to talk to us?
