Noisy oceans potentially driving whales away from prime habitat
A new report from WWF details the problems increasingly noisy oceans are creating for whales. Those problems include finding mates, finding food, and potentially driving whales away from prime habitat.
Marine life gets drowned out as oceans get noisier
A PhD student from the Department of Physics who recently returned from a trip to lay microphones on the ocean floor off the west coast of Canada is warning of the dangers to marine life from increased ocean ...
Researchers seek to reduce ear-splitting jet engine noise
Have you ever had a fighter jet fly over your home and the noise of the aircraft booms loud enough to rattle the windows? Well, imagine working on an aircraft carrier or air base, up close to the engines ...
Tropical cyclone waves detected with infrasound sensor array
The strong winds of a tropical cyclone whip up the sea surface, driving ocean waves a dozen meters (about 40 feet) high. When one such ocean wave runs into another wave that has an equal period but is traveling in the opposite ...
URI oceanography student uses crashing waves on shorelines to study Earth's interior
Scientists have long used the speed of seismic waves traveling through the Earth as a means of learning about the geologic structure beneath the Earth's surface, but the seismic waves they use have typically been generated ...
SMOS measures ocean salinity, provides complete view of ocean every 5 days
(Phys.org)—Earth observation measurements shouldn't be taken with a pinch of salt. ESA is comparing readings of sea-surface salinity from drifting floats to confirm the SMOS water mission's measurements.
Homing in on a potential pre-quake signal
In a new analysis of the 2004 magnitude 6.0 Parkfield earthquake in California, David Schaff suggests some limits on how changes measured by ambient seismic noise could be used as a pre-earthquake signal.
Blue whale behavior affected by man-made noise: study
Blue whale vocal behavior is affected by man-made noise, even when that noise does not overlap the frequencies the whales use for communication, according to new research published Feb. 29 in the open access journal PLoS ON ...
Ocean cacophony a torment for sea mammals
With the constant churn of freighter propellers, the percussive thump of oil and gas exploration and the underwater din of military testing, ocean noise levels have become unbearable for some sea mammals.
Gravitational waves that are 'sounds of the universe'
Einstein wrote about them, and we're still looking for them -- gravitational waves, which are small ripples in the fabric of space-time, that many consider to be the sounds of our universe.
Baby corals dance their way home
(PhysOrg.com) -- Baby corals find their way home in their first days as free-swimming larvae by listening to the noise of animals on the reef and actively swimming towards it, an international team of researchers ...
Sound maps reveal whales and noise pollution
(PhysOrg.com) -- Chris Clark discussed his state-of-the-art acoustic animations and the difficulties facing whales Feb. 21 at the American Association for the Advancement of Science annual meeting in San Diego.
