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 noise.

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 as they take off ...

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 ...

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 ...

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.
