Experimental wave-power buoy survives winter in Monterey Bay
In early January 2015, a team of MBARI engineers, led by Andy Hamilton, set out to sea to recover an experimental buoy that creates electrical energy from ocean waves. This power buoy had been deployed six ...
Study examines role of acoustic-gravity waves as ocean transport, early warning of tsunamis
Acoustic-gravity waves—a special type of sound wave that can cut through the deep ocean at the speed of sound—can be generated by underwater earthquakes, explosions, and landslides, as well as by surface ...
Better forecasts for sea ice under climate change
University of Adelaide-led research will help pinpoint the impact of waves on sea ice, which is vulnerable to climate change, particularly in the Arctic where it is rapidly retreating.
Rocky platforms dissipating wave energy – a new option for coastal defence?
Communities across Wales are coming to terms with the very real threat of coastal flooding as the Welsh Government announces that as many as 48 areas have been identified where coastal defences will not be maintained in the ...
Small islands may amplify tsunamis
Small islands, long thought to be natural tsunami barriers for coast-dwellers, may in fact amplify the waves they are supposed to break, researchers warned Wednesday.
Studies in laser physics help understand rogue waves
(Phys.org) —University of Auckland physicist Dr Miro Erkintalo is part of an international team investigating how lasers and optical fibres can be used to understand freakishly large waves on the ocean.
The Fickle El Nino of 2014
Prospects have been fading for an El Niño event in 2014, but now there's a glimmer of hope for a very modest comeback. Scientists warn that unless these developing weak-to-modest El Niño conditions strengthen, ...
Two solar particle blasts could start smacking into Earth Friday
Bim, bam, smash! The Sun hurled two clouds of particles in our general direction, putting space weather watchers on alert. There's now a high chance of auroras on Sept. 12 (Friday), according to the National ...
NASA helps harness an ocean of energy
NASA is helping the U.S. Department of Energy (DOE) harness the power of the oceans by first harnessing the power of the crowd.
Climate change: meteorologists preparing for the worst
Intense aerial turbulence, ice storms and scorching heatwaves, huge ocean waves—the world's climate experts forecast apocalyptic weather over the coming decades at a conference in Montreal that ended Thursday.
Huge waves measured for first time in Arctic Ocean
As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water which is predicted to extend across the whole Arctic Ocean before the middle ...
Judge says ocean sound blasts need not be halted
A federal judge says he will not grant New Jersey's request to halt federally funded scientific research that includes blasting the ocean floor with sound waves.
New Jersey asks judge to block ocean blasting plan
New Jersey environmental officials went to federal court Thursday trying to block a federally approved research plan that involves blasting the ocean floor off New Jersey with loud sound waves.
Directionality of crystal elasticity offers explanation for variable seismic character of the inner Earth
Seismic studies enable geoscientists to map the Earth's internal structure. Certain seismic observations, however, remain puzzling, such as the unexpected spatial variability in the speed of seismic waves ...
