Antarctic ice shelf collapse possibly triggered by ocean waves, Scripps-led study finds
Depicting a cause-and-effect scenario that spans thousands of miles, a scientist at Scripps Institution of Oceanography at the University of California - San Diego and his collaborators discovered that ocean ...
World's biggest Wave Hub installed off UK coast
Triple whammy triggered Samoa tsunami (Update 2)
A tsunami that hit the Pacific islands of Samoa and Tonga last year was generated by three earthquakes unleashed by a seismic mechanism that has never been observed before, scientists said on Wednesday.
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, ...
New understanding of Earth's lithosphere-asthenosphere boundary beneath the Pacific Ocean
Scientists have long speculated about why there is a large change in the strength of rocks that lie at the boundary between two layers immediately under Earth's crust: the lithosphere and underlying asthenosphere. ...
Mega-canyon discovered beneath Greenland ice sheet
A previously unknown canyon hidden beneath two kilometers of ice covering Greenland has been discovered by a group of scientists, led by a team from the University of Bristol.
Tsunami sensor detects mysterious background signal in Panama
An unusual signal detected by the seismic monitoring station at the Smithsonian Tropical Research Institute's research facility on Barro Colorado Island results from waves in Lake Gatun, the reservoir that ...
Maximum height of extreme waves up dramatically in Pacific Northwest
A major increase in maximum ocean wave heights off the Pacific Northwest in recent decades has forced scientists to re-evaluate how high a "100-year event" might be, and the new findings raise special concerns ...
Is there an ocean beneath our feet?
(Phys.org) —Scientists at the University of Liverpool have shown that deep sea fault zones could transport much larger amounts of water from the Earth's oceans to the upper mantle than previously thought.
Chips that can steer light
If you want to create a moving light source, you have a few possibilities. One is to mount a light emitter in some kind of mechanical housing—the approach used in, say, theatrical spotlights, which stagehands ...
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 ...
Magma in mantle has deep impact: Study suggests rocks melt at a greater depth than once thought
Magma forms far deeper than geologists previously thought, according to new research at Rice University.
Deciphering the mysterious math of the solar wind
(Phys.org)—Many areas of scientific research—Earth's weather, ocean currents, the outpouring of magnetic energy from the sun—require mapping out the large scale features of a complex system and its ...
Tidal energy farms influence the natural transport of sands
(PhysOrg.com) -- Tidal stream farms, in which electricity is generated by turbines from regions of strong tidal flow, may influence the natural balance of marine sands, according to research at Bangor University.
