Ocean Ecosystem Affected By Powerful Internal Waves: Study
2014-01-09 06:08:08

Gerard LeBlond for redOrbit.com - Your Universe Online New research on the ocean’s hidden waves was conducted in a lab and in the South China Sea. According to a January 8 report from MIT news, internal waves can be hundreds of feet tall and produce damaging effects to the climate and the ocean’s ecosystem. Experiments in laboratories and in the ocean have scientists claiming to have solved the mystery of what causes the largest internal waves in the world. The new findings,...

Lee Rannals for redOrbit.com — Your Universe Online Invisibility cloaking may one day help to shield ships floating around in the ocean from waves, according to research presented at the Annual Meeting of the American Physical Society (APS). The new approach to invisibility cloaking is based on the influence of the ocean floor's topography on various "layers" of ocean water. Reza Alam, assistant professor of mechanical engineering at the University of California,...

MESSENGER scientists have concluded that waves driven by the Kelvin-Helmholtz (KH) instability play a key role in driving Mercury's magnetosphere. In a paper published recently in the Journal of Geophysical Research, the team reports on frequent detections of such waves at the outer edge of the innermost planet's magnetosphere. The paper was selected as an Editor's Highlight by the journal editor, and its findings are scheduled to be featured as a Research Highlight in Eos, the weekly...

Radio broadcasters compete for airwave space in the saturated FM range, in detriment to AM wavebands with a poorer sound quality. Nevertheless, frequencies at wavebands less than 30 MHz (AM ones) could well have a new opportunity, with terrestrial digital radio broadcasting. The Digital Radio Mondiale (DRM) international consortium is working on the development of a universal system that will provide clarity which is close to that of FM, besides other advantages such as the multilingual...

By studying seismographs from the earthquake that hit Chile last February, earth scientists at the Georgia Institute of Technology have found a statistically significant increase of microearthquakes in central California in the first few hours after the main shock. The observation provides an additional support that seismic waves from distant earthquakes could also trigger seismic events on the other side of the earth. The results may be found online in the journal Geophysical Research...

Geologists from the University of Rhode Island and Princeton University, in collaboration with Lawrence Livermore National Laboratory, have taken an important step toward helping the United States government monitor nuclear explosions by improving a 3-dimensional model originally developed at Harvard University. The improvements make the model more accurate at detecting the location, source and depth of seismic activity. The results of their research were presented today at a meeting of the...

Waves impact offshore structures, submarine navigation, more Scientists at the University of Rhode Island are gaining new insight into the mechanisms that generate huge, steep underwater waves that occur between layers of warm and cold water in coastal regions of the world's oceans. David Farmer, a physical oceanographer and dean of the URI Graduate School of Oceanography, together with student Qiang Li, said that large amplitude, nonlinear internal waves can reach heights of 150 meters or...

U.S. scientists believe they have made great headway in understanding what have been termed, freak waves. These rogue waves are relatively large and spontaneous ocean surface waves that are a major threat to large ships and ocean liners. They have a height of more than twice the significant wave height (SWH). They are not necessarily the biggest waves at sea, but they are incredibly large compared to the state of the sea.  U.S. oceanographers developed a computer simulation that might...

Research at the University of Liverpool has shown it is possible to develop an "Ëœinvisibility cloak' to protect buildings from earthquakes. The seismic waves produced by earthquakes include body waves which travel through the earth and surface waves which travel across it. The new technology controls the path of surface waves which are the most damaging and responsible for much of the destruction which follows earthquakes. The technology involves the use of concentric rings of...

  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
