Researchers from UCLA and international partners use a unique alignment of six spacecraft to measure the release of magnetic energy close to Earth. They discover that this energy is stored in Earth's magnetosphere and released through a process called magnetic reconnection, which powers Earth's auroras and radiation belts.
A BYU mechanical engineering professor's research reveals that internal waves play a crucial role in predicting weather, leading to frequent forecasting mistakes. By understanding how these waves move energy around, forecasters can develop better linear wave models to improve their predictions.
A Tel Aviv University researcher has developed a control algorithm that optimizes energy collection from waves by predicting wave height and force. The system doubles the energy previously collected by Wave Energy Converters (WECs), making marine energy more competitive.
Researchers at the University of Exeter have developed a system that accurately predicts wave power, enabling devices to extract twice as much energy as currently possible. This breakthrough addresses key challenges in marine energy technology, including device durability and efficiency.
Researchers have designed a new device that converts sea wave motion into electrical energy with high power density and robustness. The proposed electric linear planar switched reluctance generator addresses the challenges of low speed and irregular movements in ocean waves.
Researchers at University of Chicago and Tel Aviv University found a connection between coupled pendulums and compressed elastic films, which concentrate energy into discrete packets called solitons. Solitons are also found in other realms, such as telecommunications, where they travel through optical fibers.
Researchers estimate that harnessing 10% of Australia's near-shore wave energy could generate enough electricity to meet half of the country's present-day consumption. This could contribute significantly to Australia's goal of producing 45,000 gigawatt-hours/year of additional renewable energy by 2020.
A Scripps-led study found that extremely long waves originating along Pacific coasts may destabilize Antarctic ice shelves. The researchers propose that infragravity waves could initiate ice shelf collapse by opening crevasses and reducing ice integrity.
Oyster, developed by Queen's University Belfast and Aquamarine Power, is the world's only hydro-electric wave energy device producing power. It has the potential to meet up to 20% of the UK's energy demands and provide enough energy to power 9,000 homes.
Researchers apply aerospace principles to create a durable and efficient wave-energy system that can be placed anywhere in the ocean. The system effectively cancels incoming waves, capturing their energy while flattening them out.
Researchers found that focusing of waves by shoals and currents can increase the likelihood of freak waves by up to 10 times. Freak waves are extreme waves measuring roughly three times the size of average wave height, posing significant risks for shipping and navigation in coastal areas.
MIT researchers, led by Chiang Mei, have developed a numerical simulation model that predicts wave forces on devices and motion of the device. The research aims to optimize energy capture and provide data for efficient conversion to electrical energy. The pilot-scale device will be integrated into a new breakwater in Portugal.
Researchers found that small oyster shell reefs are effective in slowing erosion on low wave energy shorelines, but less effective in higher wave energy environments. This study suggests that oyster reefs could be a useful tool for coastal managers to stabilize shorelines under low energy conditions.
Researchers successfully amplify a phenomenon predicted by computer simulations, challenging the idea that equilibrium states are impossible in nonlinear systems. The discovery also sheds new light on the Young's modulus of materials.
Scientists have identified over 20,000 uniquely 'fetch-limited barrier islands' along coastlines worldwide. These islands differ from classic ocean-fronting barriers in their wind- and wave-shielded settings and tend to be smaller with average lengths ranging from 1 kilometer.
Experts from Oregon State University are pioneering wave power technology, which could become a major contributor to the nation's energy needs. The proposed U.S. Ocean Energy Research and Demonstration Center would evaluate existing systems and test new ones.
The HOME scientists used various instruments and equipment to track ocean energy and turbulence, finding that the Hawaiian Ridge is a site with vastly increased ocean mixing. They documented undersea internal wave energy enhanced 10 times at the ridge compared to normal open ocean areas.
Scientists have successfully measured wind's interaction with the ocean, revealing a pattern consistent with a 1957 theory. The findings could improve climate modeling and prediction of weather and wave activity.
Dr. Boufadel is developing new protocols to test the effectiveness of dispersants in oil spill cleanup. He aims to correlate shaking energy with sea state and wave height to optimize dispersant use. The EPA has shown interest in his work.
Scientists study seismic waves to understand tectonic plate dynamics, aiming to resolve the long-standing 'great plate debate'. They use data from seismometers worldwide to characterize wave origins and time delays, creating a X-ray image of the planet's internal structure.
Researchers Xiaodong Song and Don Helmberger found two distinct layers in the inner core: a spherical lower part and an uneven upper layer with different material properties. The findings may affect the formation of the Earth's magnetic field.
A computer simulation model of a tsunami wave shows how energy spreads out over hundreds of miles as it travels through deep ocean water. The model is used to estimate impact force on structures and reduce damages caused by tsunamis.
