Underwater noise pollution threat to marine life

A breakthrough study by a specialist European research team, including scientists at the University of St Andrews, shows man-made underwater noise pollution is picked up by whales in a similar way they sense natural predators, ...

Multibeam sonar can map undersea gas seeps

A technology commonly used to map the bottom of the deep ocean can also detect gas seeps in the water column with remarkably high fidelity, according to scientists from the University of New Hampshire and the National Oceanic ...

Using AI to map marine environments

Sonar is commonly used to map the ocean floor, and seabed composition (e.g. mud, clay or rock) affects the way the sound is reflected back. Salinity, depth and water temperature also affect how sound waves are propagated ...

Human hair used to make flexible displays for smart devices

Researchers from the Queensland University of Technology and Griffith University have developed a method for turning small hair strands into carbon nanodots, which are tiny, uniform dots that are one-millionth of a millimeter. ...
