Naval sonar systems work like acoustic floodlights, sending sound waves through ocean waters for tens or even hundreds of miles to disclose large objects in their path. But this activity entails ...

Scientists have found a clever new way of measuring ocean warming, using sound waves from undersea earthquakes. The researchers say the "hack" works because sound travels faster in warmer water.

and his colleagues point out that sound waves can travel thousands of miles through the ocean. "Sound is a fundamental cue for feeding, navigation, communication and social interaction in the ...

to send sound waves down into the ocean and out in all directions. These waves can travel over large distances as they bounce off any obstacles or fish in their path. The same or a second boat ...

These ripples are waves travelling through the water. Like ocean waves, these ripples are transverse waves because the surface of the water moves up and down, at 90° to the direction that the ...
