Abstract: Most marine renewable energy (MRE) technologies are still in their infancy. Many uncertainties remain regarding MRE systems’ impacts on the marine environment and species where they are ...

Acoustic telemetry has emerged as a pivotal tool in fish research, enabling scientists to monitor the movements, behaviours and survival of aquatic species with unprecedented spatial and temporal ...

An acoustic transmitter -- or tag -- emits unique signals or 'pings' when scientists want to study the long-distance movement of marine animals. However, this method has limitations. Using a movement ...

Abstract: We present a radioactively powered acoustic transmitter for application in wireless sensor nodes. The acoustic transmitter integrates a piezoelectric acoustic transducer with a ...

The ‘dinner bell’ hypothesis posits that marine mammals hear or otherwise sense soundwaves produced by acoustic transmitters and use the signal to selectively prey on fish carrying them. A dual ...

The detection depth of current borehole acoustic reflection imaging is only tens of meters without high resolution. This considerably limits its wide application in the identification and fine ...
