While pulsing sonar has been used by navies around the world for years, the effect of new continuous sonar on sea mammals had not been tested before.

Now, an international team of researchers led by Professor Patrick Miller at the University of St Andrews has examined the impact of this new technology on sperm whales with the first at-sea experiments. MORE
