Suffolk Atlantis to reveal its murky secrets

Dunwich, on the Suffolk coast, was a thriving metropolis before a series of storms and sea surges consigned the city to the North Sea five centuries ago.

Stuart Bacon, a marine archaeologist, has spent the last 30 years trying to discover the secrets of the city through a series of dives, but due to extremely poor visibility he has never seen the ruins.

Scientists will use the latest acoustic imaging technology to penetrate thick layers of silt and create the first images of the lost city, which lies between 10 and 50ft down.
