Navy uncover Clyde's deep secrets

The scan showed HMS Dasher lying on the sea bed

The Royal Navy's most advanced seabed survey ship has revealed the secrets of the depths of the Firth of Clyde.

Hydrographic survey vessel HMS Echo has been visiting the waters around Glasgow for the first time.

The ship used sonar to create a three-dimensional image of the wreck of the World War II aircraft carrier HMS Dasher, located south of the Cumbraes.

Using advanced navigation and communication systems, HMS Echo has scanned the river bed up to Govan.

Echo's multibeam sonar means she can create detailed images of the sea bed, enabling modern charts to be produced with the very latest up-to-date information for mariners.

The 3,500-tonne ship is berthing at the King George V Dock on the River Clyde for crew rotation and some recreation before continuing a busy survey programme off the west coast of Scotland.

Lieutenant Commander Bruce Badrock, the ship's executive officer, said: "Although it will be a very busy time with a third of the crew changing over, we're hoping to make the most of our time here in a city with a reputation as one of the best runs ashore in the UK."
