Divers are exploring the remains of German warships scrapped in Scotland after the First World War.

More than 70 vessels from the German High Seas Fleet were scuttled or beached in the Scapa Flow, Orkney, at the end of the conflict.

A number of ships were raised and salvaged from the 1920s onwards, leaving debris scattered across the seabed.

Divers from the Orkney Research Centre for Archaeology began exploring the remains on Friday with the aim of identifying which vessels the remains came from.

They also hope to uncover the fate of lost ships.

A spokesman said: "Under a clearing blue sky, the team sailed out into Scapa Flow on Friday on board the MV Halton to complete the second phase of the German High Seas Fleet Scrap Sites project.

"Concentrating on sites located through side scan sonar survey completed in phase one, the archaeologists recorded and documented extensive remains of the First World War fleet that still lie on the seabed.

"The conditions underwater were perfect and visibility was good, allowing the divers to take some excellent photographs and video footage while recording and surveying the wreckage left behind following the inter-war salvage efforts on the scuttled German High Seas Fleet."
