Aerial surveys are being carried out over Skye to help archaeologists investigate a 12th Century Viking shipbuilding site. Boat timbers, a stone-built quay and a canal have already been uncovered at Loch na h-Airde on Skye's Rubh an Dunain peninsula.

The Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS) has launched the air surveys. Staff hope to pinpoint new sites for investigation. Working with marine archaeologists, RCAHMS also hope to find potential dive sites for searches for the remains of ships and other artefacts.
