Remote-controlled aircraft are expected to revolutionise academic marine research in Scotland by the summer.

The planes, which will be piloted from the ground, are to be used by a research facility in the Highlands to collect scientific data.

They can monitor a range of subjects from the movement of jellyfish to the arrival of non-native species of seaweed, the melting of sea ice and how mammals such as seals relate to offshore energy projects.

A crew to fly the unmanned aerial vehicles (UAVs) is now being trained at Scottish Association for Marine Science (SAMS) laboratories at Dunstaffnage, north of Oban.

Philip Anderson, SAMS' Head of Marine Technology and a veteran of the British Antarctic Survey (BAS), is leading the team.

He said they would be trained at SAMS and that initial flights would be from the North Argyll base, but added: "In the longer term the plan is to launch the aircraft from research vessels, thereby increasing enormously the area they can cover."

He said the coast of Argyll was an ideal area to develop these aircraft, with hundreds of miles of desolate coastline to survey as they fly below 400ft.

"This aircraft can scoot off over a mile away in all directions, allowing for a huge survey footprint compared to what a vessel by itself could achieve. By next year we hope to be able to head north to the Arctic to look at the sea ice," Mr Anderson said.

Apart from take-off and landing, when the UAVs are controlled by radio, the aircraft fly according to pre-programmed flight plans. But before that there is a lot of paperwork to be completed. "When we are doing the tests at the base here at Dunbeg, we will also have to make sure we are not interfering with the flights to and from the airport at North Connel," said Mr Anderson

The UAVs are being developed at a cost of between £1000 and £10,000.
