High resolution bathymetry data of Rockall and Helen's Reef collected 2011-2012 as part of the ROAME Offshore Fisheries and Conservation (OFFCON) project. Rockall, a tiny island just 19 metres high, sits on the very extremity of Scotland’s marine environment. Some 180 miles due west of St. Kilda, it is buffeted year round by the extreme winds and swell that the North Atlantic weather generates. As such, it is Scotland’s only truly offshore shallow water ecosystem. The islet of Rockall is actually the only part of vast plateau of submerged continent that remains above sea-level.
