Rockall Bathymetry 2011 and 2012

In 2011 and 2012 MRV Scotia surveys 0711S and 0712S used a Reson PDS2000 multibeam echosounder to map the seabed around Rockall. Data were collected at 200 and 400 KHz frequencies at a spatial resolution of between 2 and 4 metres depending on depth. An area of approximately 6 nautical miles (north-south) by 9 nm (east-west) was mapped over the 2 surveys. The data were then merged, cleaned and processed using CARIS software HIPS and SIPS

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.
