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
