Seismic lines from the previous survey (2011-04) were re-run using a Surface Tow Boomer for a direct comparison to see if the underlying sediments had been disturbed by the drill; further lines were added for greater data density. Lines were run east to west, parallel with the contours, with 100% overlap to ensure safety in the shallow water. 20 lines were completed in total; an area of 1km2 was completed with lines approx 500m in length. A multibeam survey was run successfully using a Kongsberg EM3002D multibeam system; the aim was to find concrete blocks on the seabed that were anchoring a cable related to the drill operation. See the Cruise Report for more information.

| abstract |
This British Geological Survey (BGS) marine geophysical and multibeam survey took place in April 2012 in the area of Ardmucknish Bay on board the RV White Ribbon. This was a follow up survey to the previous work carried out in this area in 2011 (2011/4). QICS (Quantifying and monitoring potential ecosystem impacts of geological carbon storage) was a scientific research project funded by NERC; its purpose was to improve the understanding of the sensitivities of the UK marine environment to a potential leak from a carbon capture storage (CCS) system. The aim of the survey was to assess any affect the drilling of the borehole had on the underlying sediments. Sea floor bathymetry data were collected using a Kongsberg EM3002D multibeam system. Sub bottom seismic profiling data were collected using an Applied Acoustics surface tow boomer (STB). These data are archived by BGS. Technical details of the survey are contained in the BGS Report of Survey. Webpage www.bgs.ac.uk/QICS/.
