This British Geological Survey (BGS) marine geophysical and multibeam and survey took place in June/July 2012 in the area of Loch Broom and Gruinard Bay on board the RV White Ribbon. 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.
