Pockmarks are aligned to the main deep fault of the region, the SW-NE Skerryvore Fault. High resolution multibeam bathymetry and backscatter reveal the surface morphology of these seabed features to the meter scale. They appear as subcircular depressions and present several units within a generally smooth seabed. Shallow seismic and single-beam echosounder records reveal evidence of gas related activity within the subsurface strata. Electromagnetic results present a number of anomalies in conductivity associated with inhomogenities in the upper strata. These anomalies consist in a decrease in conductivity and in general, correlate well with acoustic anomalies.}, isbn = {9073781728}, url = {http://www.scopus.com/inward/record.url?eid=2-s2.0-84912149526\&partnerID=tZOtx3y1}, author = {Monteys, X. and Garcia, X. and Evans, R. and Szpak, M. and Kelleher, B. and Hardy, D.} }
