CV16030 Rockall OBS network retrieval survey

Geophysics Rockall survey in the North Atlantic Ocean. - to monitor part of the Irish shelf area from local earthquakes (it is Ireland's most seismically active region but has never been locally monitored so we do not have a well constrained understanding of seismic activity offshore) - to determine the effects of the shelf break on microseism propagation from the deep ocean to the shelf areas and onto land. (Through very recent methodological developments Microseisms - ocean wave generated seismic wave in the solid earth - can now be used for seismic imagery but there are still a lot of details to better understand before the methodology is standard. We are ideally positioned to undertake this work in Ireland as the NE Atlantic is a microseism hotspot generation area) - to generate pilot sub-surface seismic images using microseisms along the deployed OBS profile, as a pilot demonstration of the strong potential of this work in environmentally neutral offshore imagery. - to further constrain development of microseisms as an ocean wave height proxy.
