Scientists from DIAS Geophysics deployed 10 Broad Band Ocean Bottom Seismographs (OBSs) units across the shelf offshore Donegal and out into the Rockall Trough in order to study microseims. Compared to earthquakes, microseisms represent background seismic noise generated by ocean wave pressure fluctuations on the sea floor which generate low frequency seismic waves. This project is a collaboration between the Dublin Institute for Advanced Studies (DIAS) and the Helmholtz Center GFZ Potsdam (Germany) with instruments provided by the Alfred Wegener Institute (AWI in Germany). Scientists on board the Celtic Voyager comprise 4 DIAS scientists and 2 German technicians from AWI.
