Attenuating the ice flexural wave on arctic seismic data David C. Henley (CREWES) SUMMARY____________________________________________________________ Although providing good surface coupling for seismic surveying in the arctic floating ice also generates of one of the most powerful known coherent noises—the ice flexural wave. This set of modes is unique in its massive dispersion with the highest frequency energy propagating at near the ice compressional velocity and the lowest frequencies often moving at speeds well below air velocity. While its large dispersion makes the ice flexural wave difficult to attenuate using conventional techniques such as f-k filtering it suggests the use of the
