Patent ID: 7864628

Claim:
A method for attenuating flexural wave information from seismic information, the method comprising: receiving the seismic information using an information processing device interface, the seismic information having a plurality of directional components acquired using a multi-axis motion sensor coupled to ice floating on a body of water, the seismic information including desired seismic information and the flexural wave information; using a band filter to limit seismic information in each of the plurality of directional components to a hand containing noise; generating a noise model of the flexural wave information using at least one of the plurality of seismic information directional components using an information processing device; rotating a phase of at least one of the plurality of directional components; improving the noise model using an adaptive correction filter; and applying the improved noise model to at least one directional component of the received seismic information to attenuate the flexural wave information wave in the seismic information, wherein the at least one of the plurality of directional components includes a horizontal component, and wherein the act of rotating a phase of the at least one of the plurality of directional components further comprises rotating a phase of the horizontal component by 90 degrees.
