Flexural Wave Attenuation

An apparatus for attenuating flexural wave information from seismic information, the apparatus comprising:

• an information processing device;
• and
• an information processing device interface that receives the seismic information for processing in the information processing device, 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 further including the flexural wave information,
• wherein the information processing device generates a noise model of the flexural wave information using at least one of the plurality of seismic information directional components and uses an adaptive correction filter to improve the noise model, the information processing device 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.

A computer-readable medium having computer executable instructions stored thereon, that when executed using a computer, perform 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;
• 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;
• 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.
