ABSTRACT:
A method of processing data from a co-located hydrophone-geophone pair of seismic receivers of an ocean-bottom cable system. Ambient noise is obtained for the hydrophone and geophone. A relative noise signal is determined by finding the normalized difference between geophone and hydrophone noise signals. Geophone and hydrophone data signals are then scaled by an amount equal to the relative noise signal.
