A METHOD FOR IDENTIFYING A POSITION OF A SOURCE OF NOISE IN A MARINE SEISMIC RECORD INCLUDES DEFINING, FOR AT LEAST ONE SHOT RECORD, A SET OF POSSIBLE NOISE SOURCE POSITIONS (NN). A DIFFERENCE (32) BETWEEN TRAVEL TIME ( ?T) OF NOISE FROM EACH POSSIBLE NOISE SOURCE POSITION (NN) TO EACH OF A PLURALITY RECEIVER POSITIONS (16) FOR THE AT LEAST ONE SHOT ALIGNED (34) WITH RESPECT TO THE DIFFERENCE BETWEEN TRAVEL TIMES FOR EACH POSSIBLE NOISE SOURCE POSITION. THE TIME-ALIGNED SIGNALS ARE THEN STACKED (36). THE NOISE SOURCE POSITION IS DETERMINED (44) FROM THE STACKED, TIME-ALIGNED SIGNALS. |
