Method and system for passive acoustic monitoring in seismic survey operations

摘要

A system for passive acoustic monitoring in connection with seismic surveying includes a survey vessel (10) having a recording system thereon. At least one seismic energy source (24) is coupled to the vessel (10) by a first towing cable (35). The towing cable (35) includes at least one conductor therein. At least one seismic sensor streamer (20) is coupled to the vessel by a lead in cable. At least one acoustic sensor (28) is coupled to the at least one source by a second towing cable (26). The second towing cable (26) includes at least one signal conductor configured to transmit signals from the acoustic sensor to the at least one conductor in the first towing cable. The at least one acoustic sensor (28) is configured to detect marine mammal vocalization.
