Abstract: An embodiment according to one or more aspects of the present disclosure for conducting a marine survey includes a survey spread comprising a plurality of receivers and an energy source that is towed along a selected course while a signal is emitted from an energy source. A plurality of receivers receive data comprising a detection sampling frequency and a survey sampling frequency. The survey sampling frequency is monitored to detect a cetacean vocalization and to position the cetacean at least while conducting the seismic survey. Pursuant to the location of the cetacean actions can be taken to protect the cetacean and to minimize disruptions in conducting the seismic survey.
