Active detection of marine mammals during seismic surveying

摘要

An embodiment according to one or more aspects of the present disclosure for conducting a marine survey includes towing a survey spread comprising a plurality of receivers and an energy source along a selected course; emitting a signal from an energy source; receiving backscattered acoustic signals at the receivers; and actively detecting a cetacean from the received data.

主权项

1. A method for actively detecting marine mammals during a seismic survey, comprising:
towing a seismic spread having one or more sources and one or more receivers; emitting acoustic signals from the one or more sources, such acoustic signals generating backscattered energy when the acoustic signals intercept a marine mammal and a geological formation; receiving at least some of the backscattered energy at the one or more receivers; generating data from the at least some of the backscattered energy; and processing the data to initially detect the marine mammal based on time origin of the acoustic signals and the time at which at least some of the backscattered energy is received at the one or more receivers.
