Abstract: A method and marine seismic processing system including an interface for receiving recorded data, wherein the recorded data includes seismic data and bio-acoustic data; a seismic data processor for estimating a source signature from the recorded data, wherein the source signature is associated with a seismic source that emits seismic waves in water during a seismic survey; and a bio-acoustic processor that estimates a presence of a mammal generating the bio-acoustic data, based on a processed signal obtained by removing the source signature from the recorded data.

Abstract: A method and apparatus are provided for managing the acoustic performances of a network of acoustic nodes arranged along towed acoustic linear antennas. The network of acoustic nodes is adapted to determine inter-node distances allowing to locate the acoustic linear antennas. The method includes: obtaining a determined layout of the network of acoustic nodes; obtaining at least one marine environment property relating to an area of performance of a survey with the network of acoustic nodes; and quantifying the acoustic performances of the network of acoustic nodes, using a sound propagation model, the at least one marine environment property and the determined layout.

Abstract: A method for localizing a marine animal in an underwater environment implemented by a passive acoustic monitoring (PAM) system. The passive acoustic monitoring system includes network of acoustic sensors adapted to carry out measurements of acoustic signals. The method includes: obtaining, from the network of acoustic sensors, measured data of an acoustic signal emitted by a marine animal; defining a space of dimensional representation of the underwater environment discretized in a plurality of predefined cells, for each cell of a predefined set, obtaining an error defined as a value of a cost function for the cell, the cost function giving a deviation between: at least some of the measured data; and corresponding theoretical data obtained by assuming the marine animal is located in the cell, the errors obtained for the predefined set of cells enabling to obtain at least one piece of information about localization of the marine animal.
