A method that allows real time detection, localization, trajectory, counting and identification of each member of a marine mammal group has been developed.
The requirement is a simple laptop and fixed or mobile hydrophone array.

Points forts

Nowadays, several methods exist to analyze the trajectory of the whales but they
have major disadvantages:

  • The prejudice to the marine mammal (methods using active sonar)
  • The approximate whale watching methods
  • Non-reliable results (methods requiring the sound speed profile in the water). Wrong results provided if the profile is not up-to-date
  • Real time detection not possible, e.g. Marine
    Mammal Monitoring (methods requiring a cluster of
    PC to analyze the data).
