Technology offer : Identify and track multiple emitting whales in real time by using passive acoustics
Detecting and tracking cetaceans helps to limit impact of human activities and to assess benefits of protected areas.
However, detection methods using active sonar disrupt cetaceans and their environment. Plus, no passive method to detect in real time on a simple computer several click emitting sources currently exists. Watching whales during their emersion remains an approximate method for counting whales.
Our process includes fixed or mobile hydrophones and data treatment using algorithms. It ensures real time detection, localization, determination of the trajectory and identification of each member of a marine mammals group. Analysis of noises from whales provides information about the group, age and gender of subjects, language and behavioral interactions.
