The research paper discusses the use of echolocation clicks emitted by sperm whales for navigation purposes underwater. These clicks serve as a unique pattern, and this study uses the stability of these patterns as a detection metric for identifying the presence of these clicks in noisy environments. The approach presented can effectively distinguish between noise transients and handle emissions from multiple sperm whales. The research was tested using three datasets from the Mediterranean Sea, Dominica Island, and the Bahamas. The method showed a better trade-off between precision and recall compared to other detectors and significantly reduced false detection rates in noisy environments.
