- Title
On Marine Mammals Signals Analysis by Retrieving Inter-Click Interval Information.

- Abstract
The occurrence of typical inter-click intervals (ICIs) is considered for the analysis of marine mammals signals. A new framework for passive acoustic monitoring is introduced based on ICI information retrieved from ocean acoustic data. The proposed scheme involves extraction of plausible click trains consist of echolocation clicks from various annotated data of marine mammals; here we investigate sperm whale (Physeter macrocephalus), Pacific white-sided dolphin (Lagenorhynchus obliquidens), and killer whale (Orcinus orca). Then a preliminary investigation on the analysis of the proposed ICI-based parameters is carried out. In order to characterize the biological clicks, some distinct information of ICI are derived from the click trains, which are extracted from the phase slope functions of the signals. The experimental results obtained from real-recorded ocean data reveal that the proposed ICI-based scheme can be a useful tool for monitoring various types of marine mammal vocalizations.
