*WINNER* Caribbean Delphinidae Click Classifications

Abstract

This research focuses on identifying animals of the Delphinidae family found in the Caribbean by analyzing acoustic signals. Delphinids produce large numbers of acoustic signals identified as echolocation clicks which provides a useful classification system. Recent studies have established that the fundamental frequency of the majority of whistles used for social communications covers the frequency range of 2–35 kHz and up to 100 kHz for the harmonic frequencies. The challenge in click classification results from recognizing patterns among many sources of variability. Our findings will be presented by figures of network relationships between clicks and a detailed exploratory analysis to highlight clusters and subsets of training and test data along with clustering algorithms.
