Analysis of Sperm Whale Acoustic Signals in the Gulf of Mexico and the Mediterranean

Abstract

To design, develop, and simulate an automated procedure for passively tracking sperm whales in three- dimensions, using natural vocalizations recorded on two towed arrays, deployed either alone or in conjunction with dive tags. The algorithms would permit automated tracking of multiple animals over complete dive cycles, producing statistically significant sample sizes for evaluation of controlled-exposure studies. When used in conjunction with a dive tag, the algorithm would permit better resolution tracking of animals detected on both the tag in array, effectively increasing the number of animals tracked by the tag.
