Abstract:

LONG-TERM GOALS Passive acoustic monitoring is a key enabling technology in mitigating the effects of Naval activities on sound-sensitive cetaceans. The goals of this project are to obtain and disseminate critical information needed for the design of acoustic monitoring systems while seeking also to define behavioral modes that may help explain the acoustic sensitivity of some species. OBJECTIVES 1. Develop and evaluate passive acoustic detectionclassification methods for click and whistle sounds produced by deep-diving toothed whales. 2. Examine the relationships between diving, acoustic behavior, habitat use and group size with implications for acoustic detection and density estimation of toothed whales. 3. Correlate fine-scale oceanographic parameters with foraging behavior of tagged whales to predict habitat suitability and movement patterns.
