Acoustic Detection, Behavior, and Habitat Use of Deep-Diving Odontocetes

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. The primary objectives of the work a...

Description
Summary: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. The primary objectives of the work are: 1. Develop and evaluate passive acoustic detection/classification 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. A National Oceanographic Partnership Program Award. Prepared in cooperation with University of La Laguna, Tenerife, Spain and University of Aarhus, Aarhus, Denmark. The original document contains color images.
