A Population Consequence of Acoustic Disturbance Model for Cuvier s beaked whale (Ziphius cavirostris) in Southern California: Photo-ID and Tag Data Components
Abstract
This proposal represents one element of a larger collaborative proposal to support the extension of the Blainville s beaked whale (Mesoplodon densirostris) Population Consequences of Acoustic Disturbance (PCAD) model to Cuvier s beaked whales (Ziphius cavirostris) in the Southern California Bight. While this effort includes no fieldwork, it will consolidate and build on existing data sets, and provide a framework that will inform future data collection. This proposal represents the visual survey-derived data components that are required for this process, including sighting and group composition rates, population structure and individual life history parameters derived from photo-identification, and diving and movement behavior from satellite tags. This program focuses directly on Cuvier s beaked whale. It combines visual, tag, biophysical, direct ship tracks and passive acoustic dat for this purpose. This multidisciplinary approach is reflected in the composition of the program team, which combines expertise in statistical modelling, passive acoustic signal processing, behavioral biology, and animal tagging. Using these data sets and expertise, we will extend the PCAD model for evaluating the population level effect of sonar on Cuvier s beaked whale, a priority species, at SCORE and AUTEC.
