The primary objective of this effort is to develop combined automated whistle and echolocation click classifiers for odontocete species in the northwest Atlantic Ocean, the waters surrounding the Hawaiian Islands and the temperate Pacific Ocean. We will also incorporate ancillary information e.g., vocalization rate, relative abundance of whistles and clicks, latitude of acoustic encounter about acoustic encounters into the classifiers in an effort to improve the accuracy of classification results. These classifiers will be implemented in an existing whistle classifier, known as the Real-time Odontocete Call Classification Algorithm ROCCA. ROCCA currently is available to users as a module in the acoustic processing software platform PAMGuard Gillespie et al. 2008. Additionally, we will examine geographic variation in the characteristics of whistles and clicks produced by species that are found in two or more of the three areas included in this effort. These comparisons will provide important information about the necessity of creating different classifiers for different geographic areas.
