The goal of this project is to develop acoustic moorings that will allow concurrent passive and active acoustic data collection to be used in the SCB, an area of high naval use, for refinement of predictive models of cetaceans and their prey. The moorings will consist of a passive acoustic component for monitoring of cetaceans, active acoustic echosounders at two depths to monitor both baleen whale and beaked whale prey, CTDs at the same depths as the active echosounders, and a redundant acoustic release system. Temperature, salinity, and pressure measurements will be collected. This upgrade to a multi-faceted system will mean that research is no longer limited to cetacean taxa, but will allow studies of cetaceans and prey in an integrated way. Beyond their utility for cetacean-prey studies and marine mammal monitoring, these systems will also be integral for continued education of young marine mammal scientists and oceanographers by allowing a truly multidisciplinary perspective, by merging acoustics, biology, and oceanography to answering a suite of ecological questions.
