15: Effect of Broadband Nature of Marine Mammal Echolocation Clicks on Click-based Population Density Estimates

This project aims to demonstrate how the detection process of broadband clicks can be modeled for different marine mammal species and detectors and assess the magnitude of error on the estimated density due to various commonly used simplifying assumptions in the modeling process. Our main purposes are to quantify potential biases in the population density estimate for selected species and detectors caused by narrowband assumptions made in the passive sonar equation when modeling detectability of broadband clicks, and to understand the factors affecting the magnitude of this bias to enable extrapolation to other species and detectors.
