Abstract

A software package is presented which models the effects of underwater noise on marine mammals. It consists of three main parts: an acoustic source model, a sound propagation model and a bioacoustic impact model. It has been corroborated in the field by measurements of the noise field, and visual and passive acoustic surveys of marine mammals. The software package was written for Environmental Impact Assessments (EIA), and has been used to aid research, to apply for permits of marine operations, to monitor marine mammals, to design mitigation protocols, and to guide environmental management and decision-making. This article gives an overview of our software and presents results of various EIAs.
