Effects of sound on the marine environment (ESME): an underwater noise risk model

Effects of Sound on the Marine Environment (ESME) is a computer model of the effects of underwater sound on marine life. The modular design behind the ESME model is motivated by the sonar equation, with subcomponent models for characterization of the source, for modeling of sound transmission through a medium, and for receiver properties (e.g., hearing abilities, behavioral responses to sound, and receiver distribution and abundance). Each subcomponent of ESME is intended to capture the current state of understanding in the relevant scientific field and to be capable of being updated as the understanding in the field advances. ESME is envisioned to have three primary applications: 1) retrospective studies of historical data, 2) predictive modeling of anticipated outcomes from a given scenario of sound in a marine environment, and 3) prescriptive guidance for research investments and efforts that will likely have the greatest effect on increasing confidence in decisions about underwater sound use and its effects
