Challenges to Characterization of Sound Produced by Marine Energy Converters
The acoustic characteristics of marine energy converters are of interest to those attempting to quantify their environmental effects at larger scale. Such efforts are complicated by the time variation in marine energy converter sound caused by changes in the environmental forcing and converter operation, the difficulty of identifying marine energy converter sound amidst background noise from a range of sources, and the potential masking of marine energy converter sound by non-propagating flow-noise. This chapter discusses each of these challenges and proposes potential solutions to overcome them in a cost-effective manner.

Many thanks to Chris Bassett for reviewing an early draft of the chapter and providing helpful comments, as well as subsequent comments from three anonymous reviewers. Thanks also to Paul Murphy for the example of flow-noise from a bottom-mounted hydrophone at the US Navy wave energy Test Site.
