Description / Abstract:

This Technical Report presents the outcome of a Working Group that was established to determine broadly applicable sound exposure guidelines for fi shes and sea turtles. After consideration of the diversity of fi sh and sea turtles, guidelines were developed for broad groups of animals, defi ned by the way they detect sound. Different sound sources were considered in terms of their acoustic characteristics and appropriate metrics defi ned for measurement of the received levels. The resultant sound exposure guidelines are presented in a set of tables. In some cases numerical guidelines are provided, expressed in appropriate metrics. When there were insuffi cient data to support numerical values, the relative likelihood of effects occurring was evaluated, although the actual likelihood of effects depends on the received level. These sound exposure guidelines, which are based on the best scientifi c information at the time of writing, should be treated as interim. The expectation is that with more research, the guidelines can be refi ned and more cells in the tables completed. Recommendations are put forward defi ning the research requirements of highest priority for extending these interim exposure guidelines.
