Greetings - A workshop on the status and future of underwater hearing research was convened from September 10-12 , 2013 in San Diego, California. The workshop was held to evaluate recent and current research, and identify future research avenues with the greatest potential for advancing the state of knowledge on underwater hearing in marine mammals. The workshop consisted of three days of presentations by members of the scientific community actively involved in the study of marine mammal hearing; in particular, research into the relationship between sound exposure and temporary threshold shift, masking, anatomically-based modeling of marine mammal auditory systems, and behavioral and evoked potential audiometry. The presentations were independently reviewed by experts that are active in both marine mammal and terrestrial mammal/human hearing research communities. The workshop was jointly funded by the Living Marine Resources, National Marine Fisheries Service, and the Office of Naval Research. A report of this workshop is now available for download at the National Marine Mammal Foundation website, under Technical Reports ( http://nmmf.org/resources/publications/).
