The long-term goal is to identify if sound is produced or modulated by cetacean prey species in the water column using passive and active acoustic methods. Given the universal presence of backscatter organisms in all oceans and the likely relevance of these sound patterns to species involved and their predators, this is directly relevant to naval operations. It can a be used in long-term monitoring leading to improved cetacean predictability and mitigation during naval exercises and b shed light on the relationship of acoustic backscatter and ambient sound across time and space, which is relevant to the U.S. Navy sonar community.
