There is currently an urgent need to autonomously record, detect, classify, and report marine mammal calls for both research and mitigation applications. For marine mammal research, such a capability would greatly improve the efficiency of finding animals at sea for study e.g., for tagging or photo-identification. For the National Oceanic and Atmospheric Administration NOAA, such a capability would allow improved monitoring of the distribution and occurrence of vocalizing animals for improving our understanding of stock structure and characterizing anthropogenic threats. For both the Navy and some industries that are interested in mitigating their interactions with marine mammals, real-time detection can augment and improve the efficiency of traditional detection methods e.g., aerial and shipboard surveys, while providing persistent surveillance for marine mammals when traditional methods are ineffective e.g., at night, during rain, fog, snow, or high winds.
