The North Atlantic Right Whale (NARW) population is currently teetering on the brink of extinction, with a mere approximate count of 350 individuals remaining. These animals have been protected under the Endangered Species Act since 1970. Today, the survival of right whales is imperiled primarily due to vessel collisions, net entanglements, and habitat degradation. This paper presents a novel system of animal-computer interaction founded on the identification of bioacoustic signatures. Initially, NARWs' vocalizations were transformed into spectrograms, which were subsequently inputted into a Convolutional Neural Network (CNN). To enhance robustness against environmental noise, techniques such as time warping, frequency masking, and time masking were employed. The outcomes of our study indicate that the proposed system holds potential for establishing a closed-loop interaction framework between vessels and NARWs. This framework could enable vessels to adapt their speed or avoid routes frequented by NARWs. Furthermore, this article discusses the potential benefits of employing networked sensors, such as Internet of Things (IoT) devices, to augment NARW monitoring and data collection efforts.

Humpback whale (Megaptera novaeangliae) nonsong vocalizations, or social calls, are much more poorly understood than humpback song. We examined humpback whale social calls from a foraging ground in southern British Columbia (BC) and developed a catalog for humpback social calls in BC. We tagged four humpback whales on the eastern edge of Swiftsure Bank, BC, in early September 2020, with a passive acoustic and movement tag. We manually classified 32 call types in our data set based on comparisons with published classifications of humpback social calls. Many of the calls identified in our data set had similar characteristics to calls from other locations. We also used two statistical classification methods, a cluster analysis and a random forest. The cluster analysis grouped 20 of these call types into four categories, and the random forest classifier was able to accurately classify all 20 call types 87.6% of the time. This study fills a geographical gap of humpback whale social calls on foraging grounds and is a first step towards categorizing the social calls of humpback whales in BC.
