Dear MARMAM Colleagues My co-authors and I are pleased to announce the publication of our new paper published as a note in Marine Mammal Science. Shabangu FW, Andrew RK, Findlay K. 2020. Acoustic occurrence, diel-vocalizing pattern, and detection ranges of southern right whale gunshot sounds off South Africa's west coast. Mar Mam Sci. 1–18. https://doi.org/10.1111/mms.12760 Lay abstract We used passive acoustic monitoring to study southern right whales, a species of recent high concern in South African waters. Gunshot sounds of southern right whales were heard sporadically throughout the year, with the majority of sounds heard in spring. Whales vocalized more at dusk and night to maintain acoustic communication with conspecific when visibility was limited underwater. Model predictions suggest that vocalizing whales could be as far as 80 km from the acoustic recorder. Low detections of gunshot sounds of southern right whales corresponded with the recent decline in whale counts from annual aerial survey in this region.
