The March JASA Express Letters cover features a photo of two dolphins, taken by Cristina Marcolin, one of the coauthors of the article, “Dolphin and porpoise detections by the F-POD are not independent: Implications for sympatric species monitoring.” (The full author list of the article is Mel Cosentino, Cristina Marcolin, Emily T. Griffiths, Estel Sánchez-Camí, and Jakob Tougaard.) The article discusses issues with the offline classifiers of F-POD, which is designed for passive acoustic monitoring of odontocetes.
