Dear colleagues, We are excited to share a new open acoustic dataset of manatee vocalizations designed to support machine learning detector development efforts. This dataset includes 0.5-second WAV clips from African and Florida manatees recorded at four sites (18,129 manatee vocalizations clips and 23,444 noise clips). Access the dataset here. <https://doi.org/10.6073/pasta/f6b14cae6916da998808a8395cf38ae0> Citation: Rycyk, A., V. Cargille, D. Bolaji, C. Factheu, U. Ejimadu, C. Berchem, and A. Takoukam Kamla. 2025.
