    Abstract: In understanding the ocean soundscape, most modeling efforts have been focused on shipping, wind and then other anthropogenic sound sources. In many environments, at particular frequencies, the soundscape can be dominated by vocalizations made by marine animals (mammals and fishes). From the navy perspective these are considered biological noise. Ih this paper we present a methodology for predicting the marine mammal contribution to the soundscape by combining marine bioacoustics, dynamical oceanographic modeling, ecology and ocean acoustic propagation modeling. In addition to predicting the contribution of animal sounds to the soundscape, the technique permits the generation of large sets of animal vocalization training data for ML/AI classification algorithms.
