The objective of this project is to use machine learning convolutional neural networks (CNN) to classify marine mammal spectrograms. CNNs excel at image recognition and can identify features and patterns in images. Spectrograms of marine mammal acoustics can be treated as images and put into a standardized format to be used as an input into a CNN model for classification, allowing for a more structured representation of the data than raw time series. The Marine Mammal Monitoring (M3R) on Navy ranges has an extensive data set of both labeled and unlabeled recordings, online sources such as the Watkins marine mammal sound data base have a smaller extent of data but more accessible labeled data. By taking advantage of these online data sets a robust CNN model can be developed and applied to a subset of M3R data to make classifications of marine mammals on navy ranges.
