TABLE I.

Overview of the data set used to train and test ERMA. It comprises a subsample of the data set for the Third International Workshop on the Detection, Classification and Localization of Marine Mammals Using Passive Acoustics, Boston, MA, USA; published online at www.MobySound.org. All recordings are sampled at 96 kHz and 16-bit resolution.
