Spectrograms for slow-down pulse train (sd3) (a) from Stellwagen Bank (site 4) and (b) from Jacksonville 2 (site 8) (see Figure 2 for overview map). Spectrogram parameters: fast Fourier transform (FFT): size = 512 points, overlap = 75%, sample rate = 2000 Hz, resolution = 3.9 Hz and 64 ms. Y-axis starts at 0.03 kHz to remove low-frequency noise. Spectrograms made with Seewave [59].
