Exemplary hourly median depth time series (A) and corresponding wavelet scalogram (B). In B significant wavelet powers (p ≤ 0.05) are highlighted with grey contours. In A the upper bar indicates the presence (dark grey) or absence (light grey) of diel vertical migration (DVM) behaviour, based on significance (p ≤ 0.05) of wavelet powers at 24h
