Number of detection hours per day for frequencies above 2 kHz, with detections according to the detector used for clicks, and contours, representing odontocete clicks and high frequency whistles (top). Sound Pressure Level values for different 1/3 octave bands, grouped into six-hour averages for visibility purposes (bottom). Grey segment bars indicate the sampling effort in days (i.e., gaps represent lack of acoustic data).
