Fig. 3: Comparison of Sound Pressure Levels, broadband and in the “shipping bands”, in different seasons.
From: Marine soundscapes of the Arctic and human impacts: going beyond the “shipping bands”
Boxplots showing the variation of Sound Pressure Levels, broadband (10 Hz–32 kHz, top) and for the third-octave bands of 63 Hz (middle) and 125 Hz (bottom), for the months of August (left) and May (right). Months with not enough acoustic data are not represented. The red lines go through the mean values of each plot. For statistical reasons, only the first four weeks of each month are represented.
