From: Fin whale (Balaenoptera physalus) migration in Australian waters using passive acoustic monitoring
Mean number of fin whale pulses counted in every normalised 5 min sample averaged over 24 h (a) at the Perth Canyon, WA, (b) Tuncurry, NSW, (c) Dampier, WA. And the number of fin whale pulses recorded in every 1 h sample averaged over 24 h at (d) Cape Leeuwin, WA. Red horizontal lines indicate when recorders were deployed; no recordings were obtained during months without red lines. Note that the Y axis is different for each sampled location.
