An extended dive trace from ZcTag036 including periods with and without both types of MFAS use. Dives are depicted using duration, maximum depth, and shape as reported from the Behaviour Log; the whale's precise location in the water column at a given point in time was not known. MFAS use at any point in the dive is indicated by colour: red for high-power MFAS, blue for mid-power MFAS, and purple for both types. Distance to the nearest MFAS source is indicated by shaded blocks of time along the x-axis: dark grey for sources within 25 km, medium grey for sources from 25-50 km, and light grey for sources beyond 50 km (maximum distance in this sample was 109 km).
