Fig. 8. Body acceleration (grey dots) and pitch (red dots) as a function of depth.
Values are shown in the first 200 m of the water column and thus only show
data for descent (A) and ascent (B). Positive acceleration is always in the
direction of forward motion of the body. Thick lines represent the mean of
each respective parameter at a particular depth. The orange vertical line
denotes the mean depth where gait transition from fluking to gliding occurs
during descent (21±7 m, N=28) and during ascent (30±5
m, N=28).
