Fig. 2. Flow noise increases with body speed. The relationship between flow noise,
measured by the hydrophone, and speed, calculated from the kinematics of the
body, is shown for each whale (MnA, gray; MnB, black) during steep glides
(–30 deg.
pitch
30 deg.). The relationship between flow noise and
body speed was consistent among whales; each line represents a quadratic
regression through the data from each whale (MnA, r2=0.76;
MnB, r2=0.84).
