Fig. 2. Data from a male bird dive. (A) Diving behavior and total surge
acceleration (YG), (B) the low frequency component of surge (YL) that was
given by filtering total surge (YG) using a two-band low-pass filter, and the
body angle (
=arcsineYL+logger attachment angle
) and (C) the
high frequency component of surge (YH) that was given by subtracting the low
frequency component of surge (YL) from total surge (YG).
