Acceleration data from a blacktip reef shark

This file contains the dataset analysed in the associated publication under section "Real data examples", subsection "Diel activity changes in a reef-associated shark"

Depth, swimming speed, spectrogram of lateral acceleration (indicative of fin movements) where magnitude was expressed by color, pitch (red line), and roll (blue line) of an ocean sunfish (mass, 48 kg).

<p>Open circles on the spectrogram represent dominant stroke cycle frequencies calculated for each five-minute time bin. Positive pitch represents head-up attitude of the fish, while negative pitch indicates head-down attitude. Positive roll represents right-rotated position of the fish, while negative roll indicates left-rotated position.</p

Lateral (red line) and longitudinal (blue line) accelerations recorded from an ocean sunfish (mass, 48 kg).

<p>(A) Typical examples. The vertical broken lines delineate the separation of the stroke cycle. (B) Power spectral density (PSD) calculated from the entire data set of this individual. Arrows indicate peaks.</p
