Track lines of harbour porpoises plotted as distances from loudspeaker (metres) relative to time of exposure (minutes). Vertical red stippled lines indicate period of sound exposure and are therefore absent in the four control trials (trial 1-4). Baseline observations (blue), observations made during sound exposure (red) and observations during recovery (green) of harbour porpoises.
