Distribution of the vertical velocity in low-resolution dives. Distribution of the vertical velocity (histogram and density plot [black line]) associated with each broken stick in low-resolution dives for the Weddell seal (a) and the SES (b). The threshold of 0.4 m s−1 was used for both species to discriminate “low speed” (i.e. “huntinglowres”) segments versus “high speed” (i.e. “transitlowres”) segments in low-resolution dive data. The total time spent in “huntinglowres” segments for each dive was used as an index of foraging effort (i.e. “huntinglowres time”)
