From high resolution to low resolution: concordance of within-dive parts of intensified foraging effort. High-resolution dive profile (black line) were summarised by the optimal broken stick method (a Weddell seal, c SES) and degraded in SRDLs low-resolution dives (b Weddell seal, d SES). Red lines represent “huntinghighres” (highly sinuous parts of high-resolution dives) and “huntinglowres” (segments associated with vertical velocity ≤0.4 m s−1 of low-resolution dive) mode broken stick segments for high and low resolution, respectively. Conversely, blue lines represent “transithighres” (straighter parts of high-resolution dives) and “transitlowres” (segments associated with vertical velocity >0.4 m s−1 of low-resolution dive) mode broken stick segments for high and low resolution, respectively. Dotted lines represent the 80 (orange) and 60 % (green) of maximal dive depth. The green dots indicate prey capture attempts for the SES dataset (estimated from high-resolution acceleration data)
