a Temperature and b depth recorded by a pop-up satellite archival tag attached to a Dolly Varden prior to, during, and after predation by a presumed beluga whale in the Beaufort Sea. Numbers on top of panels refer to timing of temperature changes, specified in Table 1. Note that temperature and depth error are based on the TRange and DRange, respectively, values reported in the time-series files, which are a function of the range of temperature and depths encoded in a 6 h message
