From: Predation of archival tagged Dolly Varden, Salvelinus malma, reveals predator avoidance behaviour and tracks feeding events by presumed beluga whale, Delphinapterus leucas, in the Beaufort Sea

Fig. 4

Vertical behaviour of two representative tagged beluga whales over 20 h periods with depths recorded at 75 s intervals within an area (see ‘spatial polygon’ in Fig. 1) used by Canadian anadromous Dolly Varden near the estimated location of the ingested tagged Dolly Varden: a RD2019#18 on 16th July 2019 between 69.06374° N 137.0342° W and 69.5230° N 137.5928° W, and b RD2019#20 on 17th July 2019 between 69.83131° N 137.0729° W and 70.15336° N 137.3574° W, with the arrow denoting the time period (c) when two dives to 48 m completed in 8.75 min and 6.25 min, respectively. Seafloor depth estimated from correlated random walk-modelled locations and the International Bathymetric Chart of the Arctic Ocean (IBCAO) version 3.0 [101], which has a spatial resolution of 500 m
