Fig. 4From: Fine-scale foraging movements by fish-eating killer whales (Orcinus orca) relate to the vertical distributions and escape responses of salmonid prey (Oncorhynchus spp.)Comparative swim speeds between the three identified dive types made by 30 tagged northern resident killer whales (F = foraging, R = respiration, O = other behaviors; N = 11,319 total dives from 31 tag deployments). Whole dive velocity was calculated by dividing the 3-dimensional dive path length (determined using dead-reckoning) by the total dive time, and included both descent and ascent phases. Vertical velocities for descent and ascent phases were based solely on depth sensor dataBack to article page
