“…Given the logistical challenges of observing animals within the dynamic nature of polar environments, the application of animal telemetry devices has revolutionized our understanding of the movement ecology of marine species (Hussey et al, 2015). Telemetry data have provided novel insights into complex, previously unknown behaviours, including predator-prey interactions (Breed et al, 2017), fishing fleet interactions with fishes and seabirds (Queiroz et al, 2016;Rolland, Barbraud, & Weimerskirch, 2008;Tuck, Polacheck, Croxall, & Weimerskirch, 2001), environmental drivers of habitat use (Amélineau et al, 2018;Block et al, 2011;Raymond et al, 2015), species diversity hotspots (Grecian et al, 2016) and identifying critical conservation areas (Dias et al, 2017;Lascelles et al, 2016;Ramos et al, 2017). Traditionally, telemetry studies on Arctic marine predators have focused on single or a few species.…”
