Maps showing the telemetry tracks for (A) chinstrap penguins (N = 74) and (B) southern elephant seals (N = 315), colored by the distance from the tagging location. The tagging locations are shown in red. The Polar Front (dashed line) and the southern boundary of the Antarctic Circumpolar Current (solid line), as provided by Orsi et al. (1995), are plotted for reference.The light gray box denotes the focus area between 55°S and 65°S and 110°W and 165°W. Maps were generated with R software, version 4.1.1.
