Home ranges over time for five humpback whales instrumented with Platform Transmitting Terminals (PTTs). The PTTs were deployed during January 2012, and recorded locations for varying durations (112692 – 65 days; 112699 – 140 days; 112701 – 81 days; 112703 – 38 days; 112705 – 52 days). Home ranges were calculated every 5th day, for the period covering all five PTTs (3 January 2012 through 14 June 2012) as the 95th percentile of the product kernel utilization distribution (UD). Home ranges were larger, more spread out, and further from the mainland in January (a) and February (b), then begin to decrease in total area, spread, and distance to mainland during March through June (panels c - f). A black line shows the shoreline used to calculate distance from mainland for the centroid of each UD.
