This map shows the movement of two satellite tagged Antarctic blue whales. The track on the bottom right are the movements of one whale over 13 days. The other three tracks capture segments of movement by the second whale over 74 days. The tag for this second whale did not transmit data consistently, resulting in data gaps throughout the tracking period.
The blue portions of track show where the whales were moving quickly and directly, suggesting they were in transit, while the orange locations show where they slowed down and appeared to be searching or foraging.
