Fig. 5. An animation showing variation in predicted density of fin whales at each iteration. White patches within the regions of high density reflect grid squares predicted to have >0.22 fin whale schools/nm2. The longest axis of the prediction grid (from the southern tip of South America to the northern tip of the Antarctic Peninsula) is approximately 500 nm long. Note that the area predicted to have the highest density of fin whale schools showed more variability than was seen in humpback whales (Fig. 2), but was always predicted to lie in offshore waters, running parallel to the Antarctic Peninsula.
