Figure 9. Net influence of diel diving behaviour on blue shark displacements.

Ocean currents averaged over 4 years at depths of 35 m (A, thin vectors) and 600 m (B). The longest vector corresponds to a speed of 45 cm/s. Displacement vectors associated with the diving behavior are shown at the pop-up locations as bold vectors in A. Note that these displacement vectors are averaged over the full lifetime of the PATs and are normalized to give the change in displacement over a 200 day period. The inset in B shows the zonal velocities through the section indicated by the bold dashed line; solid contours indicate eastward flow while the dashed contour line indicates westward flow.
