Activity seascapes for grey reef sharks at Palmyra atoll. a The volume of probability of diel activity determined from accelerometers shown in a space-time cube, where each voxel gets the value of respective probability based on the time in the voxel. Darker/lighter green voxels in the probability volume correspond to higher/lower probability values in the chart. b Space-time density volume for grey reef sharks (n = 17). The bottom panel shows the projection of the volume onto the two geographic dimensions, i.e. the map of Palmyra atoll. Note that this is a view from above the 3D UD volume and not a 2D UD surface. c Activity seascape for grey reef sharks (n = 17). The bottom panel shows the projection of the volume onto the map of Palmyra atoll. Voxel size in all volumetric representations is 100 m × 100 m × 10 min, creating a Space-Time volume of 202 × 56 × 144 voxels (20.2 km × 5.6 km × 24 h)
