Minor errors were identified in the Figures in the original publication:
Arrow heads were included on the geostrophic current vectors in Figure 2 to indicate flow direction in association with velocity but are not visible in the published figure.
There are erroneous references to sharks in Figures 11 (a–f). Labels in the top left corner of ‘Actual whale shark’ maps read: (a) shark 09, (b) shark 10, (c) shark 13, (d) shark 14, (e) shark 15, and (f) shark 16. Correct labels should read: (a) shark 1, (b) shark 2, (c) shark 5 (d) shark 6 (e) shark 7, and (f) shark 8.
