  • Revising my original post 😉

    The content of the graphic is quite interesting but suffers from a few flaws that are unfortunately common in papers.

    Australia looks invisible because the colour choices were likely made to highlight the routes of the high profile species in the North Pacific and Atlantic. If you look at the individual species at the bottom we’ve got a bit more of a presence there, despite a lack of tracks in our region.

    Also as you pointed out they very much laid it out in such a way as to emphasize certain geographies, despite the high importance of the southern ocean to many whale species. I need to go back and see where the tagging was done, as northern whales seem to be to be over represented in the tracks. It looks like most likely in close proximity to Monterey Bay in California, if I had to guess. Admittedly if the data had come from an Australian institution, it would likely be biased to data collected here.

    I’d also be very interested in seeing this same data laid out with a split northern/southern hemisphere map, from the perspective of the poles.
