The study of the ocean has changed in a fundamental way over the past 50 years. The technological revolution ushered in by the end of the Second World War has revolutionized how we measure and conceptualize the oceans. During my graduate work in the late 1990s, it was still common to have entire quantitative courses devoted to perturbation theoretic approaches, as exemplified by Pedlosky’s classical treatise Geophysical Fluid Dynamics. The very regular oceanic circulations that typify the results of such theories were already known to be largely wishful thinking of the human mind, though it was the worldwide dissemination of the results of the TOPEX/Poseidon satellite that confirmed the notion that the ocean was a field of eddies. In the subsequent decades, the scales of simulation and observations have become even finer, with eddy permitting simulations yielding to true eddy resolving simulations, and the revealed mysteries of the mesoscale supplanted by the emerging complexities of the submesoscale. I believe variants of this story are widely reported and the sentiments widely believed—or as is more typical of academics, not disagreed with too strongly. It is worth pointing out that even without computation, it is possible to present the motion of fluids in an accessible way that is rooted in reality.
