- Accurate prediction of the distribution of velocities underneath oceanic water waves is of importance in modelling the transport of water-borne debris (wreckage), pollutants (plastics and oil), and sediment. The laboratory experiments reported in this paper provide the first definitive, quantitative and unambiguous demonstration that the mean Lagrangian velocity in the absence of other flows can be accurately calculated from the lowest-order irrotational wave velocity field. Why has it taken 172 years for experimental confirmation of Stokes' theory to be made? It turns out that the experiment is surprisingly hard to do properly (Stanford University's Professor Monismith's comment in doi:10.1017/jfm.2019.891).
