Figures & data
Fig. 1 Location and photograph of fixed platform.
Fig. 2 Example spectra of velocity fluctuations for 8-min record, where S v corresponds to that of vertical velocity, partitioned into wave motion and turbulence parts. S h corresponds to that of the horizontal velocity, which was multiplied by a factor of 100 for clarity. A fit to S v in the inertial subrange is overlaid.
