Figure 3. Horizontal wavenumber spectra of vertical displacement inferred from digitized reflectors from open ocean (squares), near slope (dots), all scaled by the average buoyancy frequency, N, covering the representative depth range of the chosen reflectors. Vertical bars are 95% confidence intervals. The GM76 tow spectrum is shown as a band for the observed range of N= 1 – 2.5 cph. The dashed line shows the –5/3 slope of the inertial subrange of turbulence, for reference.
