Summary
Example spectra for the Tidal shelf high-quality dataset. About 3h worth is shown, and each spectrum was constructed from 128 s (2.13min) worth of data, which was split into FFT-length of 32 s (2048 samples). The speeds past the sensor vary from a minimum of 0.3 m/s and a maximum of 0.8 m/s. The combination of high [math]\displaystyle{ \varepsilon }[/math] and fast speeds enables using short segments to compute the spectra. The impact of turbulence anisotropy is also visible with the flattening of the spectra at wavenumbers around 1 cpm.
