- 18:2118:21, 5 July 2022 diff hist +616 N File:Anisotropy.png Example of how turbulence anisotropy influenced the spectral shapes. This instrument was located very close to the bed (0.15 m) in a shallow waterway less than 2 m deep, which results in the vertical velocity's inertial subrange being reduced by the flattening of the spectra at wavenumbers of 10 cpm (0.1m scales). Strong stratification is another mechanism that shortens the inertial subrange at the lower wavenumbers. The wavenumber at which i... current

- 17:4117:41, 5 July 2022 diff hist +533 N File:SegmentAnisotropyLowE.png Example spectra for the Under-ice MAVS dataset. About 17h worth of segments are shown, and each spectrum was constructed from 1024 s (17.06 min) worth of data, which was split into FFT-length of 512s (4096 samples). The speeds past the sensor are of the order of a few cm/s. The combination of low <math>\varepsilon</math> and low speeds requires using relatively long segments to compute the spectra. The spectra are also impacted by vibrations and vortex shedding that are contaminating the meas... current

- 16:3516:35, 5 July 2022 diff hist +425 N File:Segment anisotropy.png 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>\varepsilon<\math> and fast speeds enables using short segments to compute the spectra.

Only the example of 1min (480 samples at 8Hz sampling) are illustrated. Removing chunks of 8 continuous samples (1s) looks identical to the original time series and is not illustrated. current
