Vibration-coherent noise removal

All platforms vibrate. The shear-probe, like nearly all other velocity sensors, measures the velocity of the fluid relative to the platform that holds the probe. Thus, platform vibrations induce a signal that is due to platform motions and does not represent environmental shear. The algorithm described by Goodman et al (2006) is often used to remove vibration-induced components from shear-probe spectra. However, this removal biases the spectrum low, in a wavenumber-independent manner, and must be corrected (Lueck et. al., 2021c).
