Fig. 3: Timing of bubble events relative to low-frequency pressure fluctuations.
From: Turbulence-induced bubble nucleation in hydrothermal fluids beneath Yellowstone Lake
A subset of the low-frequency (filtered between 2 and 40 Hz) pressure signals (a, blue), and the corresponding pressure rate (b, black), aligned by time of bubble nucleation (red lines), showing that bubble nucleation preferentially occurs at the time of maximum decompression rate. The amplitudes have been normalized by removing the mean and dividing by the standard deviation.
