That's interesting. Perhaps it is due to the larger amount of dissolved gas in
the fluid, or that the fluid is closer to its saturation level in terms of
dissolved gas? I would think that tiny cavitation bubbles from the
negative-pressure component of a pressure waves would almost instantaneously
collapse again in the positive-pressure component, but maybe not. However, I'm
not a fluid engineer, so I'm just speculating.
