That is fine, Curt, I have no shortage of bubbles.
I have been fooled by nature sounding artificial many times. Of course the

so)from this recording location. The increasing interest in drones for police
and hobbyists is likely increasing the pressure of anthropogenic presence on
natural soundscapes.
