The methane bubble wells up off Redondo Beach from time to time. I live in Torrance, right next door. One day I noticed a natural gas smell and also that the gas stove flames were higher and more active, somehow. I called the Gas Co. and was told about the bubble. The Gas Co. had enough calls that they could track its movement by noting the location and timing of the households that had called them.
So, yeah. The ocean passes gas from time to time.
Your post makes no sense at all.
