Methane from the bottom of the sea contributes more to global warming than previously assumed. Scientists of the Alfred Wegener Institute for Polar and Marine Research investigated a mud volcano located in the deep-sea between Norway and Svalbard.

[P]Greenhouse gases contribute significantly to present changes of the global climate. Carbon dioxide and methane are major greenhouse gases, whereby methane molecules do 20 times more efficiently prevent reverberation of heat into outer space.

The sources of methane are mos. . .

By means of optical and acoustical observations researchers found a upward water stream induced by the buoyancy of the bubbles. This upward stream transported methane to the ocean surface even beyond the depth of bubble dissolution.


It is interesting that the stream goes beyond the depth of dissolution.

It would appear that we need to place gas collection systems down near these methane sources.
