White smokers at NW Eifuku submarine volcano that were photographed by a NOAA expedition in 2006. The bubbles are carbon dioxide; this is one of two places where natural liquid carbon dioxide emission has been observed. It is a small submarine volcano about 1,500 m below the ocean surface that displays vigorous thermal activity.
