This is the Champagne vent at NW Eifuku volcano, where bubbles of liquid CO2 escape from the white chimneys and surrounding sea floor. The chimneys are about 20 cm (8 in) across and 50 cm (20 in) high, and they are venting fluids at 103ºC (217ºF). Image courtesy of Submarine Ring of Fire 2004 Exploration, NOAA-OE.
