This movie shows the discovery of Champagne vent at northwest Eifuku volcano, where bubbles of liquid carbon dioxide are actively venting from sea-floor hot springs. This unusual phenomenon is due to the fact that the emissions from NW Eifuku volcano are particularly gas-rich. The high pressure at this depth keeps the carbon dioxide in a liquid state. Champagne vent is at a depth of 1,607 m (nearly 1 mi deep). Video courtesy of Submarine Ring of Fire 2004 Exploration, NOAA Vents Program.
