Submarine Ring of Fire 2004: NW Eifuku Volcano, Extraordinary Champagne Vent
Update: 2007-07-20
Description
Watch a NOAA video podcast on the Submarine Ring of Fire 2004 (SRoF'04) expedition to the Mariana Arc. This movie shows the discovery of the 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. Scientist discovered th Champagne vent at a depth of 1,607 meters (5272 feet more than 1 mile deep). Video courtesy of Submarine Ring of Fire 2004 Exploration, NOAA Vents Program, NOAA-OE.
