A global view of the Pacific Ring of Fire.

The Submarine Ring of Fire 2006 (SRoF'06) expedition will take place on the Mariana Arc, the third OE expedition to the Marianas. The image shows a global view of the Pacific Ring of Fire. The 4 previous Submarine Ring of Fire expeditions are indicated at Explorer Ridge, Kermadec Arc and the Mariana Arc. The dashed line is the crest of the Mid-Ocean Ridge system and solid lines show plate boundaries defined by island arcs and trenches. Click image for larger view and image credit.


Submarine Ring of Fire 2006

April 18 - May 13, 2006

The 2006 Submarine Ring of Fire expedition is the third in a series of explorations of the submarine volcanoes lying along the Mariana Arc, extending from south of the island of Guam northward more than 800 nautical miles (1450 km). We discovered some amazing places in 2004, including an erupting volcano (NW Rota-1), liquid CO2 venting (NW Eifuku), the shallowest yet discovered "black smoker" chimneys (East Diamante) and more than 12 new species of chemosynthetic organisms at hydrothermal vent sites. All of us came away from the 2004 expedition with a lingering sense of awe that such amazing places remain undiscovered on Earth, which underscores the value of a national ocean exploration program. We are eager to revisit some of these sites and to make the first dives at several new sites.

Please join us on another voyage of discovery along the Mariana Arc!
