Notes on Vent Field Description:
steep-walled, 50-m-wide cylindrical crater on the north flank, about 75 m below the summit, is at least 135 m deep and was observed to emit cloudy hydrothermal fluid; During a NOAA expedition in 2006, scientists observed Cauldron, a convecting, black pool of liquid sulfur with a partly solidified, undulating sulfur crust at a depth of 420 m below the summit of Daikoku, and temperature > 200 C; located within U.S. Marianas Trench Marine National Monument (http://www.fws.gov/marianastrenchmarinemonument/)
Notes Relevant to Biology:
extensive biological communities with new species tonguefish, tubeworms, snails, and crabs (NOAA cruise report 2006)
Year and How Discovered (if active, visual confirmation is listed first):
2004 ROV ROPOS; 2003 plume only
