Summary: Watch a NOAA video podcast on the Submarine Ring of Fire 2006 (SRoF'06) expedition to the Mariana Arc. While the pilots were trying to tend to a troublesome suction sampler at 560 meters (1840 feet), a large burst from the Brimstone Pit (which clearly has two side-by-side eruptive vents) almost engulfs the vehicle in an ash plume.
