Remotely operated vehicle Quest 4000 prepares to use a “gas-tight“ vent fluid sampler at a spectacular black smoker vent consisting of a cluster of about 20 active chimneys that was discovered in the Niua South volcano during the Submarine Ring of Fire 2012: Northeast Lau Basin expedition. The expedition team measured the peak temperature at the largest chimney to be 315°C (599°F), consistent with the boiling temperature at that depth.
