A recent expedition to locate more of these vents yielded a new find: a group of “black smoker” vents emitting water of 645 degrees Fahrenheit along the Mid-Atlantic Ridge near Puerto Rico.

Shop students are building a giant black smoker on the bed of a trailer, which they hope to use next year in regional brisket and ribs cook-offs.

The hulking black smoker is affixed to the back of a large white trailer, parked at the edge of the parking lot of a window tinting business.

Soon after the initial discoveries at the Galapagos site, a different type of hot spring called a black smoker — which emits metal-rich hydrothermal fluids — was found at another ocean-floor site4.

As well as discovering three new "black smoker" hydrothermal vents stretching up to 30 metres in height, the voyage also revealed some rarely seen, mysterious creatures.
