Hydrothermal Vents
The Hot Spot Below Yellowstone Park
WHOI scientist Rob Sohn brought an arsenal of deep-sea technology normally used to explore the seafloor to the bottom of Yellowstone Lake, where a team of researchers investigated the subsurface geothermal activity hidden from view in the national park.

Since 1982, I had spent most of my waking hours examining pieces of seafloor vent deposits that had been recovered during a routine dredging operation along the Juan de Fuca Ridge off the Pacific Northwest coast.

In 1985, Cindy Van Dover, then a graduate student in biology in the MIT/WHOI Joint Program, discovered a novel light-sensing organ on a unique species of shrimp that lives at high-temperature, black smoker chimneys on the Mid-Atlantic Ridge. If this photoreceptor were indeed some sort of primitive “eye,” the question instantly arose: At depths of some 3,600 meters, where sunlight cannot penetrate, what are these shrimp looking at? The search for a source of light in deep-sea hydrothermal environments began.

Diving along the mid-ocean ridge at 21°N on the East Pacific Rise, scientists within the deep submersible Alvin peered through their tiny portholes two decades ago to see an astonishing sight: Clouds of billowing black “smoke” rising rapidly from the tops of tall rocky “chimneys.”

Just over 20 years ago, scientists exploring the mid-ocean ridge system first made the spectacular discovery of black smokers—hydrothermal chimneys made of metal sulfide minerals that vigorously discharge hot, dark, particulate-laden fluids into the ocean.
