    Scientists sent underwater robots into the depths of the Pacific, about 1.5 miles (2.5 kilometers) beneath the surface, and discovered something unexpected: a football field-size expanse of towering hydrothermal vents that cropped up in an area these underwater chimneys haven't typically been seen.

    The hydrothermal vents, shaped like candelabras, stand roughly 35 to 40 feet (10 to 12 meters) tall, or about as tall as three-story buildings, the research team leaders, from Lehigh University, said in a statement.

    These striking structures gush black, mineral-filled water that reaches temperatures(opens in new tab) of up to 694 degrees Fahrenheit (368 degrees Celsius), although the water likely starts out at an even higher temperature, closer to 818 F (437 C), the team determined.

    Such high temperatures hint that a volcanic eruption may occur at the site in the next few years.

    The newfound vent field is located about 200 miles (321 km) off the coast of western Mexico, in the East Pacific Rise, a range of underwater volcanoes that extends nearly from the Gulf of California to Antarctica.

    Researchers surveyed hydrothermal vents in the Pacific using temperature loggers manufactured by EP Oceanographic.

    The loggers collect data every ten minutes, in order to track changes in vent fluid temperature that can be used to infer changes in permeability of the crust beneath the vent.

    Using a remotely operated vehicle, researchers found towering white columns emitting geysers of clear shimmering liquid with temperatures up to 290 degrees Celsius.

    The superheated water flowing from these vents starts deep underground.

    As the hot water rises, it flows through and reacts with the surrounding bedrock, becoming saturated with carbonate minerals, which build up over time to form the large chimneys that were observed.
