These vents are located off Mexico's western coast.
Scientists sent underwater robots into the depths of the Pacific, about 1.5 miles 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 newfound vent field is located about 200 miles 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. Most hydrothermal vents discovered on the East Pacific Rise have been found along the"axis" of the ridge — the plate boundary where the spreading occurs — where magmatic activity has formed a 54- to 109-yard-wide trough. By comparison, the newfound vent field was discovered about 820 yards east and 4.3 miles north of these previously known vents.
