There may be nothing new under the Sun. But under the deep ice in the McMurdo Dry Valleys of Antarctica, geophysical scientists believe they may have uncovered a previously unknown lacustrine ecosystem, which they have named Lake Vida.Beneath 19 meters of ice—the thickest non‐glacial lake ice cover on Earth—researchers, including Peter Doran of the University of Illinois at Chicago, have reported finding an “ice‐sealed” lake. They concluded that this ice seal distinguishes Lake Vida from other lakes that receive meltwater below a floating ice cover and that annually exchange gases with the atmosphere.
