A team of scientists just discovered a hydrothermal system that’s 100 times larger than the famously massive Lost City system in the Atlantic Ocean. This time, researchers discovered a vast hydrothermal system that they have since dubbed the Kunlun system. The Kunlun system’s discovery comes years after researchers found the “Lost City” system in the Atlantic Ocean. While the Lost City hydrothermal field is no lost city of Atlantis, it’s still remarkable—in fact, it may be the longest-lived venting environment in history. But what the Lost City has in years, the Kunlun system has in size.
