Fourteen years ago, deep beneath the Atlantic Ocean’s surface, scientists made a groundbreaking discovery: a hydrothermal field known as the ‘Lost City.’ This unique underwater landscape, located west of the Mid-Atlantic Ridge, is like nothing ever seen before. Towering rocky structures rise from the ocean floor, some reaching heights of nearly 200 feet, creating a surreal, otherworldly environment. These towering chimneys and walls, believed to be over 120,000 years old, emit gases at 104°F, contributing to a thriving ecosystem in one of the most inhospitable places on Earth.1
A Unique Ecosystem
Despite the extreme conditions, the Lost City is teeming with life. Microbial communities have thrived here for millennia, feeding on the hydrothermal vents’ hydrogen, methane, and other gases. These tiny organisms have formed the basis of an entire ecosystem, supporting snails, crustaceans, and even larger creatures like crabs, shrimp, and eels.
The Lost City stands apart from other known hydrothermal fields, such as the famous black smokers, which are typically associated with volcanic activity. Unlike these, the Lost City’s hydrothermal vents are not fueled by magma but by chemical reactions occurring deep within the Earth’s mantle. This difference results in the production of hydrocarbons, which are crucial building blocks for life. Some scientists suggest that similar ecosystems might exist on other celestial bodies, like Saturn’s moon Enceladus or Jupiter’s moon Europa, raising the intriguing possibility that life could thrive in similar environments beyond Earth.2

The Threat of Deep-Sea Mining
The Lost City, however, faces significant threats. In 2018, Poland secured the rights to explore 10,000 square kilometers around the Mid-Atlantic Ridge for deep-sea mining. While the actual hydrothermal field may not contain valuable minerals, the surrounding areas do. The concern among scientists is that mining activities could disturb the delicate balance of this unique environment, potentially causing irreversible damage.
Dr. Gretchen Fruh-Green, one of the lead scientists involved in the Lost City’s discovery, has expressed concern that mining could destroy this ancient and valuable site before we fully understand its significance. “We could destroy this place before we’ve understood it,” she warned, emphasizing the potential loss not only for Earth’s history but also for our understanding of life’s origins and its potential existence elsewhere in the universe.
A Call for Protection
Given the Lost City’s unique characteristics and its importance to science, there have been calls to protect the area from human activities, particularly deep-sea mining. Some experts have even suggested that the Lost City should be designated as a World Heritage site, ensuring its preservation for future generations and preventing any industrial activities that could jeopardize this natural wonder.

The Future of the Lost City
For now, the Lost City stands as a testament to the resilience and adaptability of life in the most extreme environments. It also serves as a reminder of the delicate balance that exists in these remote ecosystems and the impact human activities can have on them. As exploration of the deep sea continues, the Lost City remains a focal point of scientific interest, offering insights into both our planet’s history and the potential for life beyond it. The hope is that with increased awareness and international cooperation, the Lost City can be protected and studied for years to come.
