Yes, scientists have indeed discovered a remarkable underwater environment often referred to as the 'Lost City' in the Atlantic Ocean. While it is not a traditional city built by humans, it is a unique geological formation with towering structures that give it a city-like appearance.
What is the 'Lost City' Hydrothermal Field?
The Lost City Hydrothermal Field is an extraordinary deep-sea environment located beneath the Atlantic Ocean. Discovered by scientists, this area is not an ancient human civilization but an otherworldly geological marvel. It is characterized by massive, carbonate chimneys formed by hydrothermal vents, some of which stand as tall as multi-story buildings, creating a landscape reminiscent of a city skyline. This unique environment also supports a diverse and thriving ecosystem of organisms adapted to extreme conditions.
According to a report by the Times of India, scientists have described the Lost City Hydrothermal Field as an "otherworldly environment with towering structures and a thriving ecosystem" (Exploring 'Lost City' beneath Atlantic Ocean - Times of India).
Key Characteristics of the Lost City
The Lost City Hydrothermal Field possesses several distinct features that make it a significant scientific discovery:
- Location: Situated in the mid-Atlantic, specifically on the Atlantis Massif, a submerged mountain.
- Geological Formation: Unlike black smokers, which are typically found at mid-ocean ridges and emit hot, acidic, metal-rich fluids, the Lost City vents produce warm, alkaline, methane-rich fluids. These fluids react with the seawater to form massive carbonate chimneys.
- Unique Structures: The 'towers' or chimneys can reach heights of over 60 meters (200 feet), creating an intricate, city-like landscape.
- Extreme Ecosystem: Despite the harsh conditions, a vibrant ecosystem flourishes here, sustained by chemosynthesis rather than photosynthesis. Microbes thrive on the chemical energy from the vents, forming the base of a food web that includes various invertebrates.
Why Is It Called the 'Lost City'?
The name 'Lost City' primarily derives from the striking visual appearance of its hydrothermal structures. The tall, white, pillar-like formations, sculpted over thousands of years by the interaction of seawater with the Earth's mantle, resemble buildings or skyscrapers. This resemblance has led scientists and the media to affectionately label it a "city," albeit one forged by geological processes rather than human hands.
Significance of the Discovery
The discovery of the Lost City Hydrothermal Field holds immense scientific importance for several reasons:
- Understanding Life's Origins: Its unique chemistry and energy sources provide insights into how life might have originated on early Earth, potentially in similar alkaline hydrothermal environments.
- Extremophile Research: The organisms found there are extremophiles, offering a window into how life adapts and thrives in environments previously thought to be uninhabitable.
- Planetary Science: Studying the Lost City helps scientists understand potential conditions for life on other planets or moons, such as Europa or Enceladus, which are believed to have subsurface oceans.
- Carbon Cycle: The chemical reactions occurring at these vents play a role in the Earth's carbon cycle, as methane is produced.
