Perched near the summit of an underwater mountain close to the Mid-Atlantic Ridge, the Lost City Hydrothermal Field emanates an intriguing tale of exploration, resilience, and impending perils.
Unveiled in 2000, the Lost City Hydrothermal Field lies more than 700 meters below the ocean surface, enveloped in enigma. This venting environment, enduring for at least 120,000 years, unveils the distinctive interplay between the upsurging mantle and seawater, a narrative unparalleled in the ocean’s depths.
Despite its extreme setting, life flourishes in the Lost City. The vents expel hydrogen, methane, and gases that sustain robust microbial communities thriving in the absence of oxygen, as reported by Science Alert. From snails to crustaceans, a diverse array of creatures inhabit its chimneys, illustrating the adaptability of life in unconventional ecosystems.
Offering a glimpse into extraterrestrial habitats, the hydrocarbons emitted by the Lost City’s vents raise curiosity, hinting at potential parallels to habitats on celestial bodies like Enceladus, Europa, or Mars.
In stark contrast to black smokers, conventional underwater volcanic vents, the Lost City’s calcite vents defy expectations. They generate abundant hydrogen and methane, deviating from the mineral-rich emissions of black smokers. The considerable size of these vents suggests a rich history and prolonged activity.
However, the allure of the Lost City extends beyond scientific curiosity, attracting commercial interests. In 2018, Poland secured mining rights in the vicinity, posing a significant threat to this delicate ecosystem. Scientists sound the alarm about potential plumes and discharges resulting from mining activities, emphasizing the urgent need to protect the Lost City.
A chorus of urgent appeals resonates for its designation as a World Heritage site, a plea aimed at safeguarding this underwater marvel from the irreversible impacts of mining and environmental degradation.
