AI Overview
The image depicts the “Lost City” Hydrothermal Field, a remarkable and unique underwater environment located deep in the Atlantic Ocean.
Oldest Known Hydrothermal System:
It is the oldest known active hydrothermal vent field in the ocean, estimated to have existed for at least 120,000 years.
Unique Structure:
The field is characterized by towering mineral formations, primarily composed of carbonate, which give it an “urban” appearance, hence the name “Lost City”.
Origin of Life Clues:
Scientists believe the extreme conditions within the Lost City, including its unique chemistry and high pH levels, may hold clues to understanding how life first emerged on Earth.
Unique Ecosystem:
Despite its deep-sea location, the Lost City supports a unique ecosystem of microbial communities that thrive in the absence of oxygen, utilizing hydrocarbons produced by the chemical reactions within the vents.
Conservation Efforts:
Due to its scientific significance and unique nature, some experts are advocating for the Lost City to be designated as a World Heritage site to protect it from potential threats like deep-sea mining.
When I saw “hydrothermal field”, I immediately thought mid-Atlantic ridge. But this is OFF Cuba, so is there really a hydrothermal field close of Cuba? At over 600 meters, this is very deep. However, we do have the history of the serious sinking of Port Royal caused by a severe earthquake several centuries ago. However, that was less than 100 feet. On the other hand it was only centuries ago, not millennia ago.
I have visited several very old Central American and Mexican urban ruined cities. Some well restored, or perhaps not even that ruined, and my impulse is to say these photos, if not manufactured, “feel” like ancient remains to me. Of course this is not scientific findings, just my gut. ;-)
