Subterranean Ocean Discovery : In a groundbreaking discovery, scientists from Northwestern University have unearthed a vast reservoir of water hidden deep within the Earth’s mantle, challenging conventional theories about the planet’s water cycle. This subterranean ocean, three times the size of all the Earth’s oceans combined, lies approximately 700 km beneath our feet, locked within ringwoodite—a blue-coloured rock—a finding that prompts a re-evaluation of Earth’s geological processes.
Scientists Uncover Enormous Ocean 700 km Beneath Earth’s Surface: A Paradigm Shift in Water Cycle Theory
The magnitude of this hidden sea prompts a re-evaluation of Earth’s water cycle, suggesting a potential departure from theories positing comet impacts as the primary source.
The scientific endeavor behind this revelation was led by Steven Jacobsen, a researcher at Northwestern University, who asserts, “This constitutes significant evidence supporting the notion that Earth’s water originated internally.
Unveiling this underground ocean involved deploying an extensive network of 2000 seismographs across the United States, scrutinizing seismic waves emitted by over 500 earthquakes. These waves, traversing through Earth’s inner layers including its core, experience deceleration when passing through damp rock, indicating the presence of this extensive water reservoir.
This discovery potentially reshapes our understanding of Earth’s water cycle, proposing that water may exist within the mantle, migrating amid rock grains. Jacobsen stresses the reservoir’s significance, highlighting its role in maintaining water beneath Earth’s surface, without which water would predominantly reside on the planet’s surface, rendering only mountain peaks visible.
With this groundbreaking revelation in hand, researchers are eager to collect additional seismic data globally to ascertain the prevalence of mantle melting. Their findings hold the promise of revolutionizing our comprehension of Earth’s water cycle, offering fresh perspectives on one of the planet’s fundamental processes.
This discovery challenges existing notions about the origin of Earth’s water and opens up new avenues for research into the planet’s geological processes. Stay tuned for further updates as scientists delve deeper into this fascinating discovery and its implications for our understanding of Earth’s inner workings.
