2007 Gravity Anomaly Detected Over Atlantic
In 2007, satellites detected a continent-scale gravity anomaly over the eastern Atlantic, caused by deep mass redistribution.
Why it matters
- Reveals dynamic processes deep within Earth's mantle.
- Highlights interconnectedness of Earth's internal and external systems.
- Provides insights into planetary dynamics and behavior of Earth's core and mantle.
By the numbers
- Anomaly duration: 2006-2008, peaking in January 2007.
- Size: 7,000 kilometers across.
- Depth: 3,000 kilometers below the surface.
The big picture
- Anomaly suggests significant mass redistribution deep within Earth.
- Coincided with a geomagnetic jerk, indicating complex interactions between Earth's core and mantle.
- Findings could reshape understanding of Earth's internal dynamics and their influence on surface phenomena.
What they're saying
- Commenters expressed fascination and curiosity.
- Speculations include implications for planetary cooling and chemical processes within Earth.
Caveats
- Findings are yet to be confirmed.
- Frequency and broader implications of such mass redistributions remain unknown.
What’s next
- Further research needed to confirm findings and explore broader implications.
