A broad low in Earth’s gravity field beneath Antarctica, known as the Antarctic geoid low, is not a sudden oddity. New reconstructions suggest it has persisted for about 70 million years and has been ...

A region beneath Antarctica where Earth’s gravitational pull is measurably weaker than anywhere else on the planet has persisted for roughly 70 million years, according to new research that traces the ...

A shifting of Earth’s poles, referred to as ‘True Polar Wander,” combined with the sinking of tectonic plates during the Cenozoic Era, altered the planet’s interior, with rising hot mantle material ...

According to a new study, researchers have identified a massive gravity hole-technically known as a Geoid Low-beneath the ...

A persistent "gravity hole" beneath Antarctica gives scientists a window into Earth's deep interior, showing how processes ...

Scientists have finally explained the Indian Ocean Geoid Low, a significant gravity anomaly, linking its formation to deep Earth processes and ancient tectonic plate movements.

The geoid (the surface of equal gravitational potential of a hypothetical ocean at rest) serves as the classical reference ...

A mysterious gravity dip beneath Antarctica is growing stronger, shaped by deep Earth forces over millions of years.

One of the strongest of these depressions – where the gravity field is weaker – lies under Antarctica. Now, new models of how the so-called Antarctic Geoid Low evolved over time have shown that it's ...

Why is Antarctica frozen? It is in the polar region, which is one explanation. But something deep underneath the continent ...

This strange 'gravity hole' beneath Antarctica could help explain how its ice and oceans changed over millions of years.

Learn how Antarctica’s gravity hole formed inside Earth and grew stronger as its ice sheets took hold.
