In A Nutshell Antarctica, not the Indian Ocean, hosts Earth’s strongest nonhydrostatic geoid depression when scientists ...

According to a new study, researchers have identified a massive gravity hole-technically known as a Geoid Low-beneath the Antarctic ice surrounding the Southern Ocean. This discovery is providing ...

Antarctica sits above the strongest negative gravity anomaly on Earth, a region where the planet’s gravitational pull dips so low that the sea surface sags by more than 100 meters compared to the ...

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

Gravity field modeling and geoid determination are critical tasks in geodesy and Earth sciences, providing insights into the Earth’s mass distribution and its gravitational potential. Researchers ...

AMAZING GRACE Data collected by the twin Gravity Recovery and Climate Experiment (Grace) satellites have produced the most accurate map yet of Earth's geoid, or gravity field, even before the ...

After accounting for Earth’s rotation, gravity is slightly weaker beneath Antarctica than anywhere else on the planet. That weakness creates a kind of “gravity hole,” a broad low in the field that ...

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 ...

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