Although Earth is approximately spherical, its gravity field doesn't adhere to the same geometry. In visualizations, it more closely resembles a potato, with bumps and divots. One of the strongest of ...

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.

Scientists have finally explained the Indian Ocean Geoid Low, a massive gravity anomaly south of India. New research reveals this 'gravity hole' formed over millions of years due to hot, less dense ...

A new study has reconstructed the evolution of the planet’s strongest nonhydrostatic geoid depression —the Antarctic Geoid ...

"The ocean surface is definitely not flat. It is constantly changing as wind, waves and swells produce surface undulations, daily tidal fluctuations raise and lower the average height." ...

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

Antarctica is home to many mysteries, but one of the strangest is an enormous 'gravity hole' deep beneath the ice. Now, ...

Forte and colleagues now believe Antarctica’s gravity hole was weaker before eventually intensifying around 30 to 50 million ...

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

A peer-reviewed study published in Scientific Reports has reconstructed the evolution of the Antarctic Geoid Low, the strongest negative gravity anomaly on Earth, over approximately 70 million years, ...
