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

After accounting for Earth’s rotation, gravity is slightly weaker beneath Antarctica than anywhere else on the planet. That ...

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

Antarctica sits above the strongest negative gravity anomaly on Earth, a region where the planet’s gravitational pull dips so ...

The ground may feel steady underfoot, but the planet is always in motion. While satellites and sensors have mapped the surface in fine detail, what lies beneath remains largely unknown. The crust, a ...

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

A huge, mysterious so-called “gravity hole” under the Indian Ocean might have been formed from the remnants of an ancient sea, according to a new study. Researchers recently offered the possible ...

For years, researchers have tried to pinpoint how an area deep in the Indian Ocean with lower gravitational pull came to be. A team in India may have figured it out. The area in question is called the ...
