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

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 ...

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

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 ...

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

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

Earth, in most renderings, is a smooth sphere with a glossy complexion—a blue marble, as pictures snapped from space have shown us. Earth scientists know that’s not exactly true. Earth, in fact, is an ...

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