Antarctica hides Earth’s most extreme gravity hole, and scientists finally know why
A frozen continent at the bottom of the world sits over the deepest dip in Earth’s gravitational pull, a feature that has persisted for roughly 70 million years. Scientists have long known about this ...
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 ...
When we’re told about newly released satellite images of our Earth, we imagine beautiful swathes of green and blue with the occasional white of swirling storm clouds or snow-topped mountain ranges.
The Indian Ocean Geoid Low (IOGL), a significant gravitational anomaly, has puzzled scientists for decades. Research suggests it formed due to interactions between tectonic plates and mantle plumes ...
