The Indian Ocean holds the lowest gravity anomaly on Earth, a vast and subtle depression in the planet’s gravitational field located south of Sri Lank.

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 ...

It is found in the depths of Indian Ocean and named as the gravity hole or Indian Ocean geoid low, an anomaly on earth where gravity is said to be weaker, and levels of sea dip by more than 328 feet ...

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 ...

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.

[UPDATE (April 5, 2011): It turns out some of the descriptions I used below to describe a geoid were not accurate. I refer you to this page at the University of Oklahoma for a good description. I’ve ...

The region of lower gravity, discovered in 1948, manifests as a vast depression in the ocean's surface that reaches some 348 feet deep at its greatest extent. A mysterious “gravity hole” in the Indian ...
