There is a “gravity hole” in the Indian Ocean — a spot where Earth’s gravitational pull is weaker, its mass is lower than normal, and the sea level dips by over 328 feet (100 meters).

Called the Indian Ocean Geoid Low (IOGL), it features an enormous dip in the ocean’s surface, dropping 106 meters lower than surrounding areas. This "gravity hole" has baffled scientists for ...

There’s a massive “hole” in the Indian Ocean, researchers say—but it’s not the kind that could drain away all that water. Instead it’s a term geologists use to describe a spot where ...

This phenomenon, known as the Indian Ocean Geoid Low, is the largest gravitational hole on the planet and has puzzled scientists for decades. A geoid is a theoretical representation of the Earth in ...

An animal that burrowed horizontally through the sea floor might have made these linear holes, says a marine zoologist Credit: NOAA At over 8,000 feet beneath the Atlantic Ocean, scientists ...

The “gravity hole” in the Indian Ocean — officially called the Indian Ocean geoid low — is the lowest point in that geoid, forming a circular depression that starts just off India’s ...
