“It is the lowest geoid/gravity anomaly on Earth and so far no consensus ... but they don’t provide a more precise measure of how well they match numerically (in the study).

The Indian Ocean "gravity hole" is Earth's deepest geoid low. Its weak gravitational pull makes sea levels here 348 feet lower than average, creating a 1.2-million-square-mile anomaly southwest of ...

Earth's deepest gravitational anomaly, known as the "gravity hole," lies 1,200 km southwest of India in the Indian Ocean. Spanning 3.1 million square kilometres, this region's sea level is 348 ...
