The Earth’s geoid is the shape the planet would assume if its surface were made of water. Naturally, there’s little dispute over the shape of the geoid over the oceans, where it varies by only 100 ...

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 ...

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 ...

Figure 1: Relationship between the geoid and seismic tomography. The best-fitting model (Fig. 2a) was found by a systematic parameter search (Supplementary Figs 1–5). The eastern hemisphere geoid low ...
