A region beneath Antarctica where Earth’s gravitational pull is measurably weaker than anywhere else on the planet has persisted for roughly 70 million years, according to new research that traces the ...

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 ...

Bottom line: There's a well-known "hole" in Earth's gravity field just off India's coastline, known as the Indian Ocean Geoid Low (IOGL). A new study is providing a potential explanation for this ...

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 ...

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 ...
