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 ...
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 ...
