The geoid (the surface of equal gravitational potential of a hypothetical ocean at rest) serves as the classical reference ...
Antarctica sits above the strongest negative gravity anomaly on Earth, a region where the planet’s gravitational pull dips so low that the sea surface sags by more than 100 meters compared to the ...
A persistent "gravity hole" beneath Antarctica gives scientists a window into Earth's deep interior, showing how processes far below reshape the planet's gravity field over millions of years.
