Depth weighting plays an essential role in 3-D potential-field inversion to counteract the decay of the kernel function of gravity or magnetic potential fields, making the recovered results more ...

Abstract: Human activity intensity prediction is crucial to many location-based services. Despite tremendous progress in modeling dynamics of human activity, most existing methods overlook physical ...

Gravitational anomalies detected by NASA and the German Aerospace Center’s GRACE satellites confused scientists for years. These anomalies are fluctuations in gravity, and while they were suspected to ...

For decades, scientists have been studying intriguing “gravity holes,” which are enormous depressions in the Earth’s crust where the effects of gravity are significantly lower than average. It’s an ...

Earth’s gravity variations result from differences in rock density in the mantle, far below the surface. These differences are subtle and not readily noticeable by humans. “From the gravity reduction, ...

Antarctica landscape. Credit: Wikimedia Commons. We tend to think of gravity as being about as constant as it gets. It is the invisible anchor that keeps our feet on the ground and the oceans in their ...

We treat gravity as a firm law, but the ground beneath Antarctica tells a different story — one where the planet’s internal churn is actively weakening its grip. A new study led by the University of ...

A weak-gravity region under Antarctica may have evolved alongside major climate changes, hinting that Earth’s deep interior could shape sea level and ice-sheet growth in unexpected ways. Credit: ...
