Antarctic Gravity Anomaly Offers Insights into Earth's Mantle Dynamics

Researchers from the University of Florida and the Institut de Physique du Globe de Paris have studied the Antarctic Geoid Low, a gravity anomaly in Antarctica. Their research traces the anomaly's evolution over the past 70 million years, showing its persistence and intensification. This evolution is linked to slow subterranean flows of rock in the Earth's deep mantle. These mantle dynamics coincide with significant climate changes, including the continent's glaciation period. The study provides new insights into Earth's internal processes and how they influence gravity variations. The findings were published on February 16, 2026, contributing to the understanding of the planet's internal structure and geophysical behavior.
