MapTheCloudsDay 38. Visualizing gravity beneath Antarctica 🧊
What does gravity look like at Earth’s most remote continent?
3D map of gravity disturbances using the EIGEN-6C4 model (0.1°). Data from Quantarctica reveals how ice thickness, bedrock density, and subglacial topography shape the field.
Processed in QGIS. Warmer elevations = positive anomalies, cooler depressions = negative ones.
Not the surface, but the forces beneath it.
