Satellite Sees River Flow Across the Globe – Photo of the Day Jan 29, 2025
What the Photo of the Day Reveals On January 29, 2025, satellite imagery captured a striking view of river flow patterns around the world. This “photo of the day” spotlights how scientists monitor discharge—the amount of water moving past a point each second—as a key indicator of flood risk, drought stress, and ecological health. From…

Satellite Eyes on Global River Discharge: Photo of the Day (Jan. 29, 2025)
Overview: A Global Snapshot of River Discharge On January 29, 2025, satellites captured a striking view of rivers worldwide, revealing the diverse patterns of river discharge—the volume of water moving past a point each second. Scientists measure discharge to translate a general sense of river height into precise numbers that help forecast floods, manage drought,…

Progressive Asymmetric Surface Mass Loading: A Hypothesis for Northern Hemisphere Accumulation
Introduction to the Hypothesis The idea of progressive asymmetric surface mass loading proposes that the Northern Hemisphere is gradually accruing surface mass at a higher rate than the Southern Hemisphere. This concept does not claim a sudden tectonic crustal thickening, but rather a persistent imbalance in surface loads that could influence regional gravity, ocean circulation,…

Antarctica Glacier Calving: Underwater Tsunamis Explained
What triggers underwater tsunamis? When glaciers around Antarctica fracture and calve, massive blocks of ice plunge into the deep. This sudden displacement of seawater can generate powerful, long-wavelength waves that travel beneath the ocean surface. Unlike typical surface waves, these underwater tsunamis move with unique motion, spreading energy horizontally and sometimes surfacing as noticeable surges…
