International SWOT Satellite Spots Planet-Rumbling Greenland Tsunami – NASA

Data from space shows water tilting up toward the north side of the Dickson Fjord as it sloshed from south to north and back every 90 seconds for nine days after a 2023 rockslide. The international Surface Water and Ocean Topography (SWOT) satellite mission, a collaboration between NASA and France’s CNES (Centre National d’Études Spatiales), … Read more

International SWOT Mission Can Improve Flood Prediction – NASA

A partnership between NASA and the French space agency, the satellite is poised to help improve forecasts of where and when flooding will occur in Earth’s rivers, lakes, and reservoirs. Rivers, lakes, and reservoirs are like our planet’s arteries, carrying life-sustaining water in interconnected networks. When Earth’s water cycle runs too fast, flooding can result, … Read more

NASA-Led Study Provides New Global Accounting of Earth’s Rivers – NASA

The novel approach to estimating river water storage and discharge also identifies regions marked by ‘fingerprints’ of intense water use. A study led by NASA researchers provides new estimates of how much water courses through Earth’s rivers, the rates at which it’s flowing into the ocean, and how much both of those figures have fluctuated … Read more

SWOT Satellite Helps Gauge the Depth of Death Valley’s Temporary Lake – NASA

Data from the international Surface Water and Ocean Topography mission helped researchers to calculate the depth of water in this transient freshwater body. California’s Death Valley, the driest place in North America, has hosted an ephemeral lake since late 2023. A NASA-led analysis recently calculated water depths in the temporary lake over several weeks in … Read more

See SWOT Mission’s Unprecedented View of Global Sea Levels – NASA

This animation shows global sea level data collected by the Surface Water and Ocean Topography satellite from July 26 to Aug. 16. Red and orange indicate higher-than-average ocean heights, while blue represents lower-than-average heights. Image Credit: NASA/JPL-Caltech Data on sea surface heights around the world from the international Surface Water and Ocean Topography mission yields … Read more
