A Map of Freshwater
Read moreFifteen years of satellite data show changes in freshwater around the world. || Freshwater is found in lakes, rivers, soil, snow, groundwater and ice, and is one of the most essential of Earth's resources, for drinking water and agriculture. However, the distribution of freshwater around the planet is changing. Researchers used a pair of satellites called the Gravity Recovery and Climate Experiment, or GRACE, to track freshwater movement over the last fifteen years. The twin GRACE satellites were launched in 2002 as a joint mission between NASA and the German Aerospace Center (DLR). The two satellites precisely measured the distance between themselves to detect changes in Earth's gravity field caused by movements of mass on the planet below, caused by shifts in water and ice. They found that some regions' water supplies are relatively stable, others experienced increases or decreases. Climate change has driven freshwater loss from the ice sheets at the poles, which has implications for sea level rise. Other areas saw groundwater depletions because of humans using water for irrigating crops or increases due to higher amounts of rainfall because of natural variability.

For 15 Years, GRACE Tracked Freshwater Movements Around the World
Read moreNASA scientists used GRACE data to identify regional trends of freshwater movement, and combined that information with data from other satellites, climate models and precipitation measurements to determine the causes of major regional trends in freshwater storage. || The Gravity Recovery and Climate Experiment, or GRACE mission, used precise measurements of the motions of two spacecraft in Earth’s orbit to track the movement of water through the oceans, land, and atmosphere.Music: Iron Throne by Anthony Giordano [SACEM]Complete transcript available. ||
