Groundwater in movement

Groundwater in movement

This visualization shows how water mass is constantly changing around the world.

Each circle shows water height anomaly for that location compared to its long-term average. White circles represent water gain while empty circles represent water loss, the bigger the circle, the higher the gain or loss.

The visualization is a part of a submission for HeadsUP! Times Square Visualization Challenge. A full description of the submission can be found at

Extremely interesting. Recently a study on how Australia trapped an unusual amount of water in 2011 made headlines and how that supposedly caused a lowering of the global sea level. It’s amazing how dynamic our planet is.
