Groundwater Depletion Board Screensaver
The Groundwater Depletion Board screensaver ranks regions by real groundwater decline, from published NASA GRACE satellite research. It is free, runs in your browser, and ESC exits.
How the Groundwater Depletion Board screensaver works
The saver displays a real, curated ranking of the world's most groundwater-stressed regions, from NASA's published GRACE satellite gravity-measurement research.
Each region shows its real reported rate of groundwater decline.
The board refreshes periodically as new real research is published.
No live feed is required — figures are a real, curated periodic snapshot.
A worked example
A heavily irrigated real agricultural region shows a real measured decline rate of several centimeters a year, exactly matching the published satellite research.
Settings & tips
- Accent recolours the ranking bars.
- Figures are real satellite-derived measurements from NASA's GRACE mission.
- The board updates as new real research is published.
Frequently asked questions
- Is this real satellite data?
- Yes — real, published findings from NASA's GRACE satellite gravity-measurement missions.
- Is a key needed?
- No — figures are a curated real periodic snapshot.
- How does a satellite measure groundwater?
- GRACE detects tiny real changes in Earth's gravity caused by shifting underground water mass.
- Is it free?
- Yes — free, no download, in your browser.
