On World Water Day, to celebrate this precious and finite resource, we spoke with experts and learned about the importance of groundwater, how our ocean affects us and how one of our upcoming Earth missions will give us a unique perspective on water.

Oceanographer Dr. Matt Archer and Hydrologist Dr. Cedric David talk about how SWOT will change our perspective on water.

One of the things the SWOT mission will do is help scientists track the amount of fresh water in lakes, rivers, and reservoirs, and monitor how they change over time.
