At this year's American Geophysical Union (AGU), researchers are highlighting how an ice-measuring mission is helping to understand aspects of our home planet far beyond what it was intended to do.

Launched on a Falcon 9 rocket Nov. 21, the U.S.-European satellite will measure the world's ocean with unprecedented accuracy.

High-tide flooding is an increasing fact of life for U.S. coastal areas. A new tool developed with NASA funding projects its annual frequency for 97 U.S. cities and how it will change over time. (Image credit: B137, CC BY-SA 4.0, via Wikimedia Commons)
