At Land’s Edge – Tracking Coastal Ecosystem with Landsat

Coastal ecosystems store carbon, buffer storms, and shelter marine life—but they’re also among the most threatened environments on Earth. For over 50 years, the NASA–USGS Landsat program has tracked their health, from monitoring Florida’s mangroves after hurricanes to uncovering the surprising growth of eelgrass meadows in Canada. Today, Landsat even powers tools like STREAM, putting coastal water quality data at your fingertips.
