At Land’s Edge – Tracking Coastal Ecosystem with Landsat

For more than 50 years, satellites in the NASA–USGS Landsat program have been quietly documenting the fragile edge where land meets sea. Their long view has revealed both decline and resilience: mangroves in Florida struggling to recover after hurricanes, eelgrass meadows in Canada expanding against global trends, and shifting coastlines that hold clues to our future. Now, with tools like NASA’s STREAM, that perspective is available to anyone, offering a rare chance to see how coastal ecosystems — and the planet itself — are changing over time. Watch the short informative video from NASA’s Goddard Space Flight Center below.
