Minimize Salin Aigues-Mortes

Since antiquity, workers have harvested salt from the tidal marshes of Aigues-Mortes, France—a coastal Mediterranean town steeped in history. Today, salt remains an important industry here, and satellites can provide a bird's eye view of the vibrant production process.

The Operational Land Imager (OLI) on Landsat 8 acquired this natural-color image on August 20, 2018, around the time of peak harvest. Salt from nearby marshes is mechanically harvested for industrial, chemical, and pharmaceutical uses. Salt marshes at Aigues-Mortes also produce a culinary delicacy—a fragile, flaky crystal harvested by hand.
