Landsat 9 image of San Francisco Bay, California

This natural color Landsat 9 image from December 10, 2021 shows the cities of San Francisco, San Jose, and Oakland surrounding the San Francisco Bay. The bay is the largest estuary on the west coast and includes a patchwork of mud flats, salt marshes, and salt ponds.  The color of the salt ponds is indicative of the salinity levels and the types of microorganisms that thrive in them.
