Salt Marsh SOS
In a scientist’s photomosaic taken in 1972, wetlands along the Five Mile River included a small island surrounded by thin ribbons of water and covered grasses that typify a healthy New England salt marsh. In a contrasting set of photos from 2000, all that remains of the island is a puddle-pocked mudflat. The photographs depict a troubling phenomenon along the U.S. Atlantic and Gulf Coasts: Tidal wetlands that have been healthy for hundreds, if not thousands, of years are rapidly breaking up and converting to open water.
