Satellite analysis tracks carbon cost of coastal erosion

From Texas to Maine, coastal wetlands and marshes are releasing more than 1.45 billion pounds (660,000 metric tons) of carbon into the ocean each year, according to new research supported by NASA. Coastal marshes, like forests and tundra, store large amounts of carbon in their plants and soil, but changes caused by storms, rising seas and human development can affect how that carbon is stored and transported.
