Tidal marshes are wetlands that are covered with incoming tidal water twice a day. These marshes may be as small as narrow fringe along a tidal creek or miles across in estuaries with adjacent flat landscapes. There are nearly 40 million acres of tidal marshes along the Atlantic, Gulf, and Pacific shores of the U.S. The Soil Science Society of America's (SSSA) January 1st "Soils Matter" blog explores how tidal marshes store carbon and why they are an important part of surrounding landscapes.
