Salt marsh during low tide, mean low tide, high tide and very high tide (spring tide). A coastal salt marsh in Perry, Florida, USA.. A salt marsh, saltmarsh or salting, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides.
Sea salt being added to raw ham to make prosciutto. Salting is the preservation of food with dry edible salt. [1] It is related to pickling in general and more specifically to brining also known as fermenting (preparing food with brine, that is, salty water) and is one form of curing.
Inland salt marshes are quite rare and have unique conservation needs, yet there is a severe lack of research on these ecosystems. Protected by the European Natura 2000 network [ 8 ] and classified as a G1 category endangered ecosystem, [ 1 ] there is a strong need to protect these rare, decreasing ecosystems, yet a lack of available research ...
Salt marshes can be generally divided into the high marsh, low marsh, and the upland border. The low marsh is closer to the ocean, with it being flooded at nearly every tide except low tide. [53] The high marsh is located between the low marsh and the upland border and it usually only flooded when higher than usual tides are present. [53]
Outwelling is a hypothesized process by which coastal salt marshes and mangroves, “hot spots” of production, produce an excess amount of carbon each year and “outwell” these organic nutrients and detritus into the surrounding coastal embayment or ocean, thus increasing the productivity of local fisheries or other coastal plants.
Brackish marshes develop from salt marshes where a significant freshwater influx dilutes the seawater to brackish levels of salinity. This commonly happens upstream from salt marshes by estuaries of coastal rivers or near the mouths of coastal rivers with heavy freshwater discharges in the conditions of low tidal ranges .

Salt marshes are dominated by specially adapted rooted vegetation, primarily salt-tolerant grasses. [8] Salt marshes are most commonly found in lagoons, estuaries, and on the sheltered side of a shingle or sandspit. The currents there carry the fine particles around to the quiet side of the spit, and sediment begins to build up.
