Explanation:
Detailed explanation-1: -Salinity ranges from high saline conditions near a seawater body, towards more brackish tidal marshes located within estuaries near river mouths. Salt marshes have an average salinity between 18.0 and 35.0 ppt; a salinity below 0.5 ppt is considered as tidal freshwater marsh (Odum 1988).
Detailed explanation-2: -The saltiest ocean water is in the Red Sea and in the Persian Gulf region (around 40‰) due to very high evaporation and little fresh water inflow.
Detailed explanation-3: -by salt water (annual average salinity >18ppt). Dominated by saltwater cordgrass and salt hay, it looks grassy. Brackish Tidal Marsh has salinity levels between fresh-and salt water (0.5-18 ppt).
