Mudflats or mud flats, also known as tidal flats or, in Ireland, slob or slobs, [1] [2] are coastal wetlands that form in intertidal areas where sediments have been deposited by tides or rivers. A global analysis published in 2019 suggested that tidal flat ecosystems are as extensive globally as mangroves , covering at least 127,921 km 2 ...
Worldwide, continental shelves occupy a total area of about 24 million km 2 (9 million sq mi), 8% of the ocean's total area and nearly 5% of the world's total area. [ 29 ] [ 30 ] Since the continental shelf is usually less than 200 metres deep, it follows that coastal habitats are generally photic , situated in the sunlit epipelagic zone .
Atchafalaya Basin. The wetlands of Louisiana are water-saturated coastal and swamp regions of southern Louisiana, often called "Bayou".. The Louisiana coastal zone stretches from the border of Texas to the Mississippi line [1] and comprises two wetland-dominated ecosystems, the Deltaic Plain of the Mississippi River (unit 1, 2, and 3) and the closely linked Chenier Plain (unit 4).

The Mississippi River Delta is the 7th largest river delta on Earth and is an important coastal region for the United States, containing more than 2.7 million acres (4,200 sq mi; 11,000 km 2) of coastal wetlands and 37% of the estuarine marsh in the conterminous U.S. [1] The coastal area is the nation's largest drainage basin and drains about ...
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
A simplified definition of wetland is "an area of land that is usually saturated with water". [14] More precisely, wetlands are areas where "water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season". [15]
The data for method 2 is from a list maintained by the Office of Ocean and Coastal Resource Management of NOAA. [note 1] The state coastline lengths were computed by an unspecified method that includes tidal areas not included in the first method. [3] These numbers also include the Great Lakes coastlines, which do not have similar tidal areas.
Map of Upper Newport Bay Youngsters wash their horses in Upper Newport Bay, 1975. Photo by Charles O'Rear.. Upper Newport Bay (connected to Newport Harbor via "The Back Bay") is a large coastal wetland (an estuary) in Newport Beach, California, and a major stopover for birds on the Pacific Flyway.
