Barrier islands are a coastal landform, a type of dune system and sand island, where an area of sand has been formed by wave and tidal action parallel to the mainland coast. They usually occur in chains, consisting of anything from a few islands to more than a dozen. They are subject to change during storms and other action, but absorb energy and protect the coastlines and create areas of protected waters where wetlands may flourish. A barrier chain may extend for hundreds of kilometers, with islands periodically separated by tidal inlets. The largest barrier island in the world is Padre Island of Texas, United States, at 113 miles (182 km) long. Sometimes an important inlet may close permanently, transforming an island into a peninsula, thus creating a barrier peninsula, often including a beach, barrier beach. Though many are long and narrow, the length and width of barriers and overall morphology of barrier coasts are related to parameters including tidal range, wave energy, sediment supply, sea-level trends, and basement controls. The amount of vegetation on the barrier has a large impact on the height and evolution of the island.
Perdido Key State Park is a 247-acre (1.00 km2) Florida State Park located on a barrier island fifteen miles (24 km) southwest of Pensacola, off S.R. 292, in northwestern Florida. The address is 12301 Gulf Beach Highway.

Laguna de Términos is the largest tidal lagoon by volume located entirely on the Gulf of Mexico, as well as one of the most biodiverse. Exchanging water with several rivers and lagoons, the Laguna is part of the most important hydrographic river basin in Mexico.

Kemp's ridley sea turtle, also called commonly the Atlantic ridley sea turtle, Kemp's ridley turtle, and Kemp's ridley, is a species of turtle in the family Cheloniidae. L. kempii is the rarest species of sea turtle and is the world's most endangered species of sea turtle. It is one of two living species in the genus Lepidochelys. The species L. kempii primarily occupies habitat around the Gulf of Mexico, though its migrations into the Atlantic Ocean are being affected by rising temperatures. Kemp's ridley sea turtle is listed as endangered under the Endangered Species Act (ESA), and conservation efforts are attempting to rebuild population numbers. Human activity, including but not limited to habitat destruction, climate change, and oil spills, threaten populations.

Padre Island is the largest of the Texas barrier islands and the world's longest barrier island. The island is located along Texas's southern coast of the Gulf of Mexico and is noted for its white sandy beaches. Meaning father in Spanish, it was named after Father José Nicolás Ballí (c.1770-1829), who owned the island and served as a missionary priest and collector of finances for all the churches in the Rio Grande Valley. He also founded the first mission in present-day Cameron County.

The Florida district of the Gulf Islands National Seashore includes the east end of the island, as well as other Florida islands. No more than a few hundred yards wide in most places, Perdido Key stretches some 16 miles (26 km) from near Pensacola to Perdido Pass Bridge near Orange Beach.
Mustang Island is a barrier island on the Gulf Coast of Texas in the United States. The island is 18 miles (29 km) long, stretching from Corpus Christi to Port Aransas. The island is oriented generally northeast–southwest, with the Gulf of Mexico on the east and south, and Corpus Christi Bay on the north and west. The island's southern end connects by roadway to Padre Island. At the northern end of the island is Port Aransas, beyond which is San José Island. The Aransas Channel, also known as the "Aransas Pass," which separates Mustang Island from San José Island, is protected by jetties extending into the Gulf from each island.
Pea Island National Wildlife Refuge is a national wildlife refuge located on North Carolina's Pea Island, a coastal barrier island and part of a chain of islands known as the Outer Banks, adjacent to Cape Hatteras National Seashore. The sanctuary is located 10 miles (16 km) south of Nags Head, North Carolina on NC 12.
North Padre Island is a barrier island along the coast of Texas. It and South Padre Island were formed after the creation of the Port Mansfield Channel split Padre Island in two. From north to south, North Padre Island is located in parts of Nueces, Kleberg, Kenedy, and Willacy counties.

The Laguna Madre is a long, shallow, hypersaline lagoon along the western coast of the Gulf of Mexico in Nueces, Kenedy, Kleberg, Willacy and Cameron Counties in Texas, United States. It is one of seven major estuaries along the Gulf Coast of Texas. The roughly 20-mile (32 km) long Saltillo Flats land bridge divides it into Upper and Lower lagoons joined by the Intracoastal Waterway, which has been dredged through the lagoon. Cumulatively, Laguna Madre is approximately 130 miles (210 km) long, the length of Padre Island in the US. The main extensions include Baffin Bay in Upper Laguna Madre, Red Fish Bay just below the Saltillo Flats, and South Bay near the Mexican border. As a natural ecological unit, the Laguna Madre of the United States is the northern half of the ecosystem as a whole, which extends into Tamaulipas, Mexico approximately 144 miles (232 km) south of the US border, to the vicinity of the Rio Soto La Marina and the town of La Pesca, extending approximately 275 miles (443 km) through USA and Mexico in total.
The U.S. state of Texas has a series of estuaries along its coast on the Gulf of Mexico, most of them bounded by the Texas barrier islands. Estuaries are coastal bodies of water in which freshwater from rivers mixes with saltwater from the sea. Twenty-one drainage basins terminate along the Texas coastline, forming a chain of seven major and five minor estuaries: listed from southwest to northeast, these are the Rio Grande Estuary, Laguna Madre, the Nueces Estuary, the Mission–Aransas Estuary, the Guadalupe Estuary, the Colorado–Lavaca Estuary, East Matagorda Bay, the San Bernard River and Cedar Lakes Estuary, the Brazos River Estuary, Christmas Bay, the Trinity–San Jacinto Estuary, and the Sabine–Neches Estuary. Each estuary is named for its one or two chief contributing rivers, excepting Laguna Madre, East Matagorda Bay, and Christmas Bay, which have no major river sources. The estuaries are also sometimes referred to by the names of their respective primary or central water bodies, though each also includes smaller secondary bays, inlets, or other marginal water bodies.
Port Mansfield Channel or Mansfield Cut is an artificial waterway encompassing the Laguna Madre positioned at the 97th meridian west on the earth's longest barrier island known as Padre Island. During Post–World War II, the tidal inlet was dredged as a private channel differentiating North Padre Island better known as Padre Island National Seashore and South Padre Island. The navigable waterway was channeled during the late 1950s ceremoniously cresting the intertidal zone of the Gulf of Mexico by September 1957 on the Texas Gulf Coast.
