The Mississippi Sound is a sound along the Gulf Coast of the United States. It runs east-west along the southern coasts of Mississippi and Alabama, from the mouth of the Pearl River at the Mississippi-Louisiana state border to the Dauphin Island Bridge, a distance of about 90 miles (145 km). The sound is separated from the Gulf on its southern side by the Mississippi–Alabama barrier islands: Cat, Ship, Horn, West Petit Bois, Petit Bois, and Dauphin. Ship, Horn, West Petit Bois and Petit Bois Islands are part of the National Park Service's Gulf Islands National Seashore. Those islands separate the sound from the Gulf of Mexico. The sediment of the islands was created partly by the ancient Mississippi River when the St. Bernard Lobe of the Mississippi Delta was active over two thousand years ago. The expansion of the St. Bernard subdelta slowly isolated the Mississippi Sound from ocean dynamics of the open Gulf of Mexico.
Round Island is a small, uninhabited island in the Mississippi Sound, 6.5 kilometres south of Pascagoula, Mississippi, U.S.A. The island is a coastal preserve, situated in Jackson County and managed by the Mississippi Department of Marine Resources. The relatively isolated terrain—consisting of slash pine forest, interior marsh, and sandy beach—provides feeding, resting, and wintering habitat for migratory birds, including the brown pelican, white pelican, and cormorants. A number of rare or endangered species, including the Ruellia noctiflora, are found there.
Ship Island is a barrier island off the Gulf Coast of Mississippi, one of the Mississippi–Alabama barrier islands. Hurricane Camille split the island into two separate islands in 1969. In early 2019, the US Army Corps of Engineers completed the first stage of a project rejoining the two islands and recreating one Ship Island. Ship Island is the site of Fort Massachusetts, as a Third System fortification. Part of the island is included in the Gulf Islands National Seashore.
The Pilot Island Light is a lighthouse located near Gills Rock, on Pilot Island at the east end of Death's Door passage, in Door County, Wisconsin.
Petit Bois Island is a barrier island off the Mississippi Gulf Coast, south of Pascagoula, and one of the Mississippi–Alabama barrier islands. It is part of Jackson County, Mississippi. Since 1971 it has been a part of Gulf Islands National Seashore, administered by the U.S. National Park Service.
Biloxi Lighthouse is a lighthouse in Biloxi, Mississippi, adjacent to the Mississippi Sound of the Gulf of Mexico. The lighthouse has been maintained by female keepers for more years than any other lighthouse in the United States. It was listed on the National Register of Historic Places in 1973 and declared a Mississippi Landmark in 1987.
The Round Island Light, also known as the Old Round Island Point Lighthouse, is a lighthouse located on the west shore of Round Island in the shipping lanes of the Straits of Mackinac, which connect Lake Michigan and Lake Huron. It was deemed necessary because the island is a significant hazard to navigation in the straits, and was seen as an effective complement to the other lights in the area. Because of its color scheme and form — red stone base and wood tower — it has been likened to an old-fashioned schoolhouse. Ferries regularly pass it on their way to Mackinac Island, and it is a recognizable icon of the upper Great Lakes.
Sambro Island Lighthouse is a landfall lighthouse located at the entrance to Halifax Harbour, Nova Scotia, on an island near the community of Sambro in the Halifax Regional Municipality. It is the oldest surviving lighthouse in North America and its construction is a National Historic Event.
Poe Reef is a lighthouse located at the east end of South Channel between Bois Blanc Island and the mainland of the Lower Peninsula, about 6 miles (9.7 km) east of Cheboygan, Michigan.
La Balize, Louisiana was a French fort and settlement near the mouth of the Mississippi River, in what later became Plaquemines Parish. The village's name meant "seamark." La Balize was historically and economically important for overseeing the river. It was rebuilt several times because of hurricane damage. The active delta lobe of the river's mouth is called the Balize Delta, after the settlement, or the Birdfoot Delta, because of its shape.
The Cat Island Light was a lighthouse located on Cat Island off the coast of Mississippi. Originally built to guide shipping through the Mississippi Sound, it was discontinued as traffic moved further south.
The Green Island Light is a lighthouse located on Green Island in Lake Erie, U.S. state of Ohio, to the west of the Bass Islands. Abandoned since its deactivation in 1939, it survives as a hollow shell near the existing skeleton tower.
Round Island Lighthouse stood from 1859 to 1998 on the southwest end of Round Island in the Mississippi Sound, 4 miles (6.4 km) south of Pascagoula, Mississippi. In September 1998, the lighthouse was toppled by Hurricane Georges. In 2010, the base of the structure and other lighthouse remnants were removed from Round Island and relocated within the City of Pascagoula for restoration.
The East Pascagoula River Light was a lighthouse in Pascagoula, Mississippi. A house with a lantern on top, it was first lit in 1854 but was extinguished in the Civil War and was not relit until 1868. It was destroyed in the 1906 Mississippi hurricane and was never rebuilt.
The Pass A L'Outre Light is a defunct lighthouse in the Birdfoot Delta in Louisiana, United States, located near the mouth of the Mississippi River. Erected to mark the then-active entrance to the river, it was abandoned as that channel silted up. It has been in the path of several noteworthy hurricanes, and was heavily damaged. It is on the Lighthouse Digest Doomsday List, and is critically in danger. The lighthouse is at the center of a nature preserve.
The Mississippi–Alabama barrier islands are a chain of barrier islands in the Gulf of Mexico along the coasts of Mississippi and Alabama enclosing the Mississippi Sound. The major islands are Cat Island, Ship Island, Horn Island, Petit Bois Island, and Dauphin Island; in the early 20th century the chain also included the Isle of Caprice, which has since been submerged. The islands are separated by wide inlets, several of which have been channelized to form the shipping channels for Gulf coast ports. The shapes and sizes of the islands have changed significantly since the 1800s, with the islands generally shrinking and shifting westward, especially after major tropical cyclones. Most of the islands are uninhabited. Much of the Mississippi portion of the chain is included in the Gulf Islands National Seashore.
