Mississippi Sound : ウィキペディア英語版
Mississippi Sound

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 Waveland, Mississippi, to the Dauphin Island Bridge, a distance of about 145 kilometers (90 mi). The sound is bordered on its southern edge by the barrier islands - Cat, Ship, Horn, Petit Bois and Dauphin Islands - which 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.〔Velardo, Brian. (May 2005) "Detailed Geochronology of the Mississippi Sound during the Late Holocene." Thesis-Master of Sciences. Department of Oceanography and Coastal Sciences. Louisiana State University. Baton Rouge, Louisiana.p. 62. Retrieved December 6, 2014. http://etd.lsu.edu/docs/available/etd-04072005-210612/unrestricted/Velardo_thesis.pdf 〕
Traditional seafood harvests, particularly shellfish, have been curtailed recently due to declines in numbers and quality caused by pollution and weather related events such as hurricanes, flooding, or droughts. Federal and state authorities have various programs and regulations aimed at shellfish restoration and water quality monitoring for beachgoers.〔EPA. Water Quality at Gulf Coast Beaches. Gulf of Mexico Program. Stennis Space Center, MS. Retrieved December 6, 2014. http://www.epa.gov/gmpo/wqgulfcoast.html〕〔EPA. Gulf of Mexico Shellfish Challenge. "Implementing Priority Projects". Gulf of Mexico Program Office. Stennis Space Center, MS 39529-6000. Retrieved December 6, 2014. http://www.epa.gov/gmpo/pubhealth/priority_proj.html 〕
Large portions of the Mississippi Sound reach depths of about 6 meters (20 ft). Part of the Gulf Intracoastal Waterway traverses the sound with a project depth of 3.6 meters (12 ft). The waterway, maintained by the US Army Corps of Engineers, is designed for towboat and barge traffic. Most of its route through the sound is merely an imaginary line through water whose depth exceeds the project depth. A section west of Cat Island and the portion north of Dauphin Island rely on dredged channels marked by aids to navigation maintained by the US Coast Guard.
Deepwater ports along the sound include Gulfport and Pascagoula. Dredged ship channels running basically north-south connect those ports to the Gulf of Mexico, running between pairs of the barrier islands.
The Pascagoula River and the Pearl River flow into the sound.〔''Merriam-Webster's Geographical Dictionary, Third Edition'', p. 750.〕
