In 2008, a dead zone was discovered by scientists in the Sound that grew extensively after the oil spill. The likely starting cause is waste nutrients being carried into the estuaries by the
Mississippi River, although the oil made it worse. The dead zone appeared to be created by low amounts of

climate. The average water temperatures range from 70˚F to 84˚F (21–29°C) by month and the humidity ranges between 73% and 84%. Due to the humidity, clouds often form overhead, reducing the amount of daily sunlight that the area receives to as little as 4 hours. The Sound is a part of the

The Sound is accessible to fishermen in both
Mississippi and Louisiana, the two states that border it. Because the Chandeleur Islands protect the Sound from rough seas, ships of all sizes can roam it. Most boats that enter the Sound are used for fishing.
172:. The city of New Orleans itself was founded in 1718 and the Sound has served it for over 300 years. However, fishing was banned across the Gulf Coast for a period of time after the 2010 oil spill, causing the industry to temporarily die out.
144:. The abundance of fish in the sound has helped the region flourish and thrive by allowing humans to settle as early as 1718, when the French arrived in New Orleans. Other fish that can be found in the Sound include, but are not limited to,

Pollution has been a major issue for the region in recent years that has caused wildlife to die as a result of waste being carried in the
Mississippi River and oil spills in the region.
