Dead zones occur in coastal areas around the nation and in the Great Lakes — no part of the country or the world is immune. The second largest dead zone in the world is located in the U.S., in the northern Gulf of Mexico.
Q. Where is the dead zone in the Gulf of Mexico?
The zone occurs between the inner and mid-continental shelf in the northern Gulf of Mexico, beginning at the Mississippi River delta and extending westward to the upper Texas coast. The Gulf of Mexico dead zone varies in size annually, but may extend from the Louisiana/Alabama coast to the westernmost Texas coast.

Q. What is the dead zone in the Gulf of Mexico caused by?
The annual Gulf of Mexico dead zone is primarily caused by excess nutrient pollution from human activities in urban and agricultural areas throughout the Mississippi River watershed.
Q. How do dead zones form?
Dead zones begin to form when excess nutrients, primarily nitrogen and phosphorus, enter coastal waters and help fertilize blooms of algae. Major nutrient sources include fertilizers, wastewater, and the burning of fossil fuels.
Q. What is the largest dead zone in the United States?
Gulf of Mexico
Q. Where is the biggest dead zone in the US located and how much area does it cover?
June outlook foretold New Jersey-sized area of low oxygen Scientists have determined this year’s Gulf of Mexico “dead zone,” an area of low oxygen that can kill fish and marine life, is 8,776 square miles, an area about the size of New Jersey. It is the largest measured since dead zone mapping began there in 1985.
Q. Where is a hypoxic zone in the Gulf of Mexico what are its effects?
The hypoxic zone in the northern Gulf of Mexico is an area along the Louisiana-Texas coast, where water near the bottom of the Gulf contains less than two parts per million of dissolved oxygen, causing a condition referred to as hypoxia.
Q. Which year had the largest dead zone?
The 2015 “Dead Zone” measured 16,760 square kilometers (6,474 square miles). This size is larger than the predicted range made in June. Researchers suggest that heavy rains in June and high river discharges in July may provide an explanation for the larger zone measurement.
Q. How far down does the dead zone go?
The edges of the playable area, the Crater, stretch downwards to a depth of 1120 meters. At that point, the world cuts off on most ends. Underneath the Inactive Lava Zone and Lava Lakes, the map stretches farther to 1920 meters.
Q. What can be done to prevent dead zones?
Conservation tillage: Reducing how often fields are tilled reduces erosion and soil compaction, builds soil organic matter, and reduces runoff. Managing livestock waste: Keeping animals and their waste out of streams, rivers, and lakes keep nitrogen and phosphorus out of the water and restores stream banks.
