Dealing with Dead Zones: Hypoxia in the Ocean
Description: Hypoxic zones are areas in the ocean where the oxygen concentration is so low that animals can suffocate and die, and as a result are often called "dead zones." The largest hypoxic zone in the United States, and the second largest hypoxic zone worldwide, forms in the northern Gulf of Mexico adjacent to the Mississippi River. Runoff from farms and cities drains into the Mississippi. This runoff contains an overabundance of nutrients from fertilizers, wastewater treatment plants, and other sources. This nutrient pollution eventually ends up in the Gulf of Mexico, leading to the formation of hypoxic "dead zones."
