Red circles show the location and size of many dead zones (in 2008). Black dots show dead zones of unknown size. The size and number of marine dead zones—areas where the deep water is so low in dissolved oxygen that sea creatures cannot survive (except for some specialized bacteria)—have grown in the past half-century.

Dead zones occur in the ocean when phosphorus and nitrogen from fertilizers in land runoff cause excessive growth of microorganisms, which depletes oxygen and kills fauna. Worldwide, large dead zones are found in coastal areas with high human population density.
“Sharks of the Dead Zone,” which premieres at 9 p.m. Friday as part of Discovery’s Shark Week, sounds a bit frightening.And it is, if you care about the health of our planet. The host of the ...
A 'dead zone' off the Gulf coast is larger than NOAA predicted. The massive area poses danger to marine life, and recovery could take decades. A 'dead zone' is growing in the Gulf of Mexico.
The Oregon coast is known for its stunning beauty. "Our family fishing boat, the Timmy Boy, has just come in from a trip fishing for sablefish," says fisherman Bob Eder. Eder says this abundant ...
The ultimate cause of hypoxia is excess nutrient loading from human activities causing algal blooms. The blooms sink to the bottom and use oxygen to decompose at a rate faster than it can be added back into the system through the physical processes of mixing. The lack of oxygen kills bottom-living organisms and creates dead zones.
Every spring, an area appears when the water doesn't have enough oxygen to support fish and other marine life. The Gulf of Mexico's 'dead zone' is the biggest on record Skip to main content
