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.
An international team looks back 12 million years for clues about the formation of these vast areas where no life can survive A satellite image of the Northern Gulf of Mexico, where 'dead zones' can ...
The dead zone in the Gulf has been monitored for the past 32 years. It stretches from the mouth of the Mississippi River into Texas and is created each year by low oxygen levels in water, or hypoxia.
The global science community is watching the problem of oxygen depletion in marine and coastal areas with growing concern. Over the last few years the number of known dead zones globally has increased ...
When the oxygen levels go down, dead zones will expand. These are areas of the ocean where the water quality is too poor to sustain life. Pollution will only add to the devastation unless we stop it.
The study identifies nutrient pollution, industrial runoff, and urban wastewater as primary contributors to algal blooms in ...
