Researchers with NOAA and a consortium of Louisiana universities have been watching a large “dead zone” in the northern Gulf of Mexico for decades, studying its size and impact on marine life and the environment.
Researchers with the National Oceanic and Atmospheric Administration and a consortium of Louisiana universities have been watching this zone for decades, studying its size and impact on marine life and the environment.A “dead zone” is also known as a hypoxic zone. It is an area of significantly reduced oxygen in a body of water.This area cannot support marine life and essentially becomes a biological desert.
This particular “dead zone” runs just off the southern coast of Louisiana, from near Cameron, La. to the mouth of the Mississippi River.The Gulf of Mexico’s “dead zone” is a result of excess nutrients that are being dumped into the Gulf from the Mississippi River.Water from the MS River is partially creating the"Dead Zone" in the northern Gulf of Mexico.
This leaves oxygen levels significantly depleted in the zone, forcing marine life to move elsewhere or die.Scientists have been researching and monitoring the Gulf “dead zone” since the mid-1980s.Researchers inspected the zone in late July and concluded the region has shrunk to approximately 3,058 square miles.While this is good news, it is still a massive area.
The discharge of water from the Mississippi was below the long-term average and also found the salinity of the water in the area to be higher than normal.Reducing the Zone FurtherIn June of last year, the Environmental Protection Agency announced a $60 million program to fund nutrient reduction efforts.
