NOAA Initiates Three-Year Project on Gulf Dead Zone

The US National Oceanic and Atmospheric Administration (NOAA) has awarded first-year funding of $284,000 to researchers at the University of Texas at Austin Marine Science Institute (UTMSI) as part of a three-year $781,000 project to develop a better understanding of how nutrient pollution from the Mississippi River affects the large area of low oxygen water called the “dead zone” in the Gulf of Mexico.

The project will also look at how the dead zone affects commercially and recreationally important fish and shellfish. Funds were awarded through NOAA’s Northern Gulf of Mexico Hypoxia and Ecosystems Research Program.

A draft report from the Science Advisory Board (SAB) to the US Environmental Protection Agency published earlier this month suggests that changes to the current structure of economic incentives favoring corn-based ethanol may be necessary to prevent a dramatic increase in nutrient loadings in the Mississippi and Atchafalaya River Basin (MARB) that would lead to an expansion of the annual dead zone. (Earlier post.)

The NOAA project will provide data to verify water quality models and help resource managers determine the quantitative relationships between nutrient pollution and development, magnitude, longevity, and distribution of the dead zone. Findings will also support the development of more accurate predictive models of hypoxia development on the Louisiana continental shelf.

The dead zone is an area in the Gulf of Mexico where seasonal oxygen levels drop too low to support most life in bottom and near-bottom waters. It is caused by a seasonal change where algal growth, stimulated by input of nutrients such as nitrogen and phosphorus from the Mississippi and Atchafalaya rivers, settles and decays in the bottom waters. The decaying algae consume oxygen faster than it can be replenished from the surface, leading to decreased levels of dissolved oxygen.

This past summer off the coast of Louisiana and Texas, an area of deep water covering 7,900 square miles was declared hypoxic. It is the third largest Gulf of Mexico dead zone on record since measurements began in 1985, and represents an area approximately the size of the state of New Jersey. Also, it is more than one and a half times the average annual dead zone area measured since 1990, 4,800 square miles. The largest dead zone ever recorded covered 8,494 square miles in 2002.



That's good news.


Another example of the deseastrous consequences of the irresponsible decisions of WB. His target was to produce 15% of domestic gasoline consumption with ethanol from corn. They are producing barely 5% and the damages to the environment are already out of control.


Any way to harvest the algae thereby preventing hypoxia and generating biomass?
Farm state dems have no input on ethanol policy do they?
Is it possible for us to look for left right cooperation zones on this blog again.Or have we devolved into left right verbal cage matches once again?


This could be titled, "Government throws away a million dollars in an attempt to portray itself as concerned about the dead zone in the Gulf of Mexico".
They know what causes it and how to stop it. They've just decided not to.

I'm no fan of W, but fertilizer runoff has been going on for a very long time. Lack of organic matter in the soil is a large part of the problem.


Hi John S....Yeah, Greenpeace squawked about the 'Gulf dead zone' in the 70's & gov't reduced the 'dead zone'. But President Bush was thinking about the 'Mideast dead zone policy', & his corn subsidies promptly resurrected the 'Gulf dead zone zombie'.
