Dr. Nancy Rabalais, who has devoted her life to the study of dead zones in the Gulf of Mexico, has been chosen for the prestigious MacArthur Fellows Program, which comes with a no-strings-attached $500,000 prize paid out over five years. The 62-year-old marine ecologist is executive director of the Louisiana Universities Marine Consortium in Cocodrie.
The MacArthur Foundation’s stipends, often called a “genius grant,” are awarded to people “of outstanding talent to pursue their own creative, intellectual and professional inclinations.” Twenty-three people were chosen for the 2012 awards, which the foundation says are not for past accomplishment, but rather an investment in a person’s originality, insight and potential. In other words, a fitting award for Nancy Rabalais.
Rabalais’ research is dedicated to documenting and mitigating the effects of hypoxic zones — aquatic areas with low dissolved oxygen levels commonly known as “dead zones” — that have expanded dramatically in the Gulf of Mexico and many other coastal systems around the globe. Rabalais received her bachelor’s and master’s of science degrees from Texas A&I University in Kingsville and a Ph.D. from the University of Texas. Since 1983, she has been affiliated with the LUMS. Her scientific articles have appeared in such journals as Science, Nature, BioScience, and Biogeosciences.
According to the foundation’s website:
Since the mid-1980s, [Rabalais] has led a long-term monitoring program to study the size, intensity, and seasonal occurrence of dead zones in the waters off the Louisiana continental shelf; she has also analyzed the relationship between the extent of hypoxia and the increasing quantities of nutrients such as nitrogen and phosphorus flowing into the Gulf from the Mississippi River watershed.
When concentrated in coastal waters, the nutrients from farmland fertilizer and other sources spur the growth of an overabundance of algae, the decomposition of which consumes oxygen vital to sustaining an enormous spectrum of aquatic species. Over the past three decades, Rabalais’s studies have evolved to include collaborations with researchers from many different disciplines and have used methods from physical oceanography, hydrology, geochemistry, and paleoecology to make ever more precise assessments of hypoxia dynamics and their impact on a range of fragile, interconnected ecosystems.
In addition to her scientific contributions, Rabalais has played a prominent role in informing strategies to restore the degraded waters of the Gulf by reducing nutrient pollution from urban and agricultural runoff upstream and has focused national attention on the environmental and economic consequences of large-scale eutrophication. Her outreach efforts have included lecturing throughout the United States about the effects of hypoxia on those far from its waters, testifying before Congress, and working with federal, state, and tribal agencies on an action plan for improving water quality in the Mississippi River basin.
While weathering the destruction of her research facility in catastrophic hurricanes and treacherous diving conditions due to oil spills, Rabalais continues to deepen our understanding of this profound oceanographic problem that threatens the well-being of the entire Gulf region.

JUL 25 Elliott Stonecipher writes about his specialty in this post on Forward Now: numbers. He's running down Louisiana's poverty numbers, and they aren't good. There has been progress, he says, but can we build on it? And is poverty in Louisiana inevitable?
JUL 25 Jim Brown is blogging about the death penalty this week. In particular, he's discussing a really, really good reason to stop using it: too many people who aren't guilty are being convicted and sentenced to death.
JUL 25 Blogger Tom Aswell has crafted a fascinating analysis in this post. He's discussing Bobby Jindal and his cross-country, pre-presidential pandering, but he weaves in a historical perspective by reviewing FDR's New Deal and Huey Long's resistance to it - which also was because Huey planned to run for President.
JUL 25 Education Superintendent John White probably shouldn't sign a long lease on anything in Louisiana, Blogger Lamar Parmentel writes, because our reformer in chief is now in a situation "from which no amount of his own bs jargon or political hatchet work can extricate him." Lamar thinks that White is going to have to quit, and probably sooner rather than later.
JUL 25 Blogger Ian McGibboney gives his take on that study that found the happiest cities are right here in Louisiana, including Lafayette, Baton Rouge and Shreveport. (Really. I know, right?) As he says, it is all about perspective: One can be happy in a toxic dump and miserable at Disney World.
JUL 25 Blogger Rod Dreher writes about Christianity in this post, examining the concept of traditional or orthodox as it relates to his religion. Since Dreher is a conservative, orthodox Christian, it's not an objective discussion, but it's certainly an interesting read, if for no other reason than to seek understanding.
JUL 25 If you're not aware, there's a conflict among pro-choicers and pro-lifers going down in New Orleans. Anti-abortionists are protesting in the city this week, but those who support access to abortion have also been active in the city as a result. MSNBC's Rachel Maddow takes a look at what's going on in this clip, posted on Gambit.
JUL 25 This post on the Wall Street Journal examines the case of a Metairie physician who is making millions by filing whistle-blower lawsuits. His suits accuse corporations of defrauding federal agencies like Medicare, and when he wins he gets whistle-blower rewards - in the tens of millions of dollars. (You can view the story using your Facebook account, but if you don't want to do that, here's an abbreviated version in the Advocate.)
JUL 24 The Lens is hosting a panel discussion on the cost of coastal restoration, and who should pay for it, next month in NOLA. It is planned to be a discussion of the realities of the coastal restoration master plan and its current funding, as well as what the future holds.
JUL 24 This post on the Red Stick Blog reveals nine facts about Mike the Tiger, the LSU mascot who turns nine this week. That's interesting and all, but the best part of the post is the video of Mike playing around with a visitor, just like any other kitty. A massive, deadly, 400-pound, roaring kitty.
JUL 24 The recent articles about a study that found America's happiest cities are here in Louisiana have produced some raised eyebrows among those who have actually been to Shreveport and Baton Rouge. But the Today show did some research, and produced this article which talks about stuff that doesn't really represent those two cities. Are we still going with the drunk, fat and stupid brand?
