GLIN==> Earthwatch Radio: Midwest wetland restoration / Gulf of Mexico "dead zone"



Earthwatch Radio Feature Report

Wetland Restoration in the Midwest, Hypoxia Relief in the Gulf of Mexico


Every year, the Gulf of Mexico suffers a water quality problem of
extraordinary proportions that creates a vast "dead zone," an expanse of
water that's deficient in oxygen and dangerous for marine life.  Some
experts say the "dead zone" would cover less of the gulf if healthy
wetlands covered more of the Upper Midwest. They say wetlands could
partially remove one of the major forms of pollution that leads to the
depletion of oxygen in the Gulf of Mexico every spring.

Earthwatch Radio presents an online article on the role of nitrates in
this "dead zone" with a special focus on the way nitrates move through
groundwater and how wetland restoration might help clean them up.  The
article is based on interviews with faculty at the University of
Wisconsin-Madison who specialize in the study of groundwater and the
restoration of wetland ecosystems.

The article is on the Earthwatch Radio web site at:

Nelson Institute for Environmental Studies at the University of
