University of Michigan aquatic ecologist Donald Scavia and his colleagues say this year's Gulf of Mexico "dead zone" is expected to be larger than average, continuing a decades-long trend that threatens the health of a $659 million fishery. The 2010 forecast, released today by the U.S. National Oceanic and Atmospheric Administration (NOAA), calls for a Gulf dead zone of between 6,500 and 7,800 square miles, an area roughly the size of Lake Ontario.
University of Michigan aquatic ecologist Donald Scavia and his colleagues say this year's Gulf of Mexico "dead zone" could be one of the largest on record, continuing a decades-long trend that threatens the health of a half-billion-dollar fishery. The scientists' latest forecast, released today, calls for a Gulf dead zone of between 7,450 and 8,456 square miles---an area about the size of New Jersey.
The New Jersey-size Gulf of Mexico "dead zone" will likely grow in coming years unless federal policies to control it change, in part because the demand for corn-based ethanol fuel will worsen the problem, University of Michigan scientists say. The dead zone forms each spring off the Louisiana and Texas coast when oxygen levels drop too low to support most life in bottom and near-bottom waters. This summer the oxygen-starved zone swelled to 7,900 square miles, the third-largest Gulf of Mexico dead zone recorded since measurements began in 1985.
On June 8 University of Michigan students and faculty will meet with state and local stakeholders to kick off an innovative project intended to evaluate options for establishing sustainable eco-tourism in northeast Michigan. The Northeast Michigan Integrated Assessment project, coordinated by the Northeast Michigan Council of Governments and the Michigan Sea Grant program, is the largest collaborative effort of its kind in the state, according to Don Scavia, professor and associate dean of the University of Michigan's School of Natural Resources and Environment.
