Lower nitrogen losses with perennial biofuel crops

Perennial biofuel crops such as miscanthus, whose high yields have led them to be considered an eventual alternative to corn in producing ethanol, are now shown to have another beneficial characteristic–the ability to reduce ...

Researcher: Smaller 'dead zone' recorded in Gulf

A new report says this year's Gulf of Mexico "dead zone," an area of low oxygen that develops every spring and summer, is the fourth-smallest since measurements of the zones began in 1985.

NOAA: Gulf of Mexico 'dead zone' predictions feature uncertainty

A team of NOAA-supported scientists is predicting that this year's Gulf of Mexico hypoxic zone could range from a low of approximately 1,197 square miles to as much as 6,213 square miles. The wide range is the result of using ...

Forecast predicts biggest Gulf dead zone ever

Scientists predict this year's "dead zone" of low-oxygen water in the northern Gulf of Mexico will be the largest in history - about the size of Lake Erie - because of more runoff from the flooded Mississippi River valley.

Growing hypoxic zones reduce habitat for billfish and tuna

Billfish and tuna, important commercial and recreational fish species, may be more vulnerable to fishing pressure because of shrinking habitat, according to a new study published by scientists from NOAA, The Billfish Foundation, ...

Researchers predict large 2009 Gulf of Mexico 'dead zone'

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 ...
