(Newser) – The Gulf of Mexico is seeing one of the biggest low-oxygen areas—or "dead zones"—on record this year. A dead zone forms in the Gulf around this time every year, but the 2010 incarnation is 7,722 square miles, just a few hundred short of the record size of 8,000, the AP reports. Marine scientists aren't sure if the development has anything to do with the Gulf oil spill.
