Frequency may signal early dead zone in bay - al.com: "If the frequency of Mobile Bay's famous jubilees are any indicator, the rivers that feed into the Mobile-Tensaw Delta are likely carrying one of the heaviest loads of fertilizers and other nutrients on record this year.

That's a bad thing in terms of the health of Mobile Bay, because a jubliee is more than just a seafood bonanza. Scientists say they prove that the bay has the same kind of low-oxygen dead zone that has plagued the Gulf of Mexico in recent decades.

This isn't the first time the bay has had a dead zone, according to biologists; one sets up every year in deeper water south of the Middle Bay Lighthouse, typically in July and August."
