Gulf ‘dead zone’ suffocates fish, livelihoods
GULF OF MEXICO (CNN) — Fisherman Terry Pizani turns his captain’s wheel with a mournful expression on his face. Far below, the fishing grounds off the Louisiana coast where the 63-year-old has made a living for five decades have become an aquatic graveyard known as a "dead zone."

Fisherman Terry Pizani’s shrimp catch is not as plentiful because of the Gulf of Mexico’s “dead zone.”

CNN traveled aboard the ship August 14-15 as consortium researchers sent sensors to the bottom of the sea, scooped up sediment and collected water samples for analysis at nine testing stations in the Gulf.
As an oxygen meter sank far below the Pelican, Pride pointed to an onboard computer screen displaying the meter’s findings in real time.
"This green line is the oxygen right here and at the bottom it’s reading less than 2 milligrams per liter," Pride said.

Six of the nine stations revealed such oxygen-deprived, hypoxic water, compared to a normal reading of 6 milligrams per liter.
As Pride and her crew aboard the Pelican monitored the Gulf waters, the journal Science last week published a study that reveals there are more than 400 dead zones around the globe, double the number found by the United Nations two years ago.
One of the major dead zones is in the Gulf of Mexico. It is 8,000 square miles, nearly the size of New Jersey, according to the marine consortium’s annual measurement completed in July.
"There’s no oxygen in the water for shrimp, crabs, fish to live," said Nancy Rabalais, executive director of the consortium.
