Oil Gobbling Microbes Not Causing "Dead Zones"

WASHINGTON (AP) - A new federal report says microbes that are
gobbling up oil from the BP spill haven't caused problems with
oxygen loss in the Gulf of Mexico.
Federal officials say some underwater oxygen levels have fallen
by 20 percent, but the levels aren't low enough to create 'dead
zones.' They say that's good news because it shows the microbes are
working, but aren't causing oxygen loss.
Steve Murawski (MOO-row-ski), the scientist who headed the
federal research team, said that means efforts to control the oil
with dispersants hit the "sweet spot" they were aiming for.
Scientists worried that if microbes had eaten too much, it would
deplete the oxygen in deep water, choking fish. But more than 400
tests show that the oxygen levels weren't dangerously low.
