    . . . It's been eight years since baby oysters started dying by the billions at an Oregon hatchery and in Washington's Willapa Bay.

    In 2009, top scientists drew global attention when they said evidence suggested the culprit might be changing ocean chemistry from the same greenhouse gases that contribute to global warming. They just couldn't prove it — until now.

    Researchers said Wednesday they can definitively show that ocean acidification is at least partly responsible for massive oyster die-offs at the hatchery in Netarts Bay, Ore.

    It's the first concrete finding in North America that carbon dioxide being taken up by the oceans already is helping kill marine species.

    First they are going to have to explain how the wind blowing above the surface of the ocean brings up waters from the ocean so deep that light does not even penetrate.

    Sounds like they are reaching to get to their conclusion.

    I am not surprised. Most oyster beds are less than 10 feet under the water. A good chop can stir mud up in oyster beds.
