Re: Permian extinction

too, into the atmosphere.>

  If the bolide of any extinction event were to hit the ocean,
regardless of where in an ocean, it would have been worse than if the
bolide hit dry land. Water evaporates, and you have about 10% of the
earth's water _gone_. In the air. Climate change. Not to mention
pollution and destruction of everything in the water, except for maybe
algae and bacteria. Or perhaps a few other things.

  The deeper the water, the worse. The shallower, as wierd as it may
sound, the better, for the water is more or less untouched directly.
And that's better for all things considered.
