Shall we do a sum?Studies using a submersible found a layer, as much as 10cm thick in places, of dead animals and oil, said Samantha Joye of the University of Georgia.

If the layer is 70% animal to 30% oil,

and all the oil from the well is still there, none of it dispersed, in a 10cm thick layer,

then the layer would cover a section of the Gulf measuring 5km by 4km.

The Gulf is rather bigger than that.

Samantha Joye of the University of Georgia is using scare tactics and not giving an unbiased view of reality. In reality, the more of it that's in a 10cm layer the better. Even so, even if it were nastily thinned out instead of conveniently confined to a 5km by 4km oval, it's still a minimal part of the Gulf that even knew there was a problem to start with.
