It sounds like the question they have to answer is, how much DDT does it take to poison all the seas on the planet?

Since it has remained more or less concentrated in certain areas, I'm wondering if it is by nature more dense than seawater. That it hasn't dissipated into the surrounding seawater in all this time seems to suggest that when left undisturbed it doesn't mix easily with water, either. That could make cleanup somewhat easier, but vacuuming anything off the sea floor 3000 feet down isn't going to be a walk in the park regardless.
