So who wants to talk about this thang, anyway?

The Obama administration is actively trying to dismiss media reports that vast plumes of oil lurk beneath the surface of the Gulf of Mexico, unmeasured and uncharted.

But the National Oceanic and Atmospheric Administration, whose job it is to assess and track the damage being caused by the BP oil spill that began four weeks ago, is only monitoring what's visible -- the slick on the Gulf's surface -- and currently does not have a single research vessel taking measurements below.
