Now for a little exercise in News Spin Cycles, vs the Scientific Process …

When the Facts, finally come in, IS Anyone even still Paying Attention?

“What we have learned completely changes the idea of what an oil spill is,” said chemical oceanographer David Hollander, one of three USF researchers credited with the matching samples of oil taken from the water with samples from the BP well. “It has gone from a two-dimensional disaster to a three-dimensional catastrophe.”

Together, the two studies confirm what in the early days of the spill was denied by BP and viewed skeptically by NOAA’s chief – that much of the crude that gushed from the Deepwater Horizon well stayed beneath the surface of the water.

Cool, being a life-long Science fan, I have always liked Experiments …

But I generally prefer those of the ‘Controlled Experiment’ variety.  Those fly-by-night Variety, like combining a jet of Hair Spray with a tiny Lighter flame, always left me a little frightened.

Funny, I’m starting to feel that way again …

As the oil gushes from the broken well head at the sea floor, Rader says it has the potential to contaminate each layer of the water column that, “directly exposes those animals to toxicity, at the surface including the very sensitive surface zones where not only sea turtles and marine mammals and sea birds can be oiled, but also where the highways for fish larvae exist. And then as it rains back into the abyss over a much wider area carrying toxicants back into the deep sea where ancient corals and other sensitive ecosystems exist.”

One response strategy has been to use dispersants or anti-freeze-like chemicals to break the oil up into smaller globules.

It is a choice, he says, between two bad options. While the chemicals may protect birds and other wildlife by dissipating the slick before it reaches shore, their toxicity in the Gulf could harm fish and other marine life.
