Predictably, some Louisiana lawmakers (is that really a good way to describe these folks?) are rushing to defend the now-defunct Taylor Energy company which, according to ex-Senator Mary Landrieu, should be “commended for its diligent, collaborative, and environmentally responsible work on this matter.”

“This matter” is a chronic leak that’s been pouring crude oil continuously into the Gulf for almost 11 years, and shows no signs of tapering off.  Taylor Energy has declared — apparently with no explanation or corroboration by independent experts — there is nothing they can do, that wouldn’t cause worse harm to the environment.  Federal officials estimate the leak will continue for another 100 years, until the reservoir is tapped out.

Here’s a satellite image of the Taylor site just a few miles off the coast of the Mississippi Delta, showing a 21-mile-long slick extending northeast from the location of the buried, leaking wells.   It was shot from NASA’s EO-1 satellite on July 3, using the Advanced Land Imager (ALI) instrument.  It has some remarkable detail: a thin sheen, slightly darker than the adjacent Gulf waters, surrounding a thin pale-blue streak that indicates oil thick enough to have the distinct reflectance signature characteristic of crude oil. We estimate the sheen is, on average, 1 micron (one millionth of a meter) thick.  The pale-blue core is much thicker, perhaps millimeters thick. This is consistent with direct observations and sampling of the Taylor slick conducted by researchers from Florida State University last summer.

Using our conservative rule of thumb — that a slick observable on satellite imagery is, on average, at least one micron thick — we calculate the 21-mile-long Taylor slick on July 3 represents at least 8,100 gallons of crude oil. And what did Taylor Energy report to the Coast Guard that same day? A slick 12 miles long containing 71 gallons.

Commendable indeed.
