Dark Ecosystems Nurtured by Oil (NYT)

"How much oil seeps up from the seabed, aside from oil spills? Quite a lot, and a fascinating group of sea creatures thrives on it," writes William Broad in the New York Times Green Blog about sea creatures that thrive on natural oil seeps in the deep, dark ocean: Dark Ecosystems Nurtured by Oil.

"In 2003, the National Research Council released a comprehensive study, 'Oil in the Sea III: Inputs, Fates and Effects.' The 265-page report paints a global portrait of the petrochemical flows, both natural and unnatural. It turns out that the largest contributors [of petrochemicals in the ocean] far and away are the natural seeps, like those across the bottom of the gulf that power the dark ecosystems."

Of course, as one commentator pointed out, the BP Deepwater Horizon spill has leaked "an amount equal to 75 percent of the annual natural seepage worldwide, except it has occurred in 2 months in one specific location."

BP: Latest Effort Captures 1,000 Barrels of Leaking Oil Per Day

According to a report in yesterday's Environmental Leader, BP successfully connected a mile-long tube into a broken pipe at the Deepwater Horizon well to start capturing some of the leaking oil, which is being siphoned to a ship at the surface.

BP said it is capturing about 1,000 barrels per day in the Gulf of Mexico, a drop in the bucket compared to the 5,000 barrels (210,000 gallons/795,000 liters) it estimates to be leaking daily.

The question is, do those estimates underestimate the amount of oil gushing from the sea floor?

Some scientists believe that oil is gushing out at a rate of somewhere between 25,000 to 80,000 barrels a day. The New York Times reported over the weekend that huge plumes of oil -- some 10 miles long, 3 miles wide and 300 feet thick -- have been found underwater in the Gulf.

BP has resisted efforts to determine the size of the leak, preferring to focus on containment efforts. They hope to have the leak stopped by the end of the week.
