SkyTruth is reporting that their analysis of radar satellite images and "conservative calculations" indicate that in the first week of the oil spill at least 6 million gallons may have entered the Gulf. That's a spill rate of at least 850,000 gallons (20,000 barrels) per day, 20 times larger than the official Goast Guard estimate of 42,000 gallons per day.
The Australia blowout and spill took 10 weeks to control.
The Exxon Valdez tanker spill totaled 11 million gallons.
Do the math and you'll see that this spill has the potential to blow by the Exxon Valdez amount.
