How much oil was spilled in Exxon Valdez?

The current estimate is between 114 million and 144 million liters (about 800,000 barrels). This number is far beyond the hopelessly optimistic number put forth by Exxon, who gave a "low-ball" estimate of about 10.8 gallons. This number, unfortunately, is still reported in the press but two independent investigations have found the estimate erroneous in the extreme.
