Here are some of the worst oil spills in history:

10. The Odyssey: 132,000 tons

In November 1988, the American-owned oil tanker Odyssey split in two 700 miles off the coast of Nova Scotia. The tanker spewed about 132,000 tons of crude oil into the sea and caught fire as it sank, setting the spill aflame. Because of hazardous weather conditions, the Canadian Coast Guard could not immediately reach the spill, and much of the oil burned.

9. The Haven: 145,000 tons

A violent explosion aboard the Cyprus-based tanker the Haven killed six members of the crew and spilled 145,000 tons of oil off the coast of Italy in April 1991. About 70 percent of the oil burned in the ensuing fire. In most oil spills, oil remains near the surface of the water, but in this spill some of it sank. Oil from the Haven was later found in ocean beds at depths of up to 1,640 feet (500 meters).

8. The Amoco Cadiz: 223,000 tons

Stormy weather drove the Amoco Cadiz Very Large Crude Carrier (VLCC) aground on the Portsall Rocks, a 90-foot deep outcrop off the coast of Brittany, France, in 1978. The ship split in two and quickly sank before its 1,604,500 barrels of oil load could be pumped from the wreck.

7. Castillo de Bellver: 252,000 tons


6. ABT Summer: 260,000 tons


5. Nowruz oil field: 260,000 tons

During the first Gulf War, a tanker collided with a platform on Feb. 10, 1983, spilling approximately 1,500 barrels each day, until the platform was attacked by Iraqi planes in March and the slick caught fire. The Nowruz oil field was not immediately capped, because the field was located in the middle of the Iran/Iraq war zone. The well was finally capped by Iran in September of that year – an effort that resulted in the deaths of 11 people.

4. Fergana Valley: 285,000 tons

The Fergana Valley, one of Central Asia's most densely populated agricultural and industrial areas, was the site of the largest inland oil spills in history in 1992.

3. Atlantic Empress/Aegean Captain: 287,000 tons


2. Ixtoc I oil well: 454,000 tons


1. Gulf War oil spill: 1,360,000 -1,500,000 tons
