THE GULF WAR OIL SPILL TWELVE YEARS LATER: CONSEQUENCES OF ECO-TERRORISM

ABSTRACT The intentional release of an estimated 11 million barrels of oil during the 1991 Gulf War was the largest oil spill in history. An assessment of the physical, chemical, and ecological impacts of this spill shows that, 12 years later, oil residues and habitat modifications continue to have toxic effects on intertidal communities. As of 2003, there are an estimated 8 million cubic meters of oiled sediment remaining along the 803 km of impacted shoreline in Saudi Arabia. Of this volume, 45% occurs in muddy tidal flats and 23% in salt marshes and mangroves. Much of the oil in these sheltered habitats occurs as oiled crab burrows, with liquid oil remaining in the burrows to depths that exceed 50 cm. These habitats show the lowest degree of ecological recovery since the spill, with 87% of the upper intertidal zones of mangroves and marshes and 71 % of muddy tidal flats having reduced species richness and a disturbed community structure. Those habitats exposed to the greatest amount of wave activity co...
