What type of oil was spilled in Exxon Valdez?

The Exxon Valdez oil spill involved crude oil, specifically a type known as North Slope crude oil. This oil is a light, sweet crude, characterized by its relatively low density and low sulfur content. The spill occurred on March 24, 1989, when the Exxon Valdez tanker struck a reef in Prince William Sound, Alaska, releasing approximately 11 million gallons of oil into the pristine marine environment.
