Amoco Cadiz oil spill

environmental disaster, off the coast of Brittany, France [1978]

Quick Summary

The Amoco Cadiz oil spill was a major environmental disaster that occurred off the coast of Brittany, France, in 1978. The supertanker, carrying nearly 69 million gallons of crude oil, ran aground due to a damaged rudder and hydraulic system in rough seas. Despite attempts to tow the ship, it broke apart on underwater rocks, releasing its entire cargo.12

This spill contaminated approximately 200 miles of the French coastline, resulting in the deaths of millions of invertebrates and an estimated 20,000 birds. Oyster beds were also contaminated. The Amoco Cadiz disaster led to significant changes in shipping regulations and emergency response organization for ecological events. It remains one of the largest oil tanker spills in history.21
