organisms would then be able to break down the organic pollutant at a correspondingly faster rate. In fact, bioremediation is often used to help clean up oil spills. Bioremediation of a contaminated site typically works in one of two ways. In the case described above, ways are found to enhance the growth of whatever pollution-eating microbes might already be living at the contaminated site. In the second, specialized microbes are added to degrade the contaminants. Bioremediation provides a good

INTRODUCTION • Each major oil spill → ecological impact assessment (EIA) • Studies may differ (targets, methods, duration…) from one accident to another: - Pollution features (e.g. meteo oceanic conditions…); - Ecological concerns (sensitivity, special interest…); - Type of oil (crude vs. fuel); - Research team availability;

CHAPTER ONE INTRODUCTION 1.1 BACKGROUND TO THE STUDY Oil spill is the leakage or discharge of petroleum onto the surface of inland or coastal water. It assumes disastrous dimension when an uncontrollable well blows out or pipeline ruptures. On water surface, spreading takes place immediately, which is very harmful to various types of aquatic lives as it prevents sufficient amount of sunlight from penetrating and also reduces the land-dissolving capacity in the water. The magnitude of crude

Summary of Valdez On March 23rd, 1989 a ship called the Exxon Valdez was leaving from Alaska on the way to California. The Valdez was hauling over 53 million gallons of crude oil at the approximately 9:12 PM, the time of departure from the port. The Valdez was piloted by Captain Joseph Hazelwood and Marine Pilot William Murphy. Accompanying the pilots were 19 crew members to assist with the haul. The ship was originally scheduled to depart at 10:00 PM, however, the departure time was changed without
