Exxon Valdez Oil Spill

• Ocurred in Prince William Sound , Alaska in March 24, 1989 .

• Is one of the biggest environmental tragedies in history. This ship spilled

a minimum of 10.8 million gallons.• It cover 1,300 miles (2,100 km)at coastline and 11.000 square miles of ocean

(28,000 km).

Environmental Consequences

It destroyed the microbial populations on the shoreline; many of these organisms are the basis of the coastal marine food chain, and others are certain bacteria and fungi , they make easy the biodegradation of oil.

Thousands of animals died immediately; the best estimates include 100,000 to as many as 250,000 seabirds, at least 2,800 sea otters, approximately 12 river otters, 300 harbor seals, 247 bald eagles, and 22 orcas, as well as the destruction of billions of salmon and herring eggs.

Oil Spill At Gulf of Mexico

Occurs when some combination of pressurized natural gas, oil, mud, and water escapes from a well, shoots up the drill pipe to the surface, expands and ignites.

• The catastrophic explosion that caused an oil spill from a BP offshore drilling rig in the Gulf of Mexico has reached the shoreline .This is on track to become the worst spill in history, surpassing the damage done by the Exxon Valdez taker. This Oil Spill was at the state of Louisiana at 48 miles out in the Gulf of Mexico from the mouth of the Mississippi.

Oil Spill

• The official estimations of which 5,000 barrels (795,000 liters) would have spilled in the Gulf every day since the platform of perforation of Deepwater Horizon exploded weeks ago

• Oil Spill Response Louisiana has begun spending money on oil spill

response, installing containment booms around some areas. which had collected 48,000 gallons of oil-water

• How big is the oil spill and how fast is it growing?

• The oil spill has grown in size since the initial accident as the oil spreads across the surface of the ocean.

• The lighter the oil is, the faster it can spread • the oil spill has a circunference of about 600

miles (about 970 kilometers)• The spill is big enough to be seen from space.
