Exxon Valdez Oil Spill


Ocurred in Prince William Sound , Alaska in
M
arch 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.

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.


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.
