2. What is an Oil Spill?
Release of liquid petroleum
hydrocarbon
 Due to human activity
Form of pollution
Refers to marine oil spill

3. Oil Spill Facts
Takes months or years to
clean up
14,000 spills occur each
year
Consume 400 million
gallons of oil everyday
Deepwater Horizon
killed 33% of fish in the
area

4. What affects do Oil Spills have on Animals?
Seabirds
• Strongly affected
• Ways to die from Oil
Spill
– Feathers are covered with
oil
– Hard to fly and escape
predators
– Cleaning themselves
– Blinding them
•Most die unless humans intervene

5. Continued
Killer Whales
 Ways to die from Oil Spills


Eat fish that swam in oil
Plug the blowhole with oil and drown
• Becoming endangered
Sea Otters
• Fur gets covered in oil which
disrupts air bubbles
-Air bubbles for warmth
-Air bubbles to float
• Die from cold waters
• Placed in captivity for
support

6. Marine Mammals
Whales and dolphins can
come up to breath in oil
slicks
Can cause respiratory
problems or suffocation
Dolphins have been
known to follow clean up
ships into slicks

7. Effects on Wildlife

8. Decrease water quality
Low dissolved oxygen (DO2) levels have been
detected in contaminated areas
DO2 depression have been observed more than 80
km from the well head
DO2 depression likely due to increased biochemical
oxygen demand to metabolize oil hydrocarbons
DO2 levels have not approached hypoxic levels
DO2 depression does not seem to be worsening due
to mixing of high and low DO2 waters

9. Deepwater Horizon Oil Spill
 Cause
Wellhead blowout
 April 20, 2010
 Killed 11 workers
 205.8 million gallons
 Flowed for 3 months
 BP was responsible for the spill
 Largest marine oil spill in history
 In the Gulf Region
 Affected Texas, Florida, Louisiana, and
Mississippi beaches


10. Methods Of Cleaning
 High or low pressure hoses to
Booms
spray oil off beaches
 Sorbents
 Large sponges that collect oil
 Booms
 Collects oil off the water
 Controlled Burning
 Reduces amount of oil
 Skimmers
 Boats that removes the oil
Controlled Burning

11. Dispersant Use
Breaks up oil before it reaches the beaches and
marshes on land
1.8 million gallons were used on the surface and at
source of oil leakage – more than has ever been used
by the US before
Dispersing the oil causes many marine animals to be
subject to oil that would not have been without using
dispersants, which have unknown effects

12. How Dispersant Works
o Sprayed on surface of water, breaks oil down into
tiny suspended droplets, over time broken down by
oil-eating bacteria, sunlight, and wave action and
dispersed throughout the ocean or sinks to the
bottom
o Toxic to marine animals that live/spawn/reproduce
there, trades one ecosystem for another

14. Ways of Preventing Oil Spills
 Navigation
Coast Guard must know
where the tankers can drive
 Inspect equipment more
 Double Hulling
 2 layers of watertight hull
surface
 Prevent/reduces oil spills
 Careful as possible when
transporting

Double Hull
