BP Deep Water Horizon Well
Five Years Later
April 20, 2015, Methane gas blew out from a
wellhead a mile below the Gulf of Mexico.
At a Pressure 150 times greater than air at
the Earth’s surface, the gas shot up
through a drilling riser to the Deepwater
Horizon oil platform and platform and
exploded, killing 11 workers.
2 Days later the burning rig sank,
It was the worst offshore oil spill in history. It
continued to gush oil for 87 days, spilling
200 million gallons of crude spilling crude
oil in a four-dimension disaster that
reached from the Gulf’s floor to the its
surface, and its seashore.
What happened to the Oil?
Some of it was burned off, some of it was skimmed
up and also applied chemical dispersants used
to break up some of it so that it would either
dissipate, become soluble or be small enough
for microbes to eat.
But 5 years later, up to 10 percent remains in
marshes and anywhere from 3 to 30 percent –
though 10 percent is probably a good estimate –
is on the ocean floor.
BP is drilling two relief wells, which will permanently intersect with
the damaged well and shut down the flow of oil into the Gulf
of Mexico by pumping concrete into it.

Gar Fish Dissection
Gar bodies are elongated, heavily armored
with ganoid scales, and fronted by similarly
elongated jaws filled with long, sharp teeth.
Their tails are heterocercal, and the dorsal fins are
close to the tail.
As their vascularised swim bladders can function
as lungs, most gars surface periodically to take a
gulp of air, doing so more frequently in stagnant or
warm water when the concentration of oxygen in
the water is low.
They also appear to surface in fast-moving rapids.
As a result, they are extremely hardy and able to
tolerate conditions that would kill most other fish.
