The deep
sea has been described as “The final frontier” because there are still
incredible mysteries that we do not know about this unique ecosystem, even with
the advanced technology today. The largest of all these deep-sea ecosystems is
the Mariana trench reaching an amazing 7 miles in depth. The Mariana trench is
also 50 times larger than the Grand Canyon. I was always under the impression
that it was just a tunnel that went down extremely deep, in the shape of an
underwater volcano. The deep sea and the incredibly unique creatures that
inhabit it have always fascinated me. Ever since I was a little kid I have
always wanted to dive to extreme depths of the ocean and discover some rare
type of fish that was never previously known about. Therefore, James Cameron’s
dive down to the Mariana trench was of great interest and I decided to look
into it more and see what his findings were.
James
Cameron is the first human to go down to these depths since 1960 when the first
expedition was sent down to the deep. Since then, 5 people have died trying to
make it to the bottom of the ocean floor. This article
states that the submarine alone that Cameron went down in took 7 years to
build. Due to the immense amount of pressure exerted at these depths a state of
the art vehicle had to be built. A project of this magnitude is obviously
extremely expensive. This dive was funded by National Geographic, Richard
Branson (owner of Virgin Records/Mobile), and Eric Schmidt (CEO of Google).
Unfortunately, Cameron says that he did not see much at the bottom of the ocean
on his epic dive. I thought that he was going to find some unique creatures
that have never been seen before. Cameron states that it was just bleak and
resembled the moon. The trip was supposed to last for 6 hours, however, the
submarine experienced an oil leak after only 3 hours due to the enormous
amounts of pressure. Cameron had to ascend up in a hurry, completing the 7-mile
accent in only 70 minutes. Just to put into perspective how much pressure is
down at that depth, the article said that it is equivalent to three full size
SUVs on your thumb, on every inch of your body. At these depths the pressure is
about 16,000 pounds per square inch. The pressure was so great that while the
submarine was at the bottom it actually shrunk an entire three inches. As a
side note, once more of these submarines are developed people will be able to
pay to take a trip down to the bottom of the Mariana trench. Price tag? 250,000
dollars per person.
Not only is
it important to explore the deep seas to discover the unique creatures that
inhabit that ecosystem, but scientists also believe that that deep-sea trenches
play an essential role on earthquakes, such as the recent devastating
earthquake in Japan due to the push and pulling of tectonic plates. This brings
up an interesting debate that sparked my interest. Public policy officials have
been debating if the funding of these types of expeditions and organizations
should be funded by public tax dollars or wealthy private individuals (like in
this example). I have mixed emotions. I understand this type of research is absolutely
important, however, I am sure there was a hefty price tag on the funding of
this research, which that money could have been allocated to something closer
to home such as education. What do you think about the funding of a project
like this by public tax dollars?
A great deal of basic research funding leads to economic benefits that are hard to predict or plan ahead. So while deep sea exploration may seem expensive, who knows what new energy source, drug of other technology will come from the science that is done there.
ReplyDeleteThat is true, I never though about it that way. With the vastness of the deep sea it is very possible that we could find some new energy source or some sort of drug. I would love to do research on a compound/drug isolated from the deep sea and its affects on the human body!
