Natural Phenomena
The natural
phenomena I choose to research, was is the preservation of bodies and ships in
Lake Superior due to the cold temperature and lack of animals. In specific for this project I will study the
wreckage of the Edmund Fitzgerald and how through natural processes the bodies
and the boat are still intact.
The
Edmund Fitzgerald was a frater ship, used to take iron ore from Wisconsin to
the Rouge Plant in Dearborn, Michigan.
On the night of November 10, 1975, the Fitzgerald was caught in a
storm. The ship took on too much water,
and with the weight of the water and the weight of the iron ore the ship
sank. The ship sank in Lake
Superior. All 29 members of the crew
went down with the ship and the ship still lay on the bottom of the lake. The
ship sank approximately 17 miles down into the cold waters of the
Superior. Frequent dives were done to
see the ship until the Canadian government put a permanent ban, after multiple
requests from the families of the fallen sailors.
The ship today
serves as a underwater graveyard. On the
dives previous to the ban, the divers said they saw the bodies of the sailors
in impeccable condition for being submerged for that period of time. This is due to the naturally cold waters and
lack of animal life in Lake Superior.
Usually when casualties of shipwrecks are discovered they have reached
the surface due to the heat of the water causing the body to fill with gas and
float up, or onto shore. With the coldness of the lake, the bodies are kept in
a freezer, of 20 degrees Fahrenheit. New
information is showing the due to global warming the temperature of the lakes
seems to be rising, and this summer (summer of 2012) was the warmest
temperature for lake superior, with a temperature of 68 degrees
Fahrenheit. I personally have been
fascinated with the natural phenomena of the preservation of the bodies due to
the coldness since I was a little child, and I heard a story of it through my
times on my lake house on lake Huron. I
originally thought it to be false, though through research, I found it to be
true and a phenomenal.
