Deep Sea Deep Secrets

This movie followed Holger Jannasch and the Woods Hole Marine Biology Laboratory and their research with deep sea hydro-thermal vents. To learn more about Jannasch and the laboratory, check out this link: http://www.whoi.edu/page.do?pid=10934&tid=3622&cid=817

Organisms

There are several kinds of organisms found in the deep sea hydrothermal vents. 

• Octopods are the top predator of the feeding web. They are also the most intelligent.

• Spaghetti worms can grow up to 8 feet long, and they drape around rocks.

Alvin

Alvin is a submarine-like machine with a pressurized cabin that holds three people. Alvin is able to operate at 13,000 feet below sea level. Scientists use Alvin to travel to the deep sea hydro-thermal vents around 9,000 feet below sea level. It takes about 2 hours for Alvin to reach the destination. Once there, Alvin is able to take pictures and collect samples of plants and animals.

Solar Trajectory Diagram

     For my solar trajectory project I found a wooden post that measured 3ft. 31/2in. tall.  I stuck the post in the ground in a field behind my building that allowed the sun to cast a shadow without being blocked by any trees or other objects.  On March 6th, I measured the shadows cast by the sun at three different times: 8:00 A.M., 10:45 A.M., and 5:00 P.M.  Also at each of these times, I used a compass to measure the direction that the sun was shining.  I then used special graphing paper to plot my measured points and measure the solar trajectory for that day.  After taking a closer look, my professor and I realized that the graphing paper I used had been printed wrong and was actually a mirror image of what it should be. I have included a picture of my trajectory below.

Topographical Map

      I created a topographical map of Mount Fuji, which is located on Honshu Island in Japan.  It is the highest mountain in Japan.  I created lines surrounding the mountain at 7,000, 9,000, and 10,000 feet.
