Alvin is a tool used by marine biologists to explore the unknown deep waters of the sea. This tool captures the life of creatures that live in unbearable living conditions such as extreme water pressure, little sunlight, and toxic chemicals. Alvin is used to conduct research and is owned by the United States Navy.


In the movie, Alvin was able to enter the hydrothermal vents of the Mid Ocean Ridge. The Mid Ocean Ridge is where the Earth’s crust was built. IT is located in the center of the Atlantic and Indian Ocean where there is Volcanic activity. Chemicals are found here. Especially the dangerously toxic chemical of H2S Hydrogen Sulfide.
Alvin is made by rubber bands held together tightly. This is adaptable to anything a marine divers desires to do in the deep waters. Alvin can go13,000 feet below sea level. The pressure of Alvin is enough to crush a tank, but it can sustain! Go ALVIN!
Descends 9 North. Remember, Alvin can go into places that are less accessible than places that can enter the moon. Alvin sees the seas that no person may have ever seen before.

Deep Sea Hydrothermal vents:
Deals with volcanic rock deep within the earths crust. The geysers in Yellowstone national park is an example of how these works in the seafloor.  They are filled with mineral-rich chemicals that hold a community of organisms that can live in these particular environments. Temperatures can reach as high as 750 degrees in the waters.






Holger Jannasch:
He says that, “Science is an adventure, not a career” (Jannasch).
He has made 23 Alvin dives where he desired to study deep sea bacteria.  He found that the high pressures and very cold temperatures slow bacteria metabolism by 100 times. 

 At first he was not able to bring up bacteria to the surface before they decomposed when reaching the top,but eventually he and his team was able to preserve their purity and study them in lavatory above their natural environment.



Sea dandelion:
 Looks like one organism but it is really just a cluster or organisms bundled up together.  This organisms is found in the deep seas in the hydrothermal vents. They can survive off some of the most toxic chemicals in the sea.


Chemosynthesis:

Instead of photosynthesis, the deep sea creatures receive their energy through chemicals and no sunlight. The organism found in the hydrothermal vents have this characteristic.
