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.
