Forecast Seamount Hydrothermal Vents from Voyages of Discovery: NOAA's Okeanos Explorer on explo.tv

Forecast Seamount Hydrothermal Vents (Clip)

Date: May 1, 2006

Running Time: 00:01:01

The remotely operated vehicle (ROV) Jason II measured temperatures as high as 200 degrees Celsius (392 degrees Fahrenheit) at these hydrothermal vents atop the Forecast Seamount in the Mariana Arc of the Pacific Ocean. Hydrothermal vents spew sulfur and other chemicals that support bacteria which use these chemicals to sustain life in a process called chemosynthesis. Snails and shrimp have colonized the site and are grazing on the chemosynthetic bacteria. Jason's suction sampler is used to collect some of these animals for analysis in the lab on board the ship.
