Stephenie Lai 8101905590 Dec. 4, 2008 MARS 1010L Pahlas Chemosynthesis/Hydrothermal Vent/Cold Seep Communities Synthesis During this week’s lab, we learned about chemosynthesis, hydrothermal vents, and cold seep communities. Deep sea vent communities were explored by a vessel named Alvin. The vessel is owned and operated by the Woods Hole Oceanographic Institution (WHOI). It is named after a WHOI engineer. Alvin is able to hold one pilot and two passengers. Its maximum depth is 14,764 feet. This is possible due to Alvin’s ability to resist the crushing pressure of deep water. Alvin can be submerged for up to ten hours although it can provide life support for up to 72 hours. This unique vessel makes deep sea research possible. Chemosynthesis, unlike photosynthesis, uses inorganic molecules or methane as a source of energy rather than sunlight. It converts carbon molecules and nutrients into organic material. CH2O and H2SO4 are the by-products of chemosynthesis. This process occurs at hydrothermal vent sites because there is a reduced amount of chemicals to
