"Activities and productivity of the Sub-Seafloor Biosphere at Deep-Sea Hydrothermal Vents"
Dr. Stefan Sievert
Associate Scientist
Woods Hole Oceanographic Institute

12:30 pm to 1:30 pm
SMAST East, Rooms 101/102
836 S. Rodney French Blvd, New Bedford
Abstract:
Despite 40 years of research, knowledge of in situ metabolism of microbes carrying out carbon fixation in marine hydrothermal systems is still very limited. Particularly lacking are studies identifying the chemosynthetically active microbes and measuring rates of CO2 fixation in situ. Here, I present data from innovative incubations that maintained seafloor pressure and temperature for assessing chemoautotrophic production in deep-sea vent systems. Overall, our data provide a comprehensive view of the sub-seafloor biosphere underlying the studied vent site and its biogeochemical significance for the surrounding deep ocean.
