Expedition 329: South Pacific Gyre Microbiology

 October 9th, 2010 - December 13th, 2010

Location: leaving from Papeete, Tahiti, ending in Auckland, New Zealand

Co-chief Scientists: Steven D'Hondt (University of Rhode Island) & Fumio Inagaki (Japan Agency for Marine-Earth Science)
Staff Scientist: Carlos Alvarez Zarikian
Logging Staff Scientist: Helen Evans

Education Officer: Joe Monaco

In October 2010, an international team of scientists set sail on the scientific drilling vessel JOIDES Resolution for an eight- week expedition to the South Pacific. There, we will penetrate a total of 630 m at seven different drill sites to define the physical and chemical limits of subseafloor microbial life in tectonic and oceanographic settings not yet explored!

We will (1) document habitats, activities, composition, and biomass of microbial communities in subseafloor sediment with very low total activity and very low biomass, (2) determine oceanographic controls on sedimentary habitats, activities, and communities from gyre center to margin, (3) constrain the extent that the subseafloor communities are nourished by hydrogen produced in situ by water radiolysis, and (4) determine how basement habitats, potential activities, and communities vary with crustal age and hydrologic regime and evolve over 100 million years in a region of fast seafloor spreading and very low sedimentation rate.
