航海の目的

Based on IODP Proposal 662-Full3, this expedition is intended to define the physical and chemical limits of subseafloor microbial life in tectonic and oceanographic settings not yet explored. Science objectives include

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

Coring will target sediment and oceanic crust.
