Summary: During Ocean Drilling Program (ODP) Leg 185, two sites were sampled in the oldest crust of the western Pacific Ocean. The scientific objectives were twofold: (1) to characterize the nature of the oldest in situ oceanic crust on Earth in terms of its formation and subsequent sedimentation and alteration and (2) to determine the bulk geochemical characteristics of crust being subducted into the Izu-Bonin and Mariana trenches, as part of a larger global experiment aimed at understanding geochemical budgets at subduction zones. This synthesis summarizes results presented in more than 35 papers published not only in this Leg 185 Scientific Results volume but also in several journal articles and, specifically, in a special thematic series of articles on Oceanic Inputs to the Subduction Factory published in Geochemistry, Geophysics, and Geosystems (G3). Leg 185 science also supported the theses of 12 students in universities around the world.
