| contents | Ocean Drilling Program Leg 167 drilled thirteen sites in a series of depth and latitudinal transects along the climatically sensitive California margin to reconstruct the Neogene history of deep-, intermediate-, and surface-ocean circulation changes (Lyle, Koizumi, Richter, et al., 1997, doi:10.2973/odp.proc.ir.167.1997). Significant variations occurred in sediment properties on all time scales as seen in the high-resolution nondestructive shipboard measurements (e.g., bulk density and color reflectance), high- to intermediate-resolution downhole log measurements (e.g., resistivity and magnetic susceptibility), and lower resolution discrete shipboard measurements (e.g., physical properties and carbon geochemistry). Thus, these Leg 167 sites provide an opportunity to address paleoceanographic questions about the evolution of the California Current and links between the equatorial Pacific and the high-latitude North Pacific from millennial and orbital to tectonic time scales. This data report presents the results of biogenic opal analyses from a latitudinal transect of seven sites along the California margin for the time interval from 8 Ma to the present. Site selection for opal analyses was based upon such parameters as opal content, stratigraphic continuity, and lack of coring disturbance. |
