doi:10.2204/iodp.sp.329.2010 Relationship to previous drillingProposed Site SPG-1A is located in the western portion of the gyre, near DSDP Sites 595 and 596 (Menard, Natland, Jordan, Orcutt, et al., 1987). There are no DSDP/ODP/IODP sites near any of the other proposed sites. The closest sites were cored during Leg 92, which recovered Oligocene and younger sediment from a series of sites at 20°S (Leinen, Rea, et al., 1986). The Leg 92 sites are located beneath higher productivity waters than the central gyre (Fig. F1). The entire sediment column was cored at the Leg 92 sites; basement was encountered between 1 and 50 mbsf (with sediment depth increasing westward). | |
