A continuous splice could be constructed from 0-190.85 mcd, the interval of APC coring. Incomplete core recovery and decreased core quality precluded splice construction below this interval. The green clay layers are less frequent in Subunit IB, and turbidite layers are more frequent. Calcareous nannofossils are abundant and well preserved above the Pliocene, though preservation deteriorates through the Miocene. Planktonic foraminifer are abundant and have good preservation for the entire interval at this site.
Benthic foraminifer are generally very rare but become more abundant in two short intervals.
Further shipboard interpretation of paleomagnetic measurements were not possible because of pervasive drill string overprint. A preliminary calculation shows that the remarkable decrease in sedimentation rate from the late Miocene to Pleistocene is caused by declining accumulation rates of both carbonate and noncarbonate components. However, the non-carbonate, mainly terrigenous accumulation rates increases again after about 3 Ma, while the carbonate accumulation rates continue to decrease. Other hydrocarbons are below detection limits. This extended interval of sulfate reduction appears commensurate with the low organic carbon and methane content in the sediments.
