Radiolarians and diatoms are essentially absent, except for reworked Miocene taxa. The Holocene is well marked by interglacial planktonic foraminifer assemblages. Planktonic and benthic foraminifer assemblages suggests that the glacial-interglacial episodes are associated with changes in circulation of upper intermediate waters affecting changes in oxygen levels of the basins of the California Borderland. Gas voids, turbidites, and coring disturbances precluded the measurement of most physical properties and the determination of a paleomagnetic reversal stratigraphy. Furthermore, the sequence is too young to contain magnetic field reversals.
Lowest values occur in the turbiditic sequences.
Methane concentrations are high throughout the sediment column, however, no significant amounts of ethane were observed.
