Enhanced paleoproductivity across the Oligocene/Miocene boundary
as evidenced by benthic foraminiferal accumulation rates.
Palaeogeography, Palaeoclimatology, Palaeoecology,

The Oligocene to Miocene boundary (23 Ma) marks one of the major
Cenozoic cooling steps. A corresponding but slightly lagging d13C
maximum in benthic foraminifer calcite of globally distributed
sediment cores has been attributed to increased organic matter
burial, either on land or in the oceans. To test this idea we
reconstruct the organic carbon flux to the sea floor at three
Atlantic Ocean Drilling Program (ODP) Sites using benthic
foraminiferal accumulation rates (BFAR) and compare them with
the stable isotope records. Our data show that the d18O and d13C
maximum that characterizes the Oligocene/Miocene boundary is
accompanied by a pronounced maximum in BFAR derived
paleoproductivity at two of the sites. At tropical Atlantic
Site 926 the paleoproductivity increase at the Oligocene/Miocene
boundary is smaller than at the higher latitude sites, but high
resolution sampling of a 2 million year interval (22-24 Ma)
reveals that on eccentricity time scales productivity and stable
isotope records are significantly correlated. The productivity
records are in phase with the d18O and d13C records at the
short-term (~125 ky) component of eccentricity. At the long-term
eccentricity period (~400 ky) productivity is in phase with d18O
but leads the d13C record by an amount that is consistent with
published phase lags between the d18O and d13C records.
These results imply that there was enhanced flux of organic
matter to the ocean floor during the O/M climate transition
and support that marine primary productivity may have played
a role in the carbon cycle and atmospheric CO2 draw-down
at this time.
STUDY NOTES: Atlantic Ocean paleoproductivity data from 3 cores for a 5 million
year interval (20-25Ma) across the Oligocene-Miocene Boundary.
Data include accumulation rates, planktic/benthic foraminifer
ratios, carbonate and organic carbon content, benthic foraminiferal
numbers per unit of time, stable isotopes, and geochemistry,
interpreted in terms of orbital control of productivity variations.
