Benthic Foraminiferal Stable Isotopic Data from Ceara RiseEntry ID: NOAA_NCDC_PALEO_2000-029
Abstract: This data set consists of Benthic Foraminiferal Stable Isotopic Data from Ceara
The data are presented with respect to VPDB based on an published values for
NBS-19 of -2.20 for 18O and 1.95 for 13C. Since they were first published, we
have undertaken an extensive intercalibration of our laboratory with a large
segment of the paleoceanography research community. The results of this
... intercalibration are published in:
Ostermann, D. R. and W. B. Curry, Calibration of stable isotope data: An
enriched 18O standard used for source gas mixing detection and correction,
Paleoceanography, v. 15, pp. 353-360,2000.
As a result of this intercalibration, we discovered that our original data
needed a small revision. Thus we provide here both the original data as
published, and the revised data based on our further evaluations of mass
spectrometer performance. The differences between the data sets are small
(<0.05 permil for 13C and <~0.1 permil for 18O for the planktonic
foraminifera, ~0.15 to 0.2 permil for the benthic foraminifera), but large
enough to warrant recalculation. The corrections are also dependent on sample
size and isotopic composition, so it is not possible to subtract a constant
from the original to obtain the revised data. It is this revised data that we
recommend be used by interested researchers.
Additional data was added to the data set in the following contribution:
