ODP Site 982 Intermediate Water Variability Data.Entry ID: NOAA_NCDC_PALEO_1999-023
Abstract: ODP site 982 0-1 Myr stable isotopic, %carbonate, and IRD data.
Latitude: 57°30.8'N Longitude: 15°52.5'W Bathymetry: 1145 m
Data File Columns:
sect = section
interv = interval
MCD = meters composite depth
age (kyrs) = age in thousands of years
cib 18O = delta 18O Cibicidoides vs PDB
cib 13C = delta 13C Cibicidoides vs PDB
bull 18O = delta 18O Globigerina bulloides vs PDB
bull 13C = ... delta 13C Globigerina bulloides vs PDB
%CaCO3 = percent calcium carbonate of bulk sample
%IRD = percent ice rafted debris
isotopic data, Analytical precision, estimated by the standard deviation
(one sigma) of repeated analysis of a powdered carbonate standard (Carrara
Marble-UF, n = 636), was ±0.08 per mil for d18O (delta 18O) and ±0.05 per
mil for d13C. Sample reproducibility was estimated by the mean of the
difference of 456 paired replicate analyses of Cibicidoides that resulted
in a mean difference of 0.18 per mil for d18O and 0.14 per mil for d13C.
For G. bulloides, 176 paired analyses gave a mean difference of 0.16 per
mil for d18O and 0.18 per mil for d13C.
carbonate data, Precision was estimated to be ±0.7% (1 standard deviation)
on the basis of 241 measurements of reagent-grade (100%) CaCO3.
IRD data, The IRD Index (%IRD) was defined by the ratio of the IRD grains
to planktonic foraminifers and was calculated as [IRD / (IRD + Total
planktic foraminifera)] x 100 [Poore and Berggen, 1975].
