DESCRIPTION: 
ODP site 980 0-1 Myr benthic stable isotope data.
Latitude: 55°29.1'N   
Longitude: 14°42.1'W   
Bathymetry: 2168 m

Data File Columns
ODP980-isotope.xls:
Depth (mcd) = meters composite depth
Age (ka) = age in thousands of years
Cw d13C = Cibicidoides wuellerstorfi delta 13C vs VPDB
Cw d18O = Cibicidoides wuellerstorfi delta 18O vs VPDB

ODP980-agemodel.txt
Depth (mcd) = meters composite depth
Age (ka) = age in thousands of years

Data precision:
Data for the 0-350 ka interval (McManus et al., 1999), 
the 350-500 ka interval (Oppo et al., 1998), and 
the 500-1000 ka interval (Flower et al., 2000) have analytical 
precision better than 0.05 ‰ and 0.08 ‰ for d13C and d18O, 
respectively.  Sample replicates indicate a reproducibility 
of better than 0.2 ‰ for both d13C and d18O.
