File  s664.iso 
This data set lists all 664 data published in this paper by species and lab as follows:
MIT = MIT DATA
WH = WHOI DATA
VGPRIS = CAL DATA
NJS = CAMBRIDGE DATA
All the CAL d18O has had 0.20‰ subtracted from it.


File s664.cibmean.iso
This is 664 data published first in this paper.  This data file has only 
cibicidoides data and duplicate analyses are averaged.  
Species adjustments are made.


File s607.iso
This is 607 benthic isotope data from the Pleistocene, most of which 
was published originally in Ruddiman et al. [1989]. 
(Note that some of the data at the very top is from a nearby piston core 
as explained in that paper).  Species adjustments have been made.


File s607.cibmean.iso
This is benthic 607 data which includes only Cibicidoides data and has 
duplicates averaged.  Note that data file goes well into Pliocene (~3.0 Ma).
Also includes IDs for 607 data.


File s677agenjs.iso
This is Shackleton's 677 benthic data [Shackleton, Berger,. and Peltier, 1990]
to his time scale.  Gaps are where only the benthic d18O data was good.  
Species adjustments made to d18O data.


File s849.iso
This is Mix et al. [1995] data.  Species adjustments made to d18O data.


File rc13229.iso
Data from Oppo et al. [1990].


File s552.cib.iso
This is benthic isotope data published by Shackleton.  
The data set includes only Cibicidoides data which has been adjusted.
