NOAA/NGDC Paleoclimatology Program, Boulder CO, USA. ftp://ftp.ncdc.noaa.gov/pub/data/paleo/icecore/antarctica/vostok/deutnat.txt Temperature reconstruction is offered within the dataset. Benthic foram data: Lisiecki, L. E., and M. E. Raymo (2005), A Pliocene-Pleistocene stack of 57 globally distributed benthic d18O records, Paleoceanography,20, PA1003, doi:10.1029/2004PA001071. http://lorraine-lisiecki.com/stack.html A definitive temperature reconstruction is not offered within the data set. But from: http://lorraine-lisiecki.com/thesis_appendix.html#2-Appendix-B-The-d18O-of-Foraminifera is the statement: "A large portion change in d18Oc records is thought to result of the sequestration of isotopically light oxygen (16O) in large continental ice sheets, resulting in ocean water that has a larger proportion of 18O." Thus reduction of oxygen 18 (which is upward on the graph) indicates warmer conditions and higher sealevel.
