Pore water records of Δ18O and [Cl> from ODP Site 1063A on the Bermuda Rise constrain the change in seawater Δ18O and salinity from the Last Glacial Maximum (LGM) to the Holocene to be 0.75¿0.05? and 2.5¿0.1% respectively. Coupled with a measured benthic foraminiferal Δ18O change, this result means that bottom waters were 4.6¿0.8¿C cooler than the Holocene at the LGM and therefore at or near the seawater freezing point. Coupled Δ18O and chlorinity results give an extrapolated mean ocean LGM to Holocene change in Δ18O of 0.95¿0.09?. These data also constrain the past southern source deep-water salinity to be 35.76¿0.04 psu, which is within error of the mean deep ocean value for this time. ¿ 2001 American Geophysical Union
