We then apply these regressions to long benthic \nisotopic records retrieved at one North Atlantic and one Equatorial \nPacific site to build a composite RSL curve, as well as the \nassociated confidence interval, over the last four climatic cycles. \nOur proposed reconstruction of RSL is in good agreement with \nthe sparse RSL data available prior to the last climatic cycle. \nWe compute bottom water temperature changes at the two sites \nand at one Southern Indian Ocean site, taking into account potential \nvariations in North Atlantic local deep-water d18O. Our results \nindicate that a Last Glacial Maximum (LGM) enrichment of the ocean \nmean oxygen isotopic ratio of 0.95% is the lowest value compatible \nwith unfrozen deep waters in the Southern Indian Ocean if local deep \nwater d18O did not increase during glacials with respect to present. \nSuch a value of the LGM mean ocean isotopic enrichment would impose \na maximum decrease in local bottom water d18O at the North Atlantic \nsite of 0.30% during glacials. \n\n","author":null,"citation":"Waelbroeck, C., L.
