Hydrographic observations and ocean-atmosphere modeling indicate Red Sea deep water was episodically renewed by wintertime open-ocean deep convections during 1982-2001, suggesting a renewal time on the order of a decade. However, the long-term pacing of Red Sea deep water renewals is largely uncertain. We use an annually resolved coral oxygen isotope record of winter surface water conditions to show that the late twentieth century deep water renewals were probably unusual in the context of the preceding ~100 years. More frequent major events are detected during the late Little Ice Age, particularly during the early nineteenth century characterized by large tropical volcanic eruptions. We conclude that Red Sea deep water renewal time is on the order of a decade up to a century, depending on the mean climatic conditions and large-scale interannual climate forcing. #------------------
