New information from ODP Site 1085 for Marine Isotope \nStages (MIS) 12–10 shows that glacial–interglacial productivity \ntrends linked to upwelling variability followed a pattern similar \nto the last glacial cycle, with maximums shortly before glacial \nmaxima, and minimums shortly before glacial terminations. \nDuring the MIS-11/10 transition, several periodic oscillations \nin productivity and monsoonal proxies are best explained by \nsouthwards shifts in the southern sub-tropical high-pressure \ncells followed by abrupt northwards shifts. Comparison to coeval \nsea-surface temperature measurements suggests that these monsoonal \ncycles were tightly coupled to anti-phased hemispheric climate \nchange, with an intensified summer monsoon during periods of \nNorthern (Southern) Hemisphere cooling (warming). The timing \nof these events suggests a pacing by insolation over precession \nperiods. A lack of similar regional circulation shifts during \nthe MIS-13/12 transition is likely due to the large equatorwards \nshift in the tropical convection zone that occurred during this \nextreme glaciation. \n","author":null,"citation":"Dickson, A.J., M.J.
