Here we present data from the north-western \nIndian Ocean which indicate that the timing of maxima in northward \nextensions of glacial Antarctic Intermediate Water (GAAIW) coincides \nwith dramatically reduced thermohaline overturn in the North Atlantic \nassociated with the Heinrich-ice surge events (HE). The repeated \nexpansion of the GAAIW during HEs, recorded far north of the equator \nin the Arabian Sea, suggests that southern hemisphere driven\nintermediate water mass variability forms an integral part of \nthe inter-hemisphere asynchronous climate change behavior at \nthe millennial time-scale. \n\n","author":null,"citation":"Jung, S.J.A., D.
