Dansgaard-Oeschger cycles, high-frequency climate oscillations with 1000, 1450, and 3000 year cyclicities, have Heinrich events of sudden iceberg discharge associated with them. The first section of the paper examines how both the Dansgaard-Oeschger cycles and the Heinrich events have global signatures. In the second section, evidence is presented to show a subtropical equivalent of these events using three deep-sea sediment cores from the low-latitude monsoon climate of the Arabian Sea. The eolian dust in the cores shows humid intervals correlating with the Greenland temperature record, the stadial/interstadial succession in the Pacific Santa Barbara Basin and the temperature maxima in the Antarctic Vostok ice core, as well as Dansgaard-Oeschger variability, indicating that these cycles are not confined to the Northern Hemisphere or the high latitudes.
