Late quaternary Southern Indian Ocean circulation

The climate of the Southern Indian Ocean is controled by the distinctive mid-to-high latitude oceanographic circulation features of the region. The oceanographic features have distinctive biotic signatures, which can be recognized in surface sediment furnaces. Studies of the Southern Indian Ocean down core time series indicated that oceanographic changes similar in magnitude to LGM-Modern shifts have been a regular, consistent and cyclic feature of the late Quaternary history of the Southern Indian Ocean. Oxygen isotopes and estimated sea-surface temperature records were used for this
