| contents | Indian Ocean surface circulation is an important part of the global ocean conveyor belt, and is connected via two important gateways including the Indonesian Throughflow, and the Agulha Leakage. Changes in the surface hydrography of the Indian Ocean may therefore impact on the global overturning circulation. Here we present oxygen-isotopes and magnesium/calcium ratios from planktic foraminifer Globigernoides ruber from core site U1476 to reconstruct sea surface salinity and sea surface temperature in the Mozambique Channel, Indian Ocean for the past 1.2Ma. We investigated the changes in the surface hydrography of the Mid-to-Late Pleistocene and find an early salinification and warming during glacial cycles. |
