The middle Miocene transition witnessed rapid fluctuations in oceanographic and climatic systems. However, very limited work has been attempted in Miocene sediments of the Northern Indian Ocean to identify these changes. Here we present the first detailed δ13C and δ18O records of surface and deep dwelling foraminifera from ODP site 758 in the Northeast Indian Ocean, located atop the Ninetyeast Ridge...
A high resolution record of the Indian summer monsoon (ISM) is generated using a δ 18 O time series from a stalagmite collected from the Valmiki cave in southern India. This record covers a time span of ~1000years from 15,700 to 14,700yr BP (before 1950AD) with an average sampling resolution of ~5years. High amplitude δ 18 O variation in this record reflects abrupt changes in ISM activity...
