A radiocarbon-dated sediment core from the flat top of Wadia Guyot at a 1500-m water depth in the Eastern Arabian Sea (EAS), western margin of India, preserves the records of past changes in water column temperatures and surface productivity. The time-series of oxygen isotope record extracted from planktonic foraminifera Globigerinoides (G.) sacculifer allows us to identify the Last Glacial Maximum...
The top 1m radiocarbon dated section of a 5.6m long sediment core retrieved from the Equatorial Indian Ocean is studied for productivity changes in response to climate variability that have taken place during the last ~33kyr. The robust indicators of marine productivity such as phytol and brassicasterol exhibit distinctly higher contents (av. 5.8ng/g and 4.8ng/g respectively) during the LGM (25-17kyBP)...
