The Last 41.000 Years Fluctuation in Atmosperic CO2 Concentration Inferred from The Changes in Oxygen and Carbon Stable Isotopes Ratios of The Marine Sediment
The past atmospheric CO2 concentrations were reconstructed based on the results of measurements of stable oxygen and carbon isotopic ratios of fossil foraminifer and total organic carbon contained in marine sediment taken from the Okinawa Trough, East China Sea. In this study, we utilized two models...
