We present a reconstruction of El Nino Southern Oscillation (ENSO) variability spanning the Medieval Climate Anomaly (MCA, A. D. 800-1300) and the Little Ice Age (LIA, A. D. 1500-1850). Changes in ENSO are estimated by comparing the spread and symmetry of delta O-18 values of individual specimens of the thermocline-dwelling planktonic foraminifer Pulleniatina obliquiloculata extracted from discrete time horizons of a sediment core collected in the Sulawesi Sea, at the edge of the western tropical Pacific warm pool. The spread of individual delta O-18 values is interpreted to be a measure of the strength of both phases of ENSO while the symmetry of the delta O-18 distributions is used to evaluate the relative strength/ frequency of El Ni o and La Ni a... |
