Cross spectral analysis (Blackman-Tukey) between the 2700 year records of coccolith mass of (Gephyrocapsa ericsonii, G. muelerae, E. huxleyi) and %G. oceanica in the Santa Barbara Basin. No-Zero coherence at 95% is higher than a confidence level of 0.705 (blue horizontal line). The bandwidth is 0.00093. Lengths of significant periods are indicated in the graph
