This proposal is funded to calibrate the Mg/Ca temperature proxy in multiple species of planktic foraminifers with hydrographic data from the Cariaco, Guaymas and Santa Barbara Basins to refine the Mg/Ca temperature proxy in multiple species of planktic foraminifers. The Mg/Ca proxy will then be compared with oxygen isotope and alkenone measurements on the same sediment trap samples. The Mg/Ca calibrations will be used to reconstruct the Holocene of the Cariaco and Santa Barbara Basins from laminated cores which have been AMS 14C dated and have detailed foraminiferal oxygen isotope records.

该提案的资助是为了校准来自Cariaco，Guaymas和Santa Barbara盆地的水文数据的多种木板有孔虫数据的MG/CA温度代理，以优化多种板岩有孔虫的MG/CA温度代理。 然后将将MG/CA代理与同一沉积物陷阱样品上的氧同位素和烯酮测量值进行比较。 MG/CA校准将用于重建层压板的Cariaco和Santa Basins盆地的全新世，这些核心已过时，并详细介绍了有孔虫的氧同位素记录。
