Heat Cycles of the Tropical Ocean Reservoir at Orbital Frequencies in the Pleistocene: Paleoestimation Part II

这是对纳米浮游生物物种Florisphaera prounda作为古海洋学代理的工作的延续。本研究将以该spp为代表，估计大西洋热带湍流层平均热含量的时空变化。结果被认为对大气-海洋模式的验证很重要。此外，还将对太平洋赤道地区的埃克曼辐散进行类似的分析，以了解太平洋是否以与大西洋相同的方式响应在营养线/温跃层动力学方面的轨道强迫。此外，还将研究深孔菌的时间分布潜力。

This is a continuation of the work on the nannoplankton species Florisphaera profunda as a paleoceanographic proxy. The study will estimate spatial and temporal variations in mean heat content of tropical turbulent layer of the Atlantic using this spp. as a proxy. Results are considered important for atmosphere-ocean model validation. In addition, similar analyses of equatorial regions of Ekman divergence in the Pacific will also be made to see if the Pacific behaves the same way as the Atlantic in response to orbital forcing in terms of nutricline/thermocline dynamics. Chronological potential of F. profunda will also be investigated.
