9313821 McIntyre The goal of this study is to determine if solar forcing alters climate at the millennial time scales with the help of calcareous planktonic and isotopic proxies. This will be done in three steps. First, the response of surface waters of equatorial Atlantic to climate controlled wind variations will be documented. Second, these signals will be compared with time series from other regions to determine if these short period signals are global. Third, a sine wave signal of millennial response of ocean/climate will need constructed which can be used bother for comparison with other records and as a predictive template.

9313821麦金太尔这项研究的目的是确定太阳能在钙质浮游生物和同位素代理的帮助下是否在千禧一代尺度上改变气候。这将分三个步骤完成。首先，将记录赤道大西洋对气候控制风变化的地表水的反应。其次，将将这些信号与其他地区的时间序列进行比较，以确定这些短期信号是否全局。第三，需要构建海洋/气候的千禧一代响应的正弦波信号，可以使用它来与其他记录和作为预测模板进行比较。
