The proposed study will examine the timing and phasing of the warming of the ocean surface during the beginning of interglacial Marine Isotope Stages (MIS) 1 and 5. The primary goal is to verify the hypothesis whether the tropical ocean or the Northern North Atlantic is pacing climate change at the glacial/interglacial transitions. The change in sea-surface temperature (SST) in relation to sea-surface salinity (SSS) and global ice volume change will be deciphered by using a hitherto unique approach, namely the measurement of combined 44/40Ca, Mg/Ca and 18O in the same planktonic foraminiferal species in comparison to alkenone-based temperatures. The high-resolution multi-proxy data series will be gathered from tropical to high northern latitude ocean areas in the Atlantic Ocean, roughly following the pathway of ocean heat and moisture via the Gulf Stream system, and hence, covering areas with different evaporation/precipitation ratios. We will reconstruct these oceanic parameters for the surface ocean by using shallow-dwelling and by using deep-dwellers foraminifers for the subsurface ocean.

拟议的研究将审查海洋表面变暖的时间和阶段在间冰期海洋同位素阶段（MIS）1和5开始。主要目标是验证热带海洋或北方北大西洋是否在冰川/间冰期过渡期加速气候变化的假设。将使用一种迄今为止唯一的方法，即在相同的浮游有孔虫物种中测量结合的Ca ~（44）/40 Ca、Mg/Ca和Ca ~（18）O，并与基于烯酮的温度进行比较，来解释海表温度（SST）与海表盐度（SSS）和全球冰量变化的关系。高分辨率多代理数据系列将从大西洋热带到北方高纬度海洋地区收集，大致沿着海洋热量和水分通过墨西哥湾流系统的路径，因此，涵盖蒸发/降水比率不同的地区。我们将重建这些海洋参数的表面海洋使用浅居住和使用深居民有孔虫地下海洋。
