Last Interglacial Ocean of the Nordic Seas

从以前的古海洋学研究在东北大西洋，温暖的，亚热带地表水在中纬度地区的影响是更高的最后一次间冰期（MIS 5e）的高峰期比在全新世。然而，这样的发现是有点矛盾的数据从更北的节海，较低的海表温度和较大的季节性海冰可能存在于MIS 5e。计划中的研究试图通过解开MIS 5e期间整体大气-海洋强迫和随后的冰川强化时间（MIS 5d-a）引起的表面海洋特性来解决这一争议。工作重点是重建北欧东部海域的上层水柱特性，即，垂直和空间温盐梯度。一个深刻的微体古生物学的方法，使用dinocyts和精炼的南极有孔虫dietary将与地球化学和沉积代理相结合，如记录的多物种稳定的O/C同位素和冰筏碎片。

As inferred from previous paleoceanographic research in the northeast Atlantic, influence of warm, subtropical surface water at mid-latitudes was higher during the peak of the last interglaciation (MIS 5e) than in the Holocene. However, such finding is somewhat contradictory to data from further north in the Nodic seas, where lower sea furface temperatures and a larger seasonal sea-ice over probably existed during MIS 5e. The planned study tries to resolve this controversy by unravelling surface ocean properties as induced by overall atmospheric-oceanic forcing during MIS 5e and the ensuing time of glacial intensification (MIS 5d-a). Work will focus on reconstructiong upper water column properties in the eastern Nordic seas, i.e., vertical and spatial temperature-salinity gradients. A profound micropaleontological approach using dinocycts and refined planktic foraminiferal diversities will be applied in combination with geochemical and sedimentary proxies, such as records of multispecies stable O/C isotopes and ice-rafted debris.
