本研究将利用巴哈马海岸岩心深度样带对O-18、C-13和有机碳进行水深重建,并通过对赤道和亚热带南大西洋中、浅深度岩心底栖有孔虫同位素组成的时间序列分析,评价末次盛冰期温跃层和营养线性质的变化。这将有助于更好地了解冰期温跃层结构的化学和物理变化。
英文摘要
The study will evaluate changes in the nature of thermocline and nutricline during the last glacial maximum by bathymetric reconstruction of O-18 and C-13 and organic carbon using a depth transect of cores on the Bahama Banks, and by time-series analysis of isotopic composition of benthic foraminifera in the equatorial and subtropical south Atlantic in intermediate and shallow depth cores. It will lead to a better understanding of chemical and physical changes in the structure of thermocline during glacial periods.
