RPGW: The Feasibility of Reconstructing Upper Ocean Flows from Density Gradients during the Last Gacial Maximum

这项规划补助金将探索根据海底有孔虫中氧同位素比率的成对垂直剖面计算上层海洋运输量的可行性。将对佛罗里达海峡东西两侧的岩心深度横断面进行现代至末次冰期的采样，根据有孔虫的氧同位素比率建立密度剖面，并得出对地转输送的估计。将特别注意估计各种假设引起的误差的大小。

This Planning Grant will explore the feasibility of calculating upper ocean transports from paired vertical profiles of oxygen isotope ratios in benthic foraminifera. Depth transects of cores from the east and west sides of the Florida Straits, will be sampled for modern through last glacial periods, density profiles constructed from the foraminiferal oxygen isotope ratios, and estimates of geostrophic transport derived. Special attention will be given to estimating the magnitude of error introduced by various assumptions.
