Collaborative Research: Reconstructing the Temperature and Salinity of the Glacial Ocean from Deep-Sea Pore Fluids

摘要：这项研究将从深海沉积物中获得孔隙水中氧同位素、氚/氢和氯化物的数据，以重建最后一次冰盛期深海水域的温度、盐度和氧同位素组成。这些测量将能够建立冰川海洋的垂直密度梯度，并能够测试在冰川时期深水生产是由海冰控制的这一概念，以及在现代海洋中观察到的海水同位素组成和盐度之间的关系可能不适用于最后一次冰川盛期。

Summary: This study is will obtain data on oxygen isotope, deuterium/hydrogen and chloride values in pore waters from deep sea sediments to reconstruct the temperature, salinity, and oxygen isotope composition of deep ocean waters during the last glacial maximum. The measurements will allow construction of vertical density gradients of the glacial ocean and allow a test of the concept that deep water production was controlled by sea ice during glacial intervals and that the relationship between isotopic composition of sea water and salinity observed in the modern ocean may not hold for the last glacial maximum.
