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.

总结：这项研究将获得深海沉积物孔隙沃茨中氧同位素、氘/氢和氯值的数据，以重建末次盛冰期深海沃茨的温度、盐度和氧同位素组成。 这些测量将有助于建立冰川海洋的垂直密度梯度，并可检验以下概念：冰川期间深海水的产生是由海冰控制的，现代海洋中观测到的海水同位素组成与盐度之间的关系可能不适用于末次冰盛期。
